Caesar cipher

In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be replaced by A, E would become B, and so on. The method is named after Julius Caesar, who used it in his private correspondence.

A game in Python (RPS)

The Basic Rules of RPS ( Rock, Paper or Scissors)

Despite its underlying complexity, the game’s rules are straightforward. Players deliver hand signals representing rock, paper, or scissors, with the outcome determined by these three rules:

1) Rock wins against scissors.
2) Scissors win against paper.
3) Paper wins against rock.
