42 X509_digest_sig() calculates a digest of the given certificate
43 using the same hash algorithm as in its signature.
45 X509_pubkey_digest() returns a digest of the DER representation of the public
46 key in the specified X509 B<data> object.
48 All other functions described here return a digest of the DER representation
49 of their entire B<data> objects.
51 The B<type> parameter specifies the digest to
52 be used, such as EVP_sha1(). The B<md> is a pointer to the buffer where the
53 digest will be copied and is assumed to be large enough; the constant
54 B<EVP_MAX_MD_SIZE> is suggested. The B<len> parameter, if not NULL, points
55 to a place where the digest size will be stored.
59 X509_digest_sig() returns an ASN1_OCTET_STRING on success, else NULL.
61 All other functions described here return 1 for success and 0 for failure.
69 The X509_digest_sig() function was added in OpenSSL 3.0.
