gnutls_pkcs7_sign - API function
int gnutls_pkcs7_sign(gnutls_pkcs7_t pkcs7, gnutls_x509_crt_t signer, gnutls_privkey_t signer_key, const gnutls_datum_t * data, gnutls_pkcs7_attrs_t signed_attrs, gnutls_pkcs7_attrs_t unsigned_attrs, gnutls_digest_algorithm_t dig, unsigned flags);
- gnutls_pkcs7_t pkcs7
- should contain a gnutls_pkcs7_t type
- gnutls_x509_crt_t signer
- the certificate to sign the structure
- gnutls_privkey_t signer_key
- the key to sign the structure
- const gnutls_datum_t * data
- The data to be signed or NULL if the data are already embedded
- gnutls_pkcs7_attrs_t signed_attrs
- Any additional attributes to be included in the signed ones (or NULL)
- gnutls_pkcs7_attrs_t unsigned_attrs
- Any additional attributes to be included in the unsigned ones (or NULL)
- gnutls_digest_algorithm_t dig
- The digest algorithm to use for signing
- unsigned flags
- Should be zero or one of GNUTLS_PKCS7 flags
This function will add a signature in the provided PKCS 7 structure for the provided data. Multiple signatures can be made with different signers.
The available flags are: GNUTLS_PKCS7_EMBED_DATA, GNUTLS_PKCS7_INCLUDE_TIME, GNUTLS_PKCS7_INCLUDE_CERT, and GNUTLS_PKCS7_WRITE_SPKI. They are explained in the gnutls_pkcs7_sign_flags definition.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
