"In cryptography, key size, key length, or key space refer to the number of bits in a key used by a cryptographic algorithm (such as a cipher). Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all … See more Keys are used to control the operation of a cipher so that only the correct key can convert encrypted text (ciphertext) to plaintext.
