Hi Oli, I've uploaded a new patch to https://issues.apache.org/jira/browse/HARMONY-6627 that gets a bit further with the handshake. Currently I can get back the initial handshake data from the client, get the server to accept this and then request a certificate from the client but then the testcase fails to get further. I've left my debug code in, so it's a bit untidy, but may be of help to you too. I'm going to continue working on the wrap/unwrap methods - I need to think more about the different conditions to construct the return object, which is a combination of an engine state, handshake state and the number of bytes consumed and produced. There's also some other methods that will require native implementations - closeInbound, closeOutbound.
Best wishes, Cath
