Diffie Hellman Exchange

A simple but fastidious attempt to write a diffie-hellman key exchange utility that could be used as transport upgraders in distributed systems.

If you are trying to use this in a traditional n tier computing environment, you are crazy and use well tested default secure channels that are available with every library on the face of earth.

All the keys are Serializable allowing you to transport them as you wish. Transport is out of scope for this project.

Id reconciliation

This handshake creates a new Elliptic curve key(based on the curve you specify). If you want to use this with some other systems with different identity mechanisms,

You may want to add a signature whenever you are transferring this public key. Use your default curve to add a sign to the public key you would be transferring.

Wire support

Usually only Public keys are transferred, so the library provides marshal and unmarshal support for them.

Symmetric Encryption - AES GCM

After a common secret key is agreed upon, the lib also provides some AES utils for encrypting and decrypting any random content you want.

Usage

Refer the tests for usage. You may also want to refer the interface for clarity on the methods supported.
