    • ocsps

      protected List<IBasicOCSPResp> ocsps
      Deprecated.
      The list of IBasicOCSPResp OCSP response wrappers.

  • Constructor Details

    • OCSPVerifier

      public OCSPVerifier (CertificateVerifier verifier, List<IBasicOCSPResp> ocsps)
      Deprecated.
      Creates an OCSPVerifier instance.
      Parameters:
      verifier - the next verifier in the chain
      ocsps - a list of IBasicOCSPResp OCSP response wrappers for the certificate verification

  • Method Details

    • setOcspClient

      public void setOcspClient (IOcspClient ocspClient)
      Deprecated.
      Sets OCSP client to provide OCSP responses for verifying of the OCSP signer's certificate (an Authorized Responder). Also, should be used in case responder's certificate doesn't have any method of revocation checking.

      See RFC6960 4.2.2.2.1. Revocation Checking of an Authorized Responder.

      Optional. Default one is OcspClientBouncyCastle.

      Parameters:
      ocspClient - IOcspClient to provide an Authorized Responder revocation data.

    • setCrlClient

      public void setCrlClient (ICrlClient crlClient)
      Deprecated.
      Sets CRL client to provide CRL responses for verifying of the OCSP signer's certificate (an Authorized Responder) that also should be used in case responder's certificate doesn't have any method of revocation checking.

      See RFC6960 4.2.2.2.1. Revocation Checking of an Authorized Responder.

      Optional. Default one is CrlClientOnline.

      Parameters:
      crlClient - ICrlClient to provide an Authorized Responder revocation data.

    • verify

      public List<VerificationOK> verify (X509Certificate signCert, X509Certificate issuerCert, Date signDate) throws GeneralSecurityException
      Deprecated.
      Verifies if a valid OCSP response is found for the certificate. If this method returns false, it doesn't mean the certificate isn't valid. It means we couldn't verify it against any OCSP response that was available.
      Overrides:
      verify in class RootStoreVerifier
      Parameters:
      signCert - the certificate that needs to be checked
      issuerCert - issuer of the certificate to be checked
      signDate - the date the certificate needs to be valid
      Returns:
      a list of VerificationOK objects. The list will be empty if the certificate couldn't be verified.
      Throws:
      GeneralSecurityException - thrown if the certificate has expired, isn't valid yet, or if an exception has been thrown in Certificate#verify.

    • verify

      public boolean verify (IBasicOCSPResp ocspResp, X509Certificate signCert, X509Certificate issuerCert, Date signDate) throws GeneralSecurityException
      Deprecated.
      Verifies a certificate against a single OCSP response.
      Parameters:
      ocspResp - IBasicOCSPResp the OCSP response wrapper for a certificate verification
      signCert - the certificate that needs to be checked
      issuerCert - the certificate that issued signCert – immediate parent. This certificate is considered trusted and valid by this method.
      signDate - sign date (or the date the certificate needs to be valid)
      Returns:
      true in case check is successful, false otherwise.
      Throws:
      GeneralSecurityException - if OCSP response verification cannot be done or failed.

    • isValidResponse

      public void isValidResponse (IBasicOCSPResp ocspResp, X509Certificate issuerCert, Date signDate) throws GeneralSecurityException
      Deprecated.
      Verifies if an OCSP response is genuine. If it doesn't verify against the issuer certificate and response's certificates, it may verify using a trusted anchor or cert.
      Parameters:
      ocspResp - IBasicOCSPResp the OCSP response wrapper
      issuerCert - the issuer certificate. This certificate is considered trusted and valid by this method.
      signDate - sign date for backwards compatibility
      Throws:
      GeneralSecurityException - if OCSP response verification cannot be done or failed.

    • isSignatureValid

      public boolean isSignatureValid (IBasicOCSPResp ocspResp, Certificate responderCert)
      Deprecated.
      Checks if an OCSP response is genuine.
      Parameters:
      ocspResp - IBasicOCSPResp the OCSP response wrapper
      responderCert - the responder certificate
      Returns:
      true if the OCSP response verifies against the responder certificate.

    • getOcspResponse

      public IBasicOCSPResp getOcspResponse (X509Certificate signCert, X509Certificate issuerCert)
      Deprecated.
      Gets an OCSP response online and returns it without further checking.
      Parameters:
      signCert - the signing certificate
      issuerCert - the issuer certificate
      Returns:
      IBasicOCSPResp an OCSP response wrapper.
