gnutls_x509_crt_verify_data2 - API function
#include <gnutls/x509.h> 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.
