I've implemented both the Salsa20 and Rabbit ciphers in C#. My implementation is for academic purposes and I've tested both of them against the test vectors. I implemented a system that encrypts a file twice, once with each form of encryption. I want to find out what kind of analysis I can perform to test their various aspects such as speed, security, performance etc.
While I understand that some of you might think this is not a good idea, I am doing it purely for academic purposes and this will never be used in a real world system.
I would like to perform some tests where I compare the plaintext and ciphertext and note any observations. I have no experience or idea regarding where to start or what to do. Though I do not need to go into depth on this topic as my professor doesn't require it.
