=head1 DESCRIPTION
|
|
|
|
X509_pubkey_digest() returns a digest of the DER representation of the public
|
|
key in the specified X509 B<data> object.
|
|
All other functions described here return a digest of the DER representation
|
|
of their entire B<data> objects.
|
|
|
|
The B<type> parameter specifies the digest to
|
|
be used, such as EVP_sha1(). The B<md> is a pointer to the buffer where the
|
|
digest will be copied and is assumed to be large enough; the constant
|
|
B<EVP_MAX_MD_SIZE> is suggested. The B<len> parameter, if not NULL, points
|
|
to a place where the digest size will be stored.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
All functions described here return 1 for success and 0 for failure.
