Create a secure password using /dev/urandom and whirlpool

/dev/urandom relies on operator input to set the random seed. By itself, this may not contain enough random bits to produce high entropy output, especially if the system was recently restarted. Therefore, key stretching through a hash reduces the risk of using low-entropy output as a security key.
