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 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

DESCRIPTION
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.

RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.

SINCE
3.4.2
