Hi Tony, The motivation was mostly about reading PEM keys and certificates generated somewhere else. This is common practice in enterprise environments I work in. Because corporate key material is subject to centralized key management, including generation, backup and rollover. PEM is the format most software products can handle. For Java applications, having a PEM KeyStore would reduce the often required additional step of converting PEM key and certificate in a Java Keystore/PKCS#12. Even truststores handling is easier with individual PEM certificates instead of a single PKCS#12 Truststore. Adding or deleting a single file instead of replacing the complete PKCS#12 store is less error prone and cleaner to track in version control. The additional benefit of a MAC in PKCS#12 adds little to no security in most cases. And being text based, PEM is more version control friendly than binary PKCS#12.
But to enable sound support of PEM, I also implemented writing PEM keys and certificates. This way, one can use the JDK keytool to generate key and certificate signing requests in PEM format. Getting the certificate from the CA in PEM, one can use PEM throughout the process. Do you have any links or documentation on the PEM API JEP that you mentioned?
