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.
+in a signature. It can be used in the RSA, DSA and ECDSA algorithms.
+
+The EVP_PKEY_CTX_get_signature_md() macro gets the message digest type used in a
+signature. It can be used in the RSA, DSA and ECDSA algorithms.
+
+Key generation typically involves setting up parameters to be used and
+generating the private and public key data. Some algorithm implementations
+allow private key data to be set explicitly using the EVP_PKEY_CTX_set_mac_key()
+macro. In this case key generation is simply the process of setting up the
+parameters for the key and then setting the raw key data to the value explicitly
+provided by that macro. Normally applications would call
+L<EVP_PKEY_new_raw_private_key(3)> or similar functions instead of this macro.
+
+The EVP_PKEY_CTX_set_mac_key() macro can be used with any of the algorithms
+supported by the L<EVP_PKEY_new_raw_private_key(3)> function.
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,
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_dh_pad() macro sets the DH padding mode. If B<pad> is
+1 the shared secret is padded with zeroes up to the size of the DH prime B<p>.
+If B<pad> is zero (the default) then no padding is performed.
+
+EVP_PKEY_CTX_set_dh_nid() sets the DH parameters to values corresponding to
+B<nid>. The B<nid> parameter must be B<NID_ffdhe2048>, B<NID_ffdhe3072>,
+B<NID_ffdhe4096>, B<NID_ffdhe6144> or B<NID_ffdhe8192>. This macro can be
+called during parameter or key generation.
+
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.
