comment Is this really the correct way to do an IND-CPA test?
@e-sushi I'm the author of that article. It was not meant to be a really precise definition, just to introduce the concept to beginners (that's also why I did not talk about adaptive CPA). Anyhow, thanks for pointing this out, I fixed the article to mention both messages have to be the same length. Note that sending different plaintexts to encrypt and observing the length of resulting ciphertexts is how the CRIME attack works :)

comment What are the practical differences between 256-bit, 192-bit, and 128-bit AES encryption?
The choice of key length should also be based on time: for how much time must your data be safe? (taking into account cheaper and more powerful computers as time passes, and eventual future breaks in AES).

SSL can use Diffie-Hellman to generate the session key
