Web9 Sep 2014 · The basic idea of a substitution cipher is a simple one: take one letter in your message, let’s say ‘A’, and replace it with a different letter, such as ‘E’. Sounds familiar? … WebAES is a symmetric encryption method, meaning it uses the same key to encrypt data as it does to decrypt data. It also applies multiple rounds of the SPN (substitution permutation network) algorithm to encrypt data. The sheer number of encryption rounds that AES utilises are what makes it so impenetrable. There are three possible lengths of AES ...
