In turn, this key contains the âcypherâ, which dictates how the data encryption occurs. What is a cypher? A cypher is an algorithm for performing encryption and decryption â a series of steps to follow as a procedure. There are many different ways in which plaintext can be encrypted, but essentially there are two main processes used: symmetric key algorithms and asymmetric key algorithms . Algorithms .
