  OpenSSL CHANGES
  _______________
 
+ Changes between 1.0.2d and 1.0.2e [3 Dec 2015]
+
+  *) BN_mod_exp may produce incorrect results on x86_64
+
+     There is a carry propagating bug in the x86_64 Montgomery squaring
+     procedure. No EC algorithms are affected. Analysis suggests that attacks
+     against RSA and DSA as a result of this defect would be very difficult to
+     perform and are not believed likely. Attacks against DH are considered just
+     feasible (although very difficult) because most of the work necessary to
+     deduce information about a private key may be performed offline. The amount
+     of resources required for such an attack would be very significant and
+     likely only accessible to a limited number of attackers. An attacker would
+     additionally need online access to an unpatched system using the target
+     private key in a scenario with persistent DH parameters and a private
+     key that is shared between multiple clients. For example this can occur by
+     default in OpenSSL DHE based SSL/TLS ciphersuites.
+
+     This issue was reported to OpenSSL by Hanno Böck.
+     (CVE-2015-3193)
+     [Andy Polyakov]
+
+  *) Certificate verify crash with missing PSS parameter
+
+     The signature verification routines will crash with a NULL pointer
+     dereference if presented with an ASN.1 signature using the RSA PSS
+     algorithm and absent mask generation function parameter. Since these
+     routines are used to verify certificate signature algorithms this can be
+     used to crash any certificate verification operation and exploited in a
+     DoS attack. Any application which performs certificate verification is
+     vulnerable including OpenSSL clients and servers which enable client
+     authentication.
+
+     This issue was reported to OpenSSL by Loïc Jonas Etienne (Qnective AG).
+     (CVE-2015-3194)
+     [Stephen Henson]
+
+  *) X509_ATTRIBUTE memory leak
+
+     When presented with a malformed X509_ATTRIBUTE structure OpenSSL will leak
+     memory. This structure is used by the PKCS#7 and CMS routines so any
+     application which reads PKCS#7 or CMS data from untrusted sources is
+     affected. SSL/TLS is not affected.
+
+     This issue was reported to OpenSSL by Adam Langley (Google/BoringSSL) using
+     libFuzzer.
+     (CVE-2015-3195)
+     [Stephen Henson]
+
+  *) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs.
+     This changes the decoding behaviour for some invalid messages,
+     though the change is mostly in the more lenient direction, and
+     legacy behaviour is preserved as much as possible.
+     [Emilia Käsper]

+  *) Race condition handling PSK identify hint
+
+     If PSK identity hints are received by a multi-threaded client then
+     the values are wrongly updated in the parent SSL_CTX structure. This can
+     result in a race condition potentially leading to a double free of the

+HOW TO CONTRIBUTE TO OpenSSL
+----------------------------
+
+Development is coordinated on the openssl-dev mailing list (see
+http://www.openssl.org for information on subscribing). If you
+would like to submit a patch, send it to rt@openssl.org with
+the string "[PATCH]" in the subject. Please be sure to include a
+textual explanation of what your patch does.
+
+You can also make GitHub pull requests. If you do this, please also send
+mail to rt@openssl.org with a brief description and a link to the PR so
+that we can more easily keep track of it.
+
+If you are unsure as to whether a feature will be useful for the general
+OpenSSL community please discuss it on the openssl-dev mailing list first.
+Someone may be already working on the same thing or there may be a good
+reason as to why that feature isn't implemented.
+
+Patches should be as up to date as possible, preferably relative to the
+current Git or the last snapshot. They should follow our coding style
+(see https://www.openssl.org/policies/codingstyle.html) and compile without
+warnings using the --strict-warnings flag.  OpenSSL compiles on many varied
+platforms: try to ensure you only use portable features.
+
+Our preferred format for patch files is "git format-patch" output. For example
+to provide a patch file containing the last commit in your local git repository
+use the following command:
+
+# git format-patch --stdout HEAD^ >mydiffs.patch
+
+Another method of creating an acceptable patch file without using git is as
+follows:
+
+# cd openssl-work
+# [your changes]
+# ./Configure dist; make clean
+# cd ..
+# diff -ur openssl-orig openssl-work > mydiffs.patch

-===============================================================================
-
-[MISC] ========================================================================
-
-* Which is the current version of OpenSSL?
-
-The current version is available from <URL: http://www.openssl.org>.
-OpenSSL 1.0.1a was released on Apr 19th, 2012.
-
-In addition to the current stable release, you can also access daily
-snapshots of the OpenSSL development version at <URL:
-ftp://ftp.openssl.org/snapshot/>, or get it by anonymous Git access.
-
-
-* Where is the documentation?
-
-OpenSSL is a library that provides cryptographic functionality to
-applications such as secure web servers.  Be sure to read the
-documentation of the application you want to use.  The INSTALL file
-explains how to install this library.
-
-OpenSSL includes a command line utility that can be used to perform a
-variety of cryptographic functions.  It is described in the openssl(1)
-manpage.  Documentation for developers is currently being written. Many
-manual pages are available; overviews over libcrypto and
-libssl are given in the crypto(3) and ssl(3) manpages.
-
-The OpenSSL manpages are installed in /usr/local/ssl/man/ (or a
-different directory if you specified one as described in INSTALL).
-In addition, you can read the most current versions at
-<URL: http://www.openssl.org/docs/>. Note that the online documents refer
-to the very latest development versions of OpenSSL and may include features
-not present in released versions. If in doubt refer to the documentation
-that came with the version of OpenSSL you are using. The pod format
-documentation is included in each OpenSSL distribution under the docs
-directory.
-
-There is some documentation about certificate extensions and PKCS#12
-in doc/openssl.txt
-
-The original SSLeay documentation is included in OpenSSL as
-doc/ssleay.txt.  It may be useful when none of the other resources
-help, but please note that it reflects the obsolete version SSLeay
-0.6.6.
-
-
-* How can I contact the OpenSSL developers?
-
-The README file describes how to submit bug reports and patches to
-OpenSSL.  Information on the OpenSSL mailing lists is available from
-<URL: http://www.openssl.org>.
-
-
-* Where can I get a compiled version of OpenSSL?
-
-You can finder pointers to binary distributions in
-<URL: http://www.openssl.org/related/binaries.html> .
-
-Some applications that use OpenSSL are distributed in binary form.
-When using such an application, you don't need to install OpenSSL
-yourself; the application will include the required parts (e.g. DLLs).
-
-If you want to build OpenSSL on a Windows system and you don't have
-a C compiler, read the "Mingw32" section of INSTALL.W32 for information
-on how to obtain and install the free GNU C compiler.
-
-A number of Linux and *BSD distributions include OpenSSL.
-
-
-* Why aren't tools like 'autoconf' and 'libtool' used?
-
-autoconf will probably be used in future OpenSSL versions. If it was
-less Unix-centric, it might have been used much earlier.
-
-* What is an 'engine' version?
-
-With version 0.9.6 OpenSSL was extended to interface to external crypto
-hardware. This was realized in a special release '0.9.6-engine'. With
-version 0.9.7 the changes were merged into the main development line,
-so that the special release is no longer necessary.
-
-* How do I check the authenticity of the OpenSSL distribution?
-
-We provide MD5 digests and ASC signatures of each tarball.
-Use MD5 to check that a tarball from a mirror site is identical:
-
-   md5sum TARBALL | awk '{print $1;}' | cmp - TARBALL.md5
-
-You can check authenticity using pgp or gpg. You need the OpenSSL team
-member public key used to sign it (download it from a key server, see a
-list of keys at <URL: http://www.openssl.org/about/>). Then
-just do:
-
-   pgp TARBALL.asc
-
-* How does the versioning scheme work?
-
-After the release of OpenSSL 1.0.0 the versioning scheme changed. Letter 
-releases (e.g. 1.0.1a) can only contain bug and security fixes and no
-new features. Minor releases change the last number (e.g. 1.0.2) and 
-can contain new features that retain binary compatibility. Changes to
-the middle number are considered major releases and neither source nor
-binary compatibility is guaranteed.
-
-Therefore the answer to the common question "when will feature X be
-backported to OpenSSL 1.0.0/0.9.8?" is "never" but it could appear
-in the next minor release.
-
-* What happens when the letter release reaches z?
-
-It was decided after the release of OpenSSL 0.9.8y the next version should
-be 0.9.8za then 0.9.8zb and so on.
-
-
-[LEGAL] =======================================================================
-
-* Do I need patent licenses to use OpenSSL?
-
-For information on intellectual property rights, please consult a lawyer.
-The OpenSSL team does not offer legal advice.
-
-You can configure OpenSSL so as not to use IDEA, MDC2 and RC5 by using
- ./config no-idea no-mdc2 no-rc5
-
-
-* Can I use OpenSSL with GPL software?
-
-On many systems including the major Linux and BSD distributions, yes (the
-GPL does not place restrictions on using libraries that are part of the
-normal operating system distribution).
-
-On other systems, the situation is less clear. Some GPL software copyright
-holders claim that you infringe on their rights if you use OpenSSL with
-their software on operating systems that don't normally include OpenSSL.
-
-If you develop open source software that uses OpenSSL, you may find it
-useful to choose an other license than the GPL, or state explicitly that
-"This program is released under the GPL with the additional exemption that
-compiling, linking, and/or using OpenSSL is allowed."  If you are using
-GPL software developed by others, you may want to ask the copyright holder
-for permission to use their software with OpenSSL.
-
-
-[USER] ========================================================================
-
-* Why do I get a "PRNG not seeded" error message?
-
-Cryptographic software needs a source of unpredictable data to work
-correctly.  Many open source operating systems provide a "randomness
-device" (/dev/urandom or /dev/random) that serves this purpose.
-All OpenSSL versions try to use /dev/urandom by default; starting with
-version 0.9.7, OpenSSL also tries /dev/random if /dev/urandom is not
-available.
-
-On other systems, applications have to call the RAND_add() or
-RAND_seed() function with appropriate data before generating keys or
-performing public key encryption. (These functions initialize the
-pseudo-random number generator, PRNG.)  Some broken applications do
-not do this.  As of version 0.9.5, the OpenSSL functions that need
-randomness report an error if the random number generator has not been
-seeded with at least 128 bits of randomness.  If this error occurs and
-is not discussed in the documentation of the application you are
-using, please contact the author of that application; it is likely
-that it never worked correctly.  OpenSSL 0.9.5 and later make the
-error visible by refusing to perform potentially insecure encryption.
-
-If you are using Solaris 8, you can add /dev/urandom and /dev/random
-devices by installing patch 112438 (Sparc) or 112439 (x86), which are
-available via the Patchfinder at <URL: http://sunsolve.sun.com>
-(Solaris 9 includes these devices by default). For /dev/random support
-for earlier Solaris versions, see Sun's statement at
-<URL: http://sunsolve.sun.com/pub-cgi/retrieve.pl?doc=fsrdb/27606&zone_32=SUNWski>
-(the SUNWski package is available in patch 105710).
-
-On systems without /dev/urandom and /dev/random, it is a good idea to
-use the Entropy Gathering Demon (EGD); see the RAND_egd() manpage for
-details.  Starting with version 0.9.7, OpenSSL will automatically look
-for an EGD socket at /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool and
-/etc/entropy.
-
-Most components of the openssl command line utility automatically try
-to seed the random number generator from a file.  The name of the
-default seeding file is determined as follows: If environment variable
-RANDFILE is set, then it names the seeding file.  Otherwise if
-environment variable HOME is set, then the seeding file is $HOME/.rnd.
-If neither RANDFILE nor HOME is set, versions up to OpenSSL 0.9.6 will
-use file .rnd in the current directory while OpenSSL 0.9.6a uses no
-default seeding file at all.  OpenSSL 0.9.6b and later will behave
-similarly to 0.9.6a, but will use a default of "C:\" for HOME on
-Windows systems if the environment variable has not been set.
-
-If the default seeding file does not exist or is too short, the "PRNG
-not seeded" error message may occur.
-
-The openssl command line utility will write back a new state to the
-default seeding file (and create this file if necessary) unless
-there was no sufficient seeding.
-
-Pointing $RANDFILE to an Entropy Gathering Daemon socket does not work.
-Use the "-rand" option of the OpenSSL command line tools instead.
-The $RANDFILE environment variable and $HOME/.rnd are only used by the
-OpenSSL command line tools. Applications using the OpenSSL library
-provide their own configuration options to specify the entropy source,
-please check out the documentation coming the with application.
-
-
-* Why do I get an "unable to write 'random state'" error message?
-
-
-Sometimes the openssl command line utility does not abort with
-a "PRNG not seeded" error message, but complains that it is
-"unable to write 'random state'".  This message refers to the
-default seeding file (see previous answer).  A possible reason
-is that no default filename is known because neither RANDFILE
-nor HOME is set.  (Versions up to 0.9.6 used file ".rnd" in the
-current directory in this case, but this has changed with 0.9.6a.)
-
-
-* How do I create certificates or certificate requests?
-
-Check out the CA.pl(1) manual page. This provides a simple wrapper round
-the 'req', 'verify', 'ca' and 'pkcs12' utilities. For finer control check
-out the manual pages for the individual utilities and the certificate
-extensions documentation (in ca(1), req(1), x509v3_config(5) )
-
-
-* Why can't I create certificate requests?
-
-You typically get the error:
-
-	unable to find 'distinguished_name' in config
-	problems making Certificate Request
-
-This is because it can't find the configuration file. Check out the
-DIAGNOSTICS section of req(1) for more information.
-
-
-* Why does <SSL program> fail with a certificate verify error?
-
-This problem is usually indicated by log messages saying something like
-"unable to get local issuer certificate" or "self signed certificate".
-When a certificate is verified its root CA must be "trusted" by OpenSSL
-this typically means that the CA certificate must be placed in a directory
-or file and the relevant program configured to read it. The OpenSSL program
-'verify' behaves in a similar way and issues similar error messages: check
-the verify(1) program manual page for more information.
-
-
-* Why can I only use weak ciphers when I connect to a server using OpenSSL?
-
-This is almost certainly because you are using an old "export grade" browser
-which only supports weak encryption. Upgrade your browser to support 128 bit
-ciphers.
-
-
-* How can I create DSA certificates?
-
-Check the CA.pl(1) manual page for a DSA certificate example.
-
-
-* Why can't I make an SSL connection to a server using a DSA certificate?
-
-Typically you'll see a message saying there are no shared ciphers when
-the same setup works fine with an RSA certificate. There are two possible
-causes. The client may not support connections to DSA servers most web
-browsers (including Netscape and MSIE) only support connections to servers
-supporting RSA cipher suites. The other cause is that a set of DH parameters
-has not been supplied to the server. DH parameters can be created with the
-dhparam(1) command and loaded using the SSL_CTX_set_tmp_dh() for example:
-check the source to s_server in apps/s_server.c for an example.
-
-
-* How can I remove the passphrase on a private key?
-
-Firstly you should be really *really* sure you want to do this. Leaving
-a private key unencrypted is a major security risk. If you decide that
-you do have to do this check the EXAMPLES sections of the rsa(1) and
-dsa(1) manual pages.
-
-
-* Why can't I use OpenSSL certificates with SSL client authentication?
-
-What will typically happen is that when a server requests authentication
-it will either not include your certificate or tell you that you have
-no client certificates (Netscape) or present you with an empty list box
-(MSIE). The reason for this is that when a server requests a client
-certificate it includes a list of CAs names which it will accept. Browsers
-will only let you select certificates from the list on the grounds that
-there is little point presenting a certificate which the server will
-reject.
-
-The solution is to add the relevant CA certificate to your servers "trusted
-CA list". How you do this depends on the server software in uses. You can
-print out the servers list of acceptable CAs using the OpenSSL s_client tool:
-
-openssl s_client -connect www.some.host:443 -prexit
-
-If your server only requests certificates on certain URLs then you may need
-to manually issue an HTTP GET command to get the list when s_client connects:
-
-GET /some/page/needing/a/certificate.html
-
-If your CA does not appear in the list then this confirms the problem.
-
-
-* Why does my browser give a warning about a mismatched hostname?
-
-Browsers expect the server's hostname to match the value in the commonName
-(CN) field of the certificate. If it does not then you get a warning.
-
-
-* How do I install a CA certificate into a browser?
-
-The usual way is to send the DER encoded certificate to the browser as
-MIME type application/x-x509-ca-cert, for example by clicking on an appropriate
-link. On MSIE certain extensions such as .der or .cacert may also work, or you
-can import the certificate using the certificate import wizard.
-
-You can convert a certificate to DER form using the command:
-
-openssl x509 -in ca.pem -outform DER -out ca.der
-
-Occasionally someone suggests using a command such as:
-
-openssl pkcs12 -export -out cacert.p12 -in cacert.pem -inkey cakey.pem
-
-DO NOT DO THIS! This command will give away your CAs private key and
-reduces its security to zero: allowing anyone to forge certificates in
-whatever name they choose.
-
-* Why is OpenSSL x509 DN output not conformant to RFC2253?
-
-The ways to print out the oneline format of the DN (Distinguished Name) have
-been extended in version 0.9.7 of OpenSSL. Using the new X509_NAME_print_ex()
-interface, the "-nameopt" option could be introduded. See the manual
-page of the "openssl x509" commandline tool for details. The old behaviour
-has however been left as default for the sake of compatibility.
-
-* What is a "128 bit certificate"? Can I create one with OpenSSL?
-
-The term "128 bit certificate" is a highly misleading marketing term. It does
-*not* refer to the size of the public key in the certificate! A certificate
-containing a 128 bit RSA key would have negligible security.
-
-There were various other names such as "magic certificates", "SGC
-certificates", "step up certificates" etc.
-
-You can't generally create such a certificate using OpenSSL but there is no
-need to any more. Nowadays web browsers using unrestricted strong encryption
-are generally available.
-
-When there were tight restrictions on the export of strong encryption
-software from the US only weak encryption algorithms could be freely exported
-(initially 40 bit and then 56 bit). It was widely recognised that this was
-inadequate. A relaxation of the rules allowed the use of strong encryption but
-only to an authorised server.
-
-Two slighly different techniques were developed to support this, one used by
-Netscape was called "step up", the other used by MSIE was called "Server Gated
-Cryptography" (SGC). When a browser initially connected to a server it would
-check to see if the certificate contained certain extensions and was issued by
-an authorised authority. If these test succeeded it would reconnect using
-strong encryption.
-
-Only certain (initially one) certificate authorities could issue the
-certificates and they generally cost more than ordinary certificates.
-
-Although OpenSSL can create certificates containing the appropriate extensions
-the certificate would not come from a permitted authority and so would not
-be recognized.
-
-The export laws were later changed to allow almost unrestricted use of strong
-encryption so these certificates are now obsolete.
-
-
-* Why does OpenSSL set the authority key identifier (AKID) extension incorrectly?
-
-It doesn't: this extension is often the cause of confusion.
-
-Consider a certificate chain A->B->C so that A signs B and B signs C. Suppose
-certificate C contains AKID.
-
-The purpose of this extension is to identify the authority certificate B. This
-can be done either by including the subject key identifier of B or its issuer
-name and serial number.
-
-In this latter case because it is identifying certifcate B it must contain the
-issuer name and serial number of B.
-
-It is often wrongly assumed that it should contain the subject name of B. If it
-did this would be redundant information because it would duplicate the issuer
-name of C.
-
-
-* How can I set up a bundle of commercial root CA certificates?
-
-The OpenSSL software is shipped without any root CA certificate as the
-OpenSSL project does not have any policy on including or excluding
-any specific CA and does not intend to set up such a policy. Deciding
-about which CAs to support is up to application developers or
-administrators.
-
-Other projects do have other policies so you can for example extract the CA
-bundle used by Mozilla and/or modssl as described in this article:
-
-  <URL: http://www.mail-archive.com/modssl-users@modssl.org/msg16980.html>
-
-
-[BUILD] =======================================================================
-
-* Why does the linker complain about undefined symbols?
-
-Maybe the compilation was interrupted, and make doesn't notice that
-something is missing.  Run "make clean; make".
-
-If you used ./Configure instead of ./config, make sure that you
-selected the right target.  File formats may differ slightly between
-OS versions (for example sparcv8/sparcv9, or a.out/elf).
-
-In case you get errors about the following symbols, use the config
-option "no-asm", as described in INSTALL:
-
- BF_cbc_encrypt, BF_decrypt, BF_encrypt, CAST_cbc_encrypt,
- CAST_decrypt, CAST_encrypt, RC4, RC5_32_cbc_encrypt, RC5_32_decrypt,
- RC5_32_encrypt, bn_add_words, bn_div_words, bn_mul_add_words,
- bn_mul_comba4, bn_mul_comba8, bn_mul_words, bn_sqr_comba4,
- bn_sqr_comba8, bn_sqr_words, bn_sub_words, des_decrypt3,
- des_ede3_cbc_encrypt, des_encrypt, des_encrypt2, des_encrypt3,
- des_ncbc_encrypt, md5_block_asm_host_order, sha1_block_asm_data_order
-
-If none of these helps, you may want to try using the current snapshot.
-If the problem persists, please submit a bug report.
-
-
-* Why does the OpenSSL test fail with "bc: command not found"?
-
-You didn't install "bc", the Unix calculator.  If you want to run the
-tests, get GNU bc from ftp://ftp.gnu.org or from your OS distributor.
-
-
-* Why does the OpenSSL test fail with "bc: 1 no implemented"?
-
-On some SCO installations or versions, bc has a bug that gets triggered
-when you run the test suite (using "make test").  The message returned is
-"bc: 1 not implemented".
-
-The best way to deal with this is to find another implementation of bc
-and compile/install it.  GNU bc (see <URL: http://www.gnu.org/software/software.html>
-for download instructions) can be safely used, for example.
-
-
-* Why does the OpenSSL test fail with "bc: stack empty"?
-
-On some DG/ux versions, bc seems to have a too small stack for calculations
-that the OpenSSL bntest throws at it.  This gets triggered when you run the
-test suite (using "make test").  The message returned is "bc: stack empty".
-
-The best way to deal with this is to find another implementation of bc
-and compile/install it.  GNU bc (see <URL: http://www.gnu.org/software/software.html>
-for download instructions) can be safely used, for example.
-
-
-* Why does the OpenSSL compilation fail on Alpha Tru64 Unix?
-
-On some Alpha installations running Tru64 Unix and Compaq C, the compilation
-of crypto/sha/sha_dgst.c fails with the message 'Fatal:  Insufficient virtual
-memory to continue compilation.'  As far as the tests have shown, this may be
-a compiler bug.  What happens is that it eats up a lot of resident memory
-to build something, probably a table.  The problem is clearly in the
-optimization code, because if one eliminates optimization completely (-O0),
-the compilation goes through (and the compiler consumes about 2MB of resident
-memory instead of 240MB or whatever one's limit is currently).
-
-There are three options to solve this problem:
-
-1. set your current data segment size soft limit higher.  Experience shows
-that about 241000 kbytes seems to be enough on an AlphaServer DS10.  You do
-this with the command 'ulimit -Sd nnnnnn', where 'nnnnnn' is the number of
-kbytes to set the limit to.
-
-2. If you have a hard limit that is lower than what you need and you can't
-get it changed, you can compile all of OpenSSL with -O0 as optimization
-level.  This is however not a very nice thing to do for those who expect to
-get the best result from OpenSSL.  A bit more complicated solution is the
-following:
-
------ snip:start -----
-  make DIRS=crypto SDIRS=sha "`grep '^CFLAG=' Makefile.ssl | \
-       sed -e 's/ -O[0-9] / -O0 /'`"
-  rm `ls crypto/*.o crypto/sha/*.o | grep -v 'sha_dgst\.o'`
-  make
------ snip:end -----
-
-This will only compile sha_dgst.c with -O0, the rest with the optimization
-level chosen by the configuration process.  When the above is done, do the
-test and installation and you're set.
-
-3. Reconfigure the toolkit with no-sha0 option to leave out SHA0. It 
-should not be used and is not used in SSL/TLS nor any other recognized
-protocol in either case.
-
-
-* Why does the OpenSSL compilation fail with "ar: command not found"?
-
-Getting this message is quite usual on Solaris 2, because Sun has hidden
-away 'ar' and other development commands in directories that aren't in
-$PATH by default.  One of those directories is '/usr/ccs/bin'.  The
-quickest way to fix this is to do the following (it assumes you use sh
-or any sh-compatible shell):
-
------ snip:start -----
-  PATH=${PATH}:/usr/ccs/bin; export PATH
------ snip:end -----
-
-and then redo the compilation.  What you should really do is make sure
-'/usr/ccs/bin' is permanently in your $PATH, for example through your
-'.profile' (again, assuming you use a sh-compatible shell).
-
-
-* Why does the OpenSSL compilation fail on Win32 with VC++?
-
-Sometimes, you may get reports from VC++ command line (cl) that it
-can't find standard include files like stdio.h and other weirdnesses.
-One possible cause is that the environment isn't correctly set up.
-To solve that problem for VC++ versions up to 6, one should run
-VCVARS32.BAT which is found in the 'bin' subdirectory of the VC++
-installation directory (somewhere under 'Program Files').  For VC++
-version 7 (and up?), which is also called VS.NET, the file is called
-VSVARS32.BAT instead.
-This needs to be done prior to running NMAKE, and the changes are only
-valid for the current DOS session.
-
-
-* What is special about OpenSSL on Redhat?
-
-Red Hat Linux (release 7.0 and later) include a preinstalled limited
-version of OpenSSL. Red Hat has chosen to disable support for IDEA, RC5 and
-MDC2 in this version. The same may apply to other Linux distributions.
-Users may therefore wish to install more or all of the features left out.
-
-To do this you MUST ensure that you do not overwrite the openssl that is in
-/usr/bin on your Red Hat machine. Several packages depend on this file,
-including sendmail and ssh. /usr/local/bin is a good alternative choice. The
-libraries that come with Red Hat 7.0 onwards have different names and so are
-not affected. (eg For Red Hat 7.2 they are /lib/libssl.so.0.9.6b and
-/lib/libcrypto.so.0.9.6b with symlinks /lib/libssl.so.2 and
-/lib/libcrypto.so.2 respectively).
-
-Please note that we have been advised by Red Hat attempting to recompile the
-openssl rpm with all the cryptography enabled will not work. All other
-packages depend on the original Red Hat supplied openssl package. It is also
-worth noting that due to the way Red Hat supplies its packages, updates to
-openssl on each distribution never change the package version, only the
-build number. For example, on Red Hat 7.1, the latest openssl package has
-version number 0.9.6 and build number 9 even though it contains all the
-relevant updates in packages up to and including 0.9.6b.
-
-A possible way around this is to persuade Red Hat to produce a non-US
-version of Red Hat Linux.
-
-
-* Why does the OpenSSL compilation fail on MacOS X?
-
-If the failure happens when trying to build the "openssl" binary, with
-a large number of undefined symbols, it's very probable that you have
-OpenSSL 0.9.6b delivered with the operating system (you can find out by
-running '/usr/bin/openssl version') and that you were trying to build
-OpenSSL 0.9.7 or newer.  The problem is that the loader ('ld') in
-MacOS X has a misfeature that's quite difficult to go around.
-Look in the file PROBLEMS for a more detailed explanation and for possible
-solutions.
-
-
-* Why does the OpenSSL test suite fail on MacOS X?
-
-If the failure happens when running 'make test' and the RC4 test fails,
-it's very probable that you have OpenSSL 0.9.6b delivered with the
-operating system (you can find out by running '/usr/bin/openssl version')
-and that you were trying to build OpenSSL 0.9.6d.  The problem is that
-the loader ('ld') in MacOS X has a misfeature that's quite difficult to
-go around and has linked the programs "openssl" and the test programs
-with /usr/lib/libcrypto.dylib and /usr/lib/libssl.dylib instead of the
-libraries you just built.
-Look in the file PROBLEMS for a more detailed explanation and for possible
-solutions.
-
-* Why does the OpenSSL test suite fail in BN_sqr test [on a 64-bit platform]?
-
-Failure in BN_sqr test is most likely caused by a failure to configure the
-toolkit for current platform or lack of support for the platform in question.
-Run './config -t' and './apps/openssl version -p'. Do these platform
-identifiers match? If they don't, then you most likely failed to run
-./config and you're hereby advised to do so before filing a bug report.
-If ./config itself fails to run, then it's most likely problem with your
-local environment and you should turn to your system administrator (or
-similar). If identifiers match (and/or no alternative identifier is
-suggested by ./config script), then the platform is unsupported. There might
-or might not be a workaround. Most notably on SPARC64 platforms with GNU
-C compiler you should be able to produce a working build by running
-'./config -m32'. I understand that -m32 might not be what you want/need,
-but the build should be operational. For further details turn to
-<openssl-dev@openssl.org>.
-
-* Why does OpenBSD-i386 build fail on des-586.s with "Unimplemented segment type"?
-
-As of 0.9.7 assembler routines were overhauled for position independence
-of the machine code, which is essential for shared library support. For
-some reason OpenBSD is equipped with an out-of-date GNU assembler which
-finds the new code offensive. To work around the problem, configure with
-no-asm (and sacrifice a great deal of performance) or patch your assembler
-according to <URL: http://www.openssl.org/~appro/gas-1.92.3.OpenBSD.patch>.
-For your convenience a pre-compiled replacement binary is provided at
-<URL: http://www.openssl.org/~appro/gas-1.92.3.static.aout.bin>.
-Reportedly elder *BSD a.out platforms also suffer from this problem and
-remedy should be same. Provided binary is statically linked and should be
-working across wider range of *BSD branches, not just OpenBSD.
-
-* Why does the OpenSSL test suite fail in sha512t on x86 CPU?
-
-If the test program in question fails withs SIGILL, Illegal Instruction
-exception, then you more than likely to run SSE2-capable CPU, such as
-Intel P4, under control of kernel which does not support SSE2
-instruction extentions. See accompanying INSTALL file and
-OPENSSL_ia32cap(3) documentation page for further information.
-
-* Why does compiler fail to compile sha512.c?
-
-OpenSSL SHA-512 implementation depends on compiler support for 64-bit
-integer type. Few elder compilers [ULTRIX cc, SCO compiler to mention a
-couple] lack support for this and therefore are incapable of compiling
-the module in question. The recommendation is to disable SHA-512 by
-adding no-sha512 to ./config [or ./Configure] command line. Another
-possible alternative might be to switch to GCC.
-
-* Test suite still fails, what to do?
-
-Another common reason for failure to complete some particular test is
-simply bad code generated by a buggy component in toolchain or deficiency
-in run-time environment. There are few cases documented in PROBLEMS file,
-consult it for possible workaround before you beat the drum. Even if you
-don't find solution or even mention there, do reserve for possibility of
-a compiler bug. Compiler bugs might appear in rather bizarre ways, they
-never make sense, and tend to emerge when you least expect them. In order
-to identify one, drop optimization level, e.g. by editing CFLAG line in
-top-level Makefile, recompile and re-run the test.
-
-* I think I've found a bug, what should I do?
-
-If you are a new user then it is quite likely you haven't found a bug and
-something is happening you aren't familiar with. Check this FAQ, the associated
-documentation and the mailing lists for similar queries. If you are still
-unsure whether it is a bug or not submit a query to the openssl-users mailing
-list.
-
-
-* I'm SURE I've found a bug, how do I report it?
-
-Bug reports with no security implications should be sent to the request
-tracker. This can be done by mailing the report to <rt@openssl.org> (or its
-alias <openssl-bugs@openssl.org>), please note that messages sent to the
-request tracker also appear in the public openssl-dev mailing list.
-
-The report should be in plain text. Any patches should be sent as
-plain text attachments because some mailers corrupt patches sent inline.
-If your issue affects multiple versions of OpenSSL check any patches apply
-cleanly and, if possible include patches to each affected version.
-
-The report should be given a meaningful subject line briefly summarising the
-issue. Just "bug in OpenSSL" or "bug in OpenSSL 0.9.8n" is not very helpful.
-
-By sending reports to the request tracker the bug can then be given a priority
-and assigned to the appropriate maintainer. The history of discussions can be
-accessed and if the issue has been addressed or a reason why not. If patches
-are only sent to openssl-dev they can be mislaid if a team member has to
-wade through months of old messages to review the discussion.
-
-See also <URL: http://www.openssl.org/support/rt.html>
-
-
-* I've found a security issue, how do I report it?
-
-If you think your bug has security implications then please send it to
-openssl-security@openssl.org if you don't get a prompt reply at least 
-acknowledging receipt then resend or mail it directly to one of the
-more active team members (e.g. Steve).
-
-Note that bugs only present in the openssl utility are not in general
-considered to be security issues. 
-
-[PROG] ========================================================================
-
-* Is OpenSSL thread-safe?
-
-Yes (with limitations: an SSL connection may not concurrently be used
-by multiple threads).  On Windows and many Unix systems, OpenSSL
-automatically uses the multi-threaded versions of the standard
-libraries.  If your platform is not one of these, consult the INSTALL
-file.
-
-Multi-threaded applications must provide two callback functions to
-OpenSSL by calling CRYPTO_set_locking_callback() and
-CRYPTO_set_id_callback(), for all versions of OpenSSL up to and
-including 0.9.8[abc...]. As of version 1.0.0, CRYPTO_set_id_callback()
-and associated APIs are deprecated by CRYPTO_THREADID_set_callback()
-and friends. This is described in the threads(3) manpage.
-
-* I've compiled a program under Windows and it crashes: why?
-
-This is usually because you've missed the comment in INSTALL.W32.
-Your application must link against the same version of the Win32
-C-Runtime against which your openssl libraries were linked.  The
-default version for OpenSSL is /MD - "Multithreaded DLL".
-
-If you are using Microsoft Visual C++'s IDE (Visual Studio), in
-many cases, your new project most likely defaulted to "Debug
-Singlethreaded" - /ML.  This is NOT interchangeable with /MD and your
-program will crash, typically on the first BIO related read or write
-operation.
-
-For each of the six possible link stage configurations within Win32,
-your application must link  against the same by which OpenSSL was
-built.  If you are using MS Visual C++ (Studio) this can be changed
-by:
-
- 1. Select Settings... from the Project Menu.
- 2. Select the C/C++ Tab.
- 3. Select "Code Generation from the "Category" drop down list box
- 4. Select the Appropriate library (see table below) from the "Use
-    run-time library" drop down list box.  Perform this step for both
-    your debug and release versions of your application (look at the
-    top left of the settings panel to change between the two)
-
-    Single Threaded           /ML        -  MS VC++ often defaults to
-                                            this for the release
-                                            version of a new project.
-    Debug Single Threaded     /MLd       -  MS VC++ often defaults to
-                                            this for the debug version
-                                            of a new project.
-    Multithreaded             /MT
-    Debug Multithreaded       /MTd
-    Multithreaded DLL         /MD        -  OpenSSL defaults to this.
-    Debug Multithreaded DLL   /MDd
-
-Note that debug and release libraries are NOT interchangeable.  If you
-built OpenSSL with /MD your application must use /MD and cannot use /MDd.
-
-As per 0.9.8 the above limitation is eliminated for .DLLs. OpenSSL
-.DLLs compiled with some specific run-time option [we insist on the
-default /MD] can be deployed with application compiled with different
-option or even different compiler. But there is a catch! Instead of
-re-compiling OpenSSL toolkit, as you would have to with prior versions,
-you have to compile small C snippet with compiler and/or options of
-your choice. The snippet gets installed as
-<install-root>/include/openssl/applink.c and should be either added to
-your application project or simply #include-d in one [and only one]
-of your application source files. Failure to link this shim module
-into your application manifests itself as fatal "no OPENSSL_Applink"
-run-time error. An explicit reminder is due that in this situation
-[mixing compiler options] it is as important to add CRYPTO_malloc_init
-prior first call to OpenSSL.
-
-* How do I read or write a DER encoded buffer using the ASN1 functions?
-
-You have two options. You can either use a memory BIO in conjunction
-with the i2d_*_bio() or d2i_*_bio() functions or you can use the
-i2d_*(), d2i_*() functions directly. Since these are often the
-cause of grief here are some code fragments using PKCS7 as an example:
-
- unsigned char *buf, *p;
- int len;
-
- len = i2d_PKCS7(p7, NULL);
- buf = OPENSSL_malloc(len); /* or Malloc, error checking omitted */
- p = buf;
- i2d_PKCS7(p7, &p);
-
-At this point buf contains the len bytes of the DER encoding of
-p7.
-
-The opposite assumes we already have len bytes in buf:
-
- unsigned char *p;
- p = buf;
- p7 = d2i_PKCS7(NULL, &p, len);
-
-At this point p7 contains a valid PKCS7 structure or NULL if an error
-occurred. If an error occurred ERR_print_errors(bio) should give more
-information.
-
-The reason for the temporary variable 'p' is that the ASN1 functions
-increment the passed pointer so it is ready to read or write the next
-structure. This is often a cause of problems: without the temporary
-variable the buffer pointer is changed to point just after the data
-that has been read or written. This may well be uninitialized data
-and attempts to free the buffer will have unpredictable results
-because it no longer points to the same address.
-
-Memory allocation and encoding can also be combined in a single
-operation by the ASN1 routines:
-
- unsigned char *buf = NULL;	/* mandatory */
- int len;
- len = i2d_PKCS7(p7, &buf);
- if (len < 0)
-	/* Error */
- /* Do some things with 'buf' */
- /* Finished with buf: free it */
- OPENSSL_free(buf);
-
-In this special case the "buf" parameter is *not* incremented, it points
-to the start of the encoding.
-
-
-* OpenSSL uses DER but I need BER format: does OpenSSL support BER?
-
-The short answer is yes, because DER is a special case of BER and OpenSSL
-ASN1 decoders can process BER.
-
-The longer answer is that ASN1 structures can be encoded in a number of
-different ways. One set of ways is the Basic Encoding Rules (BER) with various
-permissible encodings. A restriction of BER is the Distinguished Encoding
-Rules (DER): these uniquely specify how a given structure is encoded.
-
-Therefore, because DER is a special case of BER, DER is an acceptable encoding
-for BER.
-
-
-* I've tried using <M_some_evil_pkcs12_macro> and I get errors why?
-
-This usually happens when you try compiling something using the PKCS#12
-macros with a C++ compiler. There is hardly ever any need to use the
-PKCS#12 macros in a program, it is much easier to parse and create
-PKCS#12 files using the PKCS12_parse() and PKCS12_create() functions
-documented in doc/openssl.txt and with examples in demos/pkcs12. The
-'pkcs12' application has to use the macros because it prints out 
-debugging information.
-
-
-* I've called <some function> and it fails, why?
-
-Before submitting a report or asking in one of the mailing lists, you
-should try to determine the cause. In particular, you should call
-ERR_print_errors() or ERR_print_errors_fp() after the failed call
-and see if the message helps. Note that the problem may occur earlier
-than you think -- you should check for errors after every call where
-it is possible, otherwise the actual problem may be hidden because
-some OpenSSL functions clear the error state.
-
-
-* I just get a load of numbers for the error output, what do they mean?
-
-The actual format is described in the ERR_print_errors() manual page.
-You should call the function ERR_load_crypto_strings() before hand and
-the message will be output in text form. If you can't do this (for example
-it is a pre-compiled binary) you can use the errstr utility on the error
-code itself (the hex digits after the second colon).
-
-
-* Why do I get errors about unknown algorithms?
-
-The cause is forgetting to load OpenSSL's table of algorithms with
-OpenSSL_add_all_algorithms(). See the manual page for more information. This
-can cause several problems such as being unable to read in an encrypted
-PEM file, unable to decrypt a PKCS#12 file or signature failure when
-verifying certificates.
-
-* Why can't the OpenSSH configure script detect OpenSSL?
-
-Several reasons for problems with the automatic detection exist.
-OpenSSH requires at least version 0.9.5a of the OpenSSL libraries.
-Sometimes the distribution has installed an older version in the system
-locations that is detected instead of a new one installed. The OpenSSL
-library might have been compiled for another CPU or another mode (32/64 bits).
-Permissions might be wrong.
-
-The general answer is to check the config.log file generated when running
-the OpenSSH configure script. It should contain the detailed information
-on why the OpenSSL library was not detected or considered incompatible.
-
-
-* Can I use OpenSSL's SSL library with non-blocking I/O?
-
-Yes; make sure to read the SSL_get_error(3) manual page!
-
-A pitfall to avoid: Don't assume that SSL_read() will just read from
-the underlying transport or that SSL_write() will just write to it --
-it is also possible that SSL_write() cannot do any useful work until
-there is data to read, or that SSL_read() cannot do anything until it
-is possible to send data.  One reason for this is that the peer may
-request a new TLS/SSL handshake at any time during the protocol,
-requiring a bi-directional message exchange; both SSL_read() and
-SSL_write() will try to continue any pending handshake.
-
-
-* Why doesn't my server application receive a client certificate?
-
-Due to the TLS protocol definition, a client will only send a certificate,
-if explicitly asked by the server. Use the SSL_VERIFY_PEER flag of the
-SSL_CTX_set_verify() function to enable the use of client certificates.
-
-
-* Why does compilation fail due to an undefined symbol NID_uniqueIdentifier?
-
-For OpenSSL 0.9.7 the OID table was extended and corrected. In earlier
-versions, uniqueIdentifier was incorrectly used for X.509 certificates.
-The correct name according to RFC2256 (LDAP) is x500UniqueIdentifier.
-Change your code to use the new name when compiling against OpenSSL 0.9.7.
-
-
-* I think I've detected a memory leak, is this a bug?
-
-In most cases the cause of an apparent memory leak is an OpenSSL internal table
-that is allocated when an application starts up. Since such tables do not grow
-in size over time they are harmless.
-
-These internal tables can be freed up when an application closes using various
-functions.  Currently these include following:
-
-Thread-local cleanup functions:
-
-  ERR_remove_state()
-
-Application-global cleanup functions that are aware of usage (and therefore
-thread-safe):
-
-  ENGINE_cleanup() and CONF_modules_unload()
-
-"Brutal" (thread-unsafe) Application-global cleanup functions:
-
-  ERR_free_strings(), EVP_cleanup() and CRYPTO_cleanup_all_ex_data().
-
-
-* Why does Valgrind complain about the use of uninitialized data?
-
-When OpenSSL's PRNG routines are called to generate random numbers the supplied
-buffer contents are mixed into the entropy pool: so it technically does not
-matter whether the buffer is initialized at this point or not.  Valgrind (and
-other test tools) will complain about this. When using Valgrind, make sure the
-OpenSSL library has been compiled with the PURIFY macro defined (-DPURIFY)
-to get rid of these warnings.
-
-
-* Why doesn't a memory BIO work when a file does?
-
-This can occur in several cases for example reading an S/MIME email message.
-The reason is that a memory BIO can do one of two things when all the data
-has been read from it.
-
-The default behaviour is to indicate that no more data is available and that
-the call should be retried, this is to allow the application to fill up the BIO
-again if necessary.
-
-Alternatively it can indicate that no more data is available and that EOF has
-been reached.
-
-If a memory BIO is to behave in the same way as a file this second behaviour
-is needed. This must be done by calling:
-
-   BIO_set_mem_eof_return(bio, 0);
-
-See the manual pages for more details.
-
-
-* Where are the declarations and implementations of d2i_X509() etc?
-
-These are defined and implemented by macros of the form:
-
-
- DECLARE_ASN1_FUNCTIONS(X509) and IMPLEMENT_ASN1_FUNCTIONS(X509)
-
-The implementation passes an ASN1 "template" defining the structure into an
-ASN1 interpreter using generalised functions such as ASN1_item_d2i().

  OVERVIEW
  --------
@@ -28,90 +28,39 @@
  The OpenSSL toolkit includes:
 
  libssl.a:
-     Implementation of SSLv2, SSLv3, TLSv1 and the required code to support
-     both SSLv2, SSLv3 and TLSv1 in the one server and client.
+     Provides the client and server-side implementations for SSLv3 and TLS.
 
  libcrypto.a:
-     General encryption and X.509 v1/v3 stuff needed by SSL/TLS but not
-     actually logically part of it. It includes routines for the following:
-
-     Ciphers
-        libdes - EAY's libdes DES encryption package which was floating
-                 around the net for a few years, and was then relicensed by
-                 him as part of SSLeay.  It includes 15 'modes/variations'
-                 of DES (1, 2 and 3 key versions of ecb, cbc, cfb and ofb;
-                 pcbc and a more general form of cfb and ofb) including desx
-                 in cbc mode, a fast crypt(3), and routines to read
-                 passwords from the keyboard.
-        RC4 encryption,
-        RC2 encryption      - 4 different modes, ecb, cbc, cfb and ofb.
-        Blowfish encryption - 4 different modes, ecb, cbc, cfb and ofb.
-        IDEA encryption     - 4 different modes, ecb, cbc, cfb and ofb.
-
-     Digests
-        MD5 and MD2 message digest algorithms, fast implementations,
-        SHA (SHA-0) and SHA-1 message digest algorithms,
-        MDC2 message digest. A DES based hash that is popular on smart cards.
-
-     Public Key
-        RSA encryption/decryption/generation.
-            There is no limit on the number of bits.
-        DSA encryption/decryption/generation.
-            There is no limit on the number of bits.
-        Diffie-Hellman key-exchange/key generation.
-            There is no limit on the number of bits.
-
-     X.509v3 certificates
-        X509 encoding/decoding into/from binary ASN1 and a PEM
-             based ASCII-binary encoding which supports encryption with a
-             private key.  Program to generate RSA and DSA certificate
-             requests and to generate RSA and DSA certificates.
-
-     Systems
-        The normal digital envelope routines and base64 encoding.  Higher
-        level access to ciphers and digests by name.  New ciphers can be
-        loaded at run time.  The BIO io system which is a simple non-blocking
-        IO abstraction.  Current methods supported are file descriptors,
-        sockets, socket accept, socket connect, memory buffer, buffering, SSL
-        client/server, file pointer, encryption, digest, non-blocking testing
-        and null.
-
-     Data structures
-        A dynamically growing hashing system
-        A simple stack.
-        A Configuration loader that uses a format similar to MS .ini files.
+     Provides general cryptographic and X.509 support needed by SSL/TLS but
+     not logically part of it.
 
  openssl:
      A command line tool that can be used for:
-        Creation of RSA, DH and DSA key parameters
+        Creation of key parameters
         Creation of X.509 certificates, CSRs and CRLs
-        Calculation of Message Digests
-        Encryption and Decryption with Ciphers
-        SSL/TLS Client and Server Tests
+        Calculation of message digests
+        Encryption and decryption
+        SSL/TLS client and server tests
         Handling of S/MIME signed or encrypted mail
+        And more...
 
  INSTALLATION
  ------------
 
- To install this package under a Unix derivative, read the INSTALL file.  For
- a Win32 platform, read the INSTALL.W32 file.  For OpenVMS systems, read
- INSTALL.VMS.
-
- Read the documentation in the doc/ directory.  It is quite rough, but it
- lists the functions; you will probably have to look at the code to work out
- how to use them. Look at the example programs.
-
- PROBLEMS
- --------
-
- For some platforms, there are some known problems that may affect the user
- or application author.  We try to collect those in doc/PROBLEMS, with current
- thoughts on how they should be solved in a future of OpenSSL.
+ See the appropriate file:
+        INSTALL         Linux, Unix, etc.
+        INSTALL.DJGPP   DOS platform with DJGPP
+        INSTALL.NW      Netware
+        INSTALL.OS2     OS/2
+        INSTALL.VMS     VMS
+        INSTALL.W32     Windows (32bit)

  HOW TO CONTRIBUTE TO OpenSSL
  ----------------------------
 
- Development is coordinated on the openssl-dev mailing list (see
- http://www.openssl.org for information on subscribing). If you
- would like to submit a patch, send it to openssl-bugs@openssl.org with
- the string "[PATCH]" in the subject. Please be sure to include a
- textual explanation of what your patch does.
-
- If you are unsure as to whether a feature will be useful for the general
- OpenSSL community please discuss it on the openssl-dev mailing list first.
- Someone may be already working on the same thing or there may be a good
- reason as to why that feature isn't implemented.
-
- Patches should be as up to date as possible, preferably relative to the
- current Git or the last snapshot. They should follow the coding style of
- OpenSSL and compile without warnings. Some of the core team developer targets
- can be used for testing purposes, (debug-steve64, debug-geoff etc). OpenSSL
- compiles on many varied platforms: try to ensure you only use portable
- features.
-
- Note: For legal reasons, contributions from the US can be accepted only
- if a TSU notification and a copy of the patch are sent to crypt@bis.doc.gov
- (formerly BXA) with a copy to the ENC Encryption Request Coordinator;
- please take some time to look at
-    http://www.bis.doc.gov/Encryption/PubAvailEncSourceCodeNofify.html [sic]
- and
-    http://w3.access.gpo.gov/bis/ear/pdf/740.pdf (EAR Section 740.13(e))
- for the details. If "your encryption source code is too large to serve as
- an email attachment", they are glad to receive it by fax instead; hope you
- have a cheap long-distance plan.
-
- Our preferred format for changes is "diff -u" output. You might
- generate it like this:
-
- # cd openssl-work
- # [your changes]
- # ./Configure dist; make clean
- # cd ..
- # diff -ur openssl-orig openssl-work > mydiffs.patch
+ See CONTRIBUTING
+
+ LEGALITIES
+ ----------
 
+ A number of nations, in particular the U.S., restrict the use or export
+ of cryptography. If you are potentially subject to such restrictions
+ you should seek competent professional legal advice before attempting to
+ develop or distribute cryptographic code.

+=head1 NAME
+
+SSL_check_chain - check certificate chain suitability
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_check_chain(SSL *s, X509 *x, EVP_PKEY *pk, STACK_OF(X509) *chain);
+
+=head1 DESCRIPTION
+
+SSL_check_chain() checks whether certificate B<x>, private key B<pk> and
+certificate chain B<chain> is suitable for use with the current session
+B<s>.
+
+=head1 RETURN VALUES
+
+SSL_check_chain() returns a bitmap of flags indicating the validity of the
+chain.
+
+B<CERT_PKEY_VALID>: the chain can be used with the current session.
+If this flag is B<not> set then the certificate will never be used even
+if the application tries to set it because it is inconsistent with the
+peer preferences.
+
+B<CERT_PKEY_SIGN>: the EE key can be used for signing.
+
+B<CERT_PKEY_EE_SIGNATURE>: the signature algorithm of the EE certificate is
+acceptable.
+
+B<CERT_PKEY_CA_SIGNATURE>: the signature algorithms of all CA certificates
+are acceptable.
+
+B<CERT_PKEY_EE_PARAM>: the parameters of the end entity certificate are
+acceptable (e.g. it is a supported curve).
+
+B<CERT_PKEY_CA_PARAM>: the parameters of all CA certificates are acceptable.
+
+B<CERT_PKEY_EXPLICIT_SIGN>: the end entity certificate algorithm
+can be used explicitly for signing (i.e. it is mentioned in the signature
+algorithms extension).
+
+B<CERT_PKEY_ISSUER_NAME>: the issuer name is acceptable. This is only
+meaningful for client authentication.
+
+B<CERT_PKEY_CERT_TYPE>: the certificate type is acceptable. Only meaningful
+for client authentication.
+
+B<CERT_PKEY_SUITEB>: chain is suitable for Suite B use.
+
+=head1 NOTES
+
+SSL_check_chain() must be called in servers after a client hello message or in
+clients after a certificate request message. It will typically be called
+in the certificate callback.
+
+An application wishing to support multiple certificate chains may call this
+function on each chain in turn: starting with the one it considers the
+most secure. It could then use the chain of the first set which returns
+suitable flags.
+
+As a minimum the flag B<CERT_PKEY_VALID> must be set for a chain to be
+usable. An application supporting multiple chains with different CA signature
+algorithms may also wish to check B<CERT_PKEY_CA_SIGNATURE> too. If no
+chain is suitable a server should fall back to the most secure chain which
+sets B<CERT_PKEY_VALID>.
+
+The validity of a chain is determined by checking if it matches a supported
+signature algorithm, supported curves and in the case of client authentication
+certificate types and issuer names.
+
+Since the supported signature algorithms extension is only used in TLS 1.2
+and DTLS 1.2 the results for earlier versions of TLS and DTLS may not be
+very useful. Applications may wish to specify a different "legacy" chain
+for earlier versions of TLS or DTLS.
