-=head1 DESCRIPTION
-
-The function EVP_PKEY_CTX_ctrl() sends a control operation to the context
-B<ctx>. The key type used must match B<keytype> if it is not -1. The parameter
-B<optype> is a mask indicating which operations the control can be applied to.
-The control command is indicated in B<cmd> and any additional arguments in
-B<p1> and B<p2>.
-
-Applications will not normally call EVP_PKEY_CTX_ctrl() directly but will
-instead call one of the algorithm specific macros below.
-
-The function EVP_PKEY_CTX_ctrl_str() allows an application to send an algorithm
-specific control operation to a context B<ctx> in string form. This is
-intended to be used for options specified on the command line or in text
-files. The commands supported are documented in the openssl utility
-command line pages for the option B<-pkeyopt> which is supported by the
-B<pkeyutl>, B<genpkey> and B<req> commands.
-
-All the remaining "functions" are implemented as macros.
-
-The EVP_PKEY_CTX_set_signature_md() macro sets the message digest type used
-in a signature. It can be used with any public key algorithm supporting
-signature operations.
-
-The macro EVP_PKEY_CTX_set_rsa_padding() sets the RSA padding mode for B<ctx>.
-The B<pad> parameter can take the value RSA_PKCS1_PADDING for PKCS#1 padding,
-RSA_SSLV23_PADDING for SSLv23 padding, RSA_NO_PADDING for no padding,
-RSA_PKCS1_OAEP_PADDING for OAEP padding (encrypt and decrypt only),
-RSA_X931_PADDING for X9.31 padding (signature operations only) and 
-RSA_PKCS1_PSS_PADDING (sign and verify only).
-
-Two RSA padding modes behave differently if EVP_PKEY_CTX_set_signature_md()
-is used. If this macro is called for PKCS#1 padding the plaintext buffer is
-an actual digest value and is encapsulated in a DigestInfo structure according
-to PKCS#1 when signing and this structure is expected (and stripped off) when
-verifying. If this control is not used with RSA and PKCS#1 padding then the
-supplied data is used directly and not encapsulated. In the case of X9.31
-padding for RSA the algorithm identifier byte is added or checked and removed
-if this control is called. If it is not called then the first byte of the plaintext buffer is expected to be the algorithm identifier byte.
-
-The EVP_PKEY_CTX_set_rsa_pss_saltlen() macro sets the RSA PSS salt length to
-B<len> as its name implies it is only supported for PSS padding.  Two special
-values are supported: -1 sets the salt length to the digest length. When
-signing -2 sets the salt length to the maximum permissible value. When
-verifying -2 causes the salt length to be automatically determined based on the
-B<PSS> block structure. If this macro is not called a salt length value of -2
-is used by default.
-
-The EVP_PKEY_CTX_set_rsa_rsa_keygen_bits() macro sets the RSA key length for
-RSA key genration to B<bits>. If not specified 1024 bits is used.
-
-The EVP_PKEY_CTX_set_rsa_keygen_pubexp() macro sets the public exponent value
-for RSA key generation to B<pubexp> currently it should be an odd integer. The
-B<pubexp> pointer is used internally by this function so it should not be 
-modified or free after the call. If this macro is not called then 65537 is used.
-
-The macro EVP_PKEY_CTX_set_dsa_paramgen_bits() sets the number of bits used
-for DSA parameter generation to B<bits>. If not specified 1024 is used.
-
-The macro EVP_PKEY_CTX_set_dh_paramgen_prime_len() sets the length of the DH
-prime parameter B<p> for DH parameter generation. If this macro is not called
-then 1024 is used.
-
-The EVP_PKEY_CTX_set_dh_paramgen_generator() macro sets DH generator to B<gen>
-for DH parameter generation. If not specified 2 is used.
-
-The EVP_PKEY_CTX_set_ec_paramgen_curve_nid() sets the EC curve for EC parameter
-generation to B<nid>. For EC parameter generation this macro must be called
-or an error occurs because there is no default curve.
-
-=head1 RETURN VALUES
-
-EVP_PKEY_CTX_ctrl() and its macros return a positive value for success and 0
-or a negative value for failure. In particular a return value of -2
-indicates the operation is not supported by the public key algorithm.
