When the stream of data used as key is truly random and used only once, it is called a one-time pad. A widely used implementation of the Vernam cipher is RC4.

This is symbolised by ⊕ and is represented by the following "truth table", where + represents "true" and − represents "false". Other names for this function are: Not equal (NEQ), modulo 2 addition (without 'carry') and modul… forch nzIn cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is not smaller than the message being sent. In this technique, a plaintext is paired with a random secret key (also referred to as a one-time pad).
