NAME
gnutls_pkcs7_sign - API function
SYNOPSIS
#include <gnutls/pkcs7.h>
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);
ARGUMENTS
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 embed-
ded
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
DESCRIPTION
This function will add a signature in the provided PKCS 7 structure for
the provided data. Multiple signatures can be made with different sign-
ers.
The available flags are: GNUTLS_PKCS7_EMBED_DATA, GNUTLS_PKCS7_IN-
CLUDE_TIME, GNUTLS_PKCS7_INCLUDE_CERT, and GNUTLS_PKCS7_WRITE_SPKI. They
are explained in the gnutls_pkcs7_sign_flags definition.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error
value.
