 These functions manipulate the B<X509_VERIFY_PARAM> structure associated with
@@ -61,12 +74,63 @@ X509_VERIFY_PARAM_set_depth() sets the maximum verification depth to B<depth>.
 That is the maximum number of untrusted CA certificates that can appear in a
 chain.
 
+X509_VERIFY_PARAM_set1_host() sets the expected DNS hostname to
+B<name> clearing any previously specified host name or names.  If
+B<name> is NULL, or empty the list of hostnames is cleared, and
+name checks are not performed on the peer certificate.  If B<name>
+is NUL-terminated, B<namelen> may be zero, otherwise B<namelen>
+must be set to the length of B<name>.  When a hostname is specified,
+certificate verification automatically invokes L<X509_check_host(3)>
+with flags equal to the B<flags> argument given to
+B<X509_VERIFY_PARAM_set_hostflags()> (default zero).  Applications
+are strongly advised to use this interface in preference to explicitly
+calling L<X509_check_host(3)>, hostname checks are out of scope
+with the DANE-EE(3) certificate usage, and the internal check will
+be suppressed as appropriate when DANE support is added to OpenSSL.
+
+X509_VERIFY_PARAM_add1_host() adds B<name> as an additional reference
+identifer that can match the peer's certificate.  Any previous names
+set via X509_VERIFY_PARAM_set1_host() or X509_VERIFY_PARAM_add1_host()
+are retained, no change is made if B<name> is NULL or empty.  When
+multiple names are configured, the peer is considered verified when
+any name matches.
+
+X509_VERIFY_PARAM_get0_peername() returns the DNS hostname or subject
+CommonName from the peer certificate that matched one of the reference
+identifiers.  When wildcard matching is not disabled, or when a
+reference identifier specifies a parent domain (starts with ".")
+rather than a hostname, the peer name may be a wildcard name or a
+sub-domain of the reference identifier respectively.  The return
+string is allocated by the library and is no longer valid once the
+associated B<param> argument is freed.  Applications must not free
+the return value.
+
+X509_VERIFY_PARAM_set1_email() sets the expected RFC822 email address to
+B<email>.  If B<email> is NUL-terminated, B<emaillen> may be zero, otherwise
+B<emaillen> must be set to the length of B<email>.  When an email address
+is specified, certificate verification automatically invokes
+L<X509_check_email(3)>.
+
+X509_VERIFY_PARAM_set1_ip() sets the expected IP address to B<ip>.
+The B<ip> argument is in binary format, in network byte-order and
+B<iplen> must be set to 4 for IPv4 and 16 for IPv6.  When an IP
+address is specified, certificate verification automatically invokes
+L<X509_check_ip(3)>.
+
+X509_VERIFY_PARAM_set1_ip_asc() sets the expected IP address to
+B<ipasc>.  The B<ipasc> argument is a NUL-terminal ASCII string:
+dotted decimal quad for IPv4 and colon-separated hexadecimal for
+IPv6.  The condensed "::" notation is supported for IPv6 addresses.
