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.
