int gnutls_x509_crt_verify_data2(gnutls_x509_crt_t crt, gnutls_sign_algorithm_t algo, unsigned int flags, const gnutls_datum_t * data, const gnutls_datum_t * signature);
- gnutls_x509_crt_t crt
Holds the certificate to verify with
- gnutls_sign_algorithm_t algo
The signature algorithm used
- unsigned int flags
Zero or an OR list of gnutls_certificate_verify_flags
- const gnutls_datum_t * data
holds the signed data
- const gnutls_datum_t * signature
contains the signature
This function will verify the given signed data, using the parameters from the certificate.
In case of a verification failure GNUTLS_E_PK_SIG_VERIFY_FAILED is returned, GNUTLS_E_EXPIRED or GNUTLS_E_NOT_YET_ACTIVATED on expired or not yet activated certificate and zero or positive code on success.
Note that since GnuTLS 3.5.6 this function introduces checks in the end certificate ( crt ), including time checks and key usage checks.
