WebIn general, the number of possible passwords is S k, where S is the alphabet size, and k is the password length. It is easy to see that a password, corresponding to a 128-bit key, should satisfy the equation. S k = 2 128. or, using logarithms. k log S = 128 log 2. hence. k = 128 log 2 / log S. If the alphabet contains more symbols, S should be ... WebJul 26, 2024 · Passwords and Cryptographic Hash Functions A database saves user passwords in a manner similar to a rainbow table.
