=pod =head1 NAME EVP_PKEY_get_default_digest_nid - get default signature digest =head1 SYNOPSIS #include <openssl/evp.h> int EVP_PKEY_get_default_digest_nid(EVP_PKEY *pkey, int *pnid); =head1 DESCRIPTION The EVP_PKEY_get_default_digest_nid() function sets B<pnid> to the default message digest NID for the public key signature operations associated with key B<pkey>. =head1 NOTES For all current standard OpenSSL public key algorithms SHA1 is returned. =head1 RETURN VALUES The EVP_PKEY_get_default_digest_nid() function returns 1 if the message digest is advisory (that is other digests can be used) and 2 if it is mandatory (other digests can not be used). It returns 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. =head1 SEE ALSO L<EVP_PKEY_CTX_new(3)|EVP_PKEY_CTX_new(3)>, L<EVP_PKEY_sign(3)|EVP_PKEY_sign(3)>, L<EVP_PKEY_verify(3)|EVP_PKEY_verify(3)>, L<EVP_PKEY_verify_recover(3)|EVP_PKEY_verify_recover(3)>, =head1 HISTORY This function was first added to OpenSSL 1.0.0. =cut
