SecureBlackbox 16: How check the revocation status of a certificate

You can check the revocation status in the following ways:

• Obtaining CRL lists and checking if the certificate is listed there
• Sending an OCSP request to the server to check the same

SecureBlackbox offers the OCSP client component for sending OCSP requests and the CRL management component for dealing with CRLs. Also, if you use the TElX509CertificateValidator class to validate certificates, this class checks the revocation status automatically (unless you turn off such checks).
