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_at-
     trs_t  signed_attrs, gnutls_pkcs7_attrs_t unsigned_attrs, gnutls_digest_al-
     gorithm_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_IN-
     CLUDE_TIME, GNUTLS_PKCS7_INCLUDE_CERT,  and  GNUTLS_PKCS7_WRITE_SPKI.  They
     are explained in the gnutls_pkcs7_sign_flags definition.
