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.
