>> This PR updates the CertificateBuilder with a new method that creates a new instance with common fields (subject name, public key, serial number, validity, and key uses) filled-in. One test, IPIdentities.java, is updated to show how the method can be used to create various certificates. I attached screenshots that compare the old hard-coded certificates (left) with the new generated certificates.
