comment two public keys with same passphrase insecure? | can two hashes be compared?
@mikeazo: At best the attacker gets a two for one, but since the user withdraws the first key it gets the attacker no where. If both keys use a secure hash algorithm then they are both as secure for reversing to the passphrase.

comment How to require two keyholders to decrypt a document?
They are "trusted" but it is a matter of timing and liability. If they cannot decrypt it until a specific time, then they are not liable for it.

Who knew XOR would be the "best practice" answer to a question on Cryptography.

I asked him if he was referring to the initialization vector, and that is what it sounds like from that explanation. Thanks!
