+=head1 NAME
+
+EVP_PKEY_supports_digest_nid - indicate support for signature digest
+
+=head1 SYNOPSIS
+
+ #include <openssl/evp.h>
+ int EVP_PKEY_supports_digest_nid(EVP_PKEY *pkey, int nid);
+
+=head1 DESCRIPTION
+
+The EVP_PKEY_supports_digest_nid() function queries whether the message digest
+NID B<nid> is supported for public key signature operations associated with key
+B<pkey>.
+
+=head1 NOTES
+
+If the EVP_PKEY implementation does not explicitly support this method, but
+L<EVP_PKEY_get_default_digest_nid(3)> returns a mandatory digest result, then
+only that mandatory digest will be supported.
+
+=head1 RETURN VALUES
+
+The EVP_PKEY_supports_digest_nid() function returns 1 if the message digest
+algorithm identified by B<nid> can be used for public key signature operations
+associated with key B<pkey> and 0 if it cannot be used. It returns a negative
+value for failure. In particular a return value of -2 indicates the query
+operation is not supported by the public key algorithm.

+For all of the functions below that set the supported groups there must be at

 SSL_CTX_set1_groups() sets the supported groups for B<ctx> to B<glistlen>
