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