Hello, As an expected task for GSOC (discussed on IRC) I worked on the JCA implementation for encryption. Here is what I have done-
1. Created JCACipher implements Block Cipher. 2. Added negtype = 8 3. For negtype = 8 use new JCACipher object instead of new Rijndael object 4. Changed other methods in FNPPacketMangler to accept the new new link type I needed to go through this paper to understand what JFK was all about http://www.wisdom.weizmann.ac.il/~reingold/publications/jfk-tissec.pdf What I am not sure of is that the method computeJFKsharedKey is used by my cipher class too to generate the SecretKey required, but should I use the JCA key generator to do so? That should not be a problem. I am not sure if this is what nextgens had in mind. But currently I have tested two nodes running in darknet mode, and they were able to connect to each other and send messages. Also I used the debugger to see if negtype = 8 was present. I also ran another old node for which negtype=7 worked normally (backward compatible). I hope this is what you were expecting. Here is the patch, but I suppose you want me to send a pull request? I ll do that too. Thank you, Chetan
