comment Why, or when, to use an Initialization Vector?
Is there any attack to be had in my example; where i leave the IV always at zero?

comment Why, or when, to use an Initialization Vector?
@PaĆ­loEbermann In that case it would be whatever the "default" is; which is documented to be all zero's. But if AES doesn't support an IV, then i guess my IV is "undefined".

comment Is it fair to assume that SHA1 collisions won't occur on a set of <100k strings
@owlstead "Is it fair to assume that SHA1 collisions won't occur on a set of <100k strings" Yes, it is fair to assume that SHA1 collisions won't occur on a set of <100k strings.

comment Academic papers on GPU password cracking?
@Ninefingers i saw the title, and wondered what the answer was - only to find the question closed. The question is clear, and it is useful. You closed it, so you win; i just disagree.

comment Academic papers on GPU password cracking?
@Ninefingers It's not "please list". It's "are there any": a true/false answer. Either there are or there are not. For example, "Has anyone ever found two messages that collide in SHA1"; i'm not asking for a comprehensive list of all messages - i'm asking if it has ever happened.

comment Time Capsule cryptography?
The downside of having a time capsule that you don't want opened until 20 years from now: is that you must spend 18 years encrypting the puzzle. Considering Moore's law it will then take 2 years for the public to decrypt it. Total: 20 years.
