I have a question for a assignment that is due tomorrow morning that I can't figure out. I'd appreciate any help. Here goes: It was stated that the inclusion of the salt in the UNIX password scheme increases the difficulty of guessing by a factor of 4096. But the salt may be stored in plaintext in the same entry as the corresponding ciphertext password. Therefore, those two characters may be known to the attacker and need not be guessed. Why then is it asserted that the salt increases security? I have a feeling this is easy but I can't figure it out. Can anyone help?
