3.0.0 is a habit from pre-3.0 OpenSSL, which doesn't make sense with the new version scheme. Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/9376)

=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.
