👉 Risuses is a term used in the field of computer science and cryptography to refer to a specific type of encryption algorithm. It was first introduced by the Swiss mathematician, Hans Schneier, in his 1987 book "The Art of Computer Programming" as an alternative to the more common Caesar cipher. Risuses is characterized by its use of a key for decryption and a modulus for encryption, which results in a unique sequence of characters that can be used to decrypt any
