In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]

The basis of the method that the Heath Robinson machine implemented was Bill Tutte's "1+2 technique". [10] This involved examining the first two of the five impulses [11] of the characters of the message on the ciphertext tape and combining them with the first two impulses of part of the key as generated by the wheels of the Lorenz machine.
