>(1) a hash is always the same length (eg md5 hash = 16 bytes or 32 hex chars)
>(2) encryption without block cyphering (eg rc4) : the lengths will vary
>(3) If you use block ciphering, the lengths will vary depending on the length of the password, but all lengths will be a multiple of the block

Let you guess the password?
