Ok, back to the real topic. The essence is that for key (or password generation) you'll want a cryptographically strong generator. See http://en.wikipedia.org/wiki/Cryptographically_secure_pseudorandom_number_generator Why? Because otherwise attackers might e.g. compute your password based on the seed you could have used. Especially time-based seeds are bad in this respect. But even if you have a good seed, attackers can compute earlier or later password based on one or more passwords they know you have generated. -Otto
