gnutls_pkcs7_verify_direct(3) gnutls gnutls_pkcs7_verify_direct(3)
NAME
gnutls_pkcs7_verify_direct - API function
SYNOPSIS
#include <gnutls/pkcs7.h>
gnutls_pkcs7_verify_direct(3) 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_VER-
IFY_FAILED and the lack of encapsulated data to verify to a
GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE.
SINCE
3.4.2
