|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/evp.h>
|
|
int EVP_PKEY_digestsign_supports_digest(EVP_PKEY *pkey, OSSL_LIB_CTX *libctx,
|
|
const char *name, const char *propq);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The EVP_PKEY_digestsign_supports_digest() function queries whether the message
|
|
digest I<name> is supported for public key signature operations associated with
|
|
key I<pkey>. The query is done within an optional library context I<libctx> and
|
|
with an optional property query I<propq>.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
The EVP_PKEY_digestsign_supports_digest() function returns 1 if the message
|
|
digest algorithm identified by I<name> can be used for public key signature
|
|
operations associated with key I<pkey> and 0 if it cannot be used. It returns
|
|
a negative value for failure.
