NAME

       gnutls_pkcs7_verify_direct - API function

SYNOPSIS

       #include <gnutls/pkcs7.h>

       int  gnutls_pkcs7_verify_direct(gnutls_pkcs7_t  pkcs7,  gnutls_x509_crt_t  signer,  unsigned  idx,  const
       gnutls_datum_t * data, unsigned flags);

ARGUMENTS

       gnutls_pkcs7_t pkcs7
                   should contain a gnutls_pkcs7_t type

       gnutls_x509_crt_t signer
                   the certificate believed to have signed the structure

       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 error value. A verification error
       results  to  a  GNUTLS_E_PK_SIG_VERIFY_FAILED  and  the  lack  of  encapsulated  data  to  verify  to   a
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE.

SINCE

       3.4.2
