Binary Data Search and Compare

Typically, you would read the "publicKey" attribute to read the
certificate into a bbyte[]

Then use the java.security.cert.X509Certificate api would be used to
read the various certificate parameters.

You could also write your own javax.net.ssl.X509TrustManager to
determine if the certificate is valid or not by comparing the various
certificate parameters.
