NAME
       gnutls_pkcs7_verify - API function

SYNOPSIS
       #include	<gnutls/pkcs7.h>

       int  gnutls_pkcs7_verify(gnutls_pkcs7_t pkcs7, gnutls_x509_trust_list_t
       tl, gnutls_typed_vdata_st * vdata, unsigned  int	 vdata_size,  unsigned
       idx, const gnutls_datum_t * data, unsigned flags);

ARGUMENTS
       gnutls_pkcs7_t pkcs7
		   should contain a gnutls_pkcs7_t type

       gnutls_x509_trust_list_t	tl
		   A list of trusted certificates

       gnutls_typed_vdata_st * vdata
		   an array of typed data

       unsigned	int vdata_size
		   the number of data elements

       unsigned	idx
		   the index of	the signature info to check

       const gnutls_datum_t * data
		   The data to be verified or NULL

       unsigned	flags
		   Zero	or an OR list of gnutls_certificate_verify_flags

DESCRIPTION
       This  function  will  verify  the  provided  data against the signature
       present in the SignedData of the	PKCS 7 structure. If the data provided
       are NULL	then the data in the encapsulatedContent field	will  be  used
       instead.

RETURNS
       On  success, GNUTLS_E_SUCCESS (0) is returned, otherwise	a negative er-
       ror value. A  verification  error  results  to  a  GNUTLS_E_PK_SIG_VER-
       IFY_FAILED   and	  the  lack  of	 encapsulated  data  to	 verify	 to  a
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE.

SINCE
       3.4.2
