                                                   throws TSPValidationException
        Fetches the signature time-stamp attributes from a SignerInformation object. Checks that the MessageImprint for each time-stamp matches the signature field. (see RFC 3161 Appendix A).
        Parameters:
        signerInfo - a SignerInformation to search for time-stamps
        digCalcProvider - provider for digest calculators
        Returns:
        a collection of TimeStampToken objects
        Throws:
        TSPValidationException

      • validateCertificate

        public static void validateCertificate​(X509CertificateHolder cert)
                                throws TSPValidationException
        Validate the passed in certificate as being of the correct type to be used for time stamping. To be valid it must have an ExtendedKeyUsage extension which has a key purpose identifier of id-kp-timeStamping.
        Parameters:
        cert - the certificate of interest.
        Throws:
        TSPValidationException - if the certificate fails on one of the check points.
