NAME         top

       gnutls_pkcs7_verify - API function

SYNOPSIS         top

       #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         top

       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         top

       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         top

       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
