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?

@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".

@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 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.
