# 40-bit encryption

40-bit encryption refers to a (now broken) key size of forty bits, or five bytes, for symmetric encryption; this represents a relatively low level of security. A forty bit length corresponds to a total of 240 possible keys. Although this is a large number in human terms (about a trillion), it is possible to break this degree of encryption using a moderate amount of computing power in a brute-force attack, i.e., trying out each possible key in turn. (Wikipedia).

Affine Cipher - Decryption (Known Plaintext Attack)

In this video I talk about ways to decrypt the Affine Cipher when the key is NOT known. Specifically, I go over an example of the known plaintext attack. 3^(-1) = 9 (mod 26) math worked out (Euclidean Algorithm): 1. Forwards: 26 = 3(8) + 2 3 = 2(1) + 1 2. Backwords: 1 = 3 -
