Thanks for clarifying the JSSE issue. It's a shame that JSSE can't make use of available JCE algorithms. I've just been trying to establish the limits of the Java 7 implementation, and I think I understand that now. Yes, the ECDHE ciphersuites are definitely the choice for strongest secrecy wi

Hi the JSSE Reference Guide defines which possibilities for anyone implementing a JSSE provider (let's call it an API if you want). Oracle's provider only implements a part of this API, misleading you to believe SHA384 is available when it's unfortunately not. About Bouncy Castle, I believe they

Thanks, Aurélien. I'd seen the SHA384 versions listed in the JSSE Cipher Suite Names and thought they were available: http://docs.oracle.com/javase/7/docs/technotes/guides/security/StandardNames.html#ciphersuites I was really hoping to use one of the GCM suites, but I gather those are not offi

According to RFC 5246 Appendix C (TLS 1.2), there is no SHA384. See : http://www.ietf.org/rfc/rfc5246.txt The JSSE Reference Guide also doesn't talk about this SHA384 as an implementation requirement. See : http://docs.oracle.com/javase/7/docs/technotes/guides/security/StandardNames.html#impl Thi
