| 33 | int PKCS7_ISSUER_AND_SERIAL_digest(PKCS7_ISSUER_AND_SERIAL *data, |
| 34 | const EVP_MD *type, unsigned char *md, |
| 35 | unsigned int *len); |
| 36 | |
| 37 | =head1 DESCRIPTION |
| 38 | |
| 39 | X509_pubkey_digest() returns a digest of the DER representation of the public |
| 40 | key in the specified X509 B<data> object. |
| 41 | All other functions described here return a digest of the DER representation |
| 42 | of their entire B<data> objects. |
| 43 | |
| 44 | The B<type> parameter specifies the digest to |
| 45 | be used, such as EVP_sha1(). The B<md> is a pointer to the buffer where the |
| 46 | digest will be copied and is assumed to be large enough; the constant |
| 47 | B<EVP_MAX_MD_SIZE> is suggested. The B<len> parameter, if not NULL, points |
| 48 | to a place where the digest size will be stored. |
| 49 | |
| 50 | =head1 RETURN VALUES |
| 51 | |
| 52 | All functions described here return 1 for success and 0 for failure. |
