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.

       Note that, unlike gnutls_pkcs7_verify() this function does not verify the
       key purpose of the signer. It is expected for the caller to verify the
       intended purpose of the signer -e.g., via
       gnutls_x509_crt_get_key_purpose_oid(), or
       gnutls_x509_crt_check_key_purpose().

       Note also, that since GnuTLS 3.5.6 this function introduces checks in the
       end certificate ( signer ), including time checks and key usage checks.

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
