Validating x509 certificates vb net united water fluoridating water
To quote Open SSL: extension dictates if a certificate is a CA (can sign others) or not.
If it is, it also says how many CAs can follow it before a leaf certificate.
We need to first create the X.509 certificates we will be using in our scenario to check the certificate revoke functionality.
We will use the Open SSL command line tool to create these certificates.
Oracle Web Logic Server 12c's Java Secure Socket Extension (JSSE) implementation supports X.509 Certificate Revocation (CR) checking using Online Certificate Status Protocol (OCSP) protocol, which checks a certificate's revocation status as part of the Secure Sockets Layer (SSL) certificate path validation process.
CR checking improves the security of certificate usage by ensuring that received certificates have not been revoked by the issuing certificate authority.
Although this article focuses on inbound OCSP validation using OCSP, Oracle Web Logic Server 12c also supports outbound OCSP validation.

explanation: x509 certificate is an evolving standard, exactly like TLS, through extensions.
To preserve backward compatibility, not being able to parse an extension is often considered OK, that is unless the extension is considered critical (important).
