=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. |
