+

+
+ #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.
+
+=head1 SEE ALSO
+
+L<EVP_DigestSignInit_ex(3)>,
+

+
+The EVP_PKEY_digestsign_supports_digest() function was added in OpenSSL 3.0.

-=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.
