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
