comment Why should I use Authenticated Encryption instead of just encryption?
I think AE also provides integrity (en.wikipedia.org/wiki/Authenticated_encryption) so might want to add that as well..

Thanks. This was something I was searching for. If you could just post it as answer I would gladly accept it.

I assume that B in this case means BBB9, right?

@rath - So, is there anyway to determine randomness?

@owlstead - +1 Thanks for the info. That is something I didn't really know.

comment How to choose keys for a block cipher?
@Thomas - I know that functions like PBKDF2 are used to derive keys from Passwords. However, I didn't know that these functions are also used to derive keys for the block cipher. I always thought that these keys were hard coded/pre-programmed in to the circuit. Are you asking how those keys are generated e.g. how they are derived from passwords for instance and **so on** ? (This could be a separate question but) What are the other methods to derive keys other than passwords?
