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  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.
