+=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. |
