About ROT13 & Caesar Cipher

                        
                            
                        
                    

                    

                        
ROT13 is a simple substitution cipher that replaces each letter with the
                            letter 13 positions after it. Since there are 26 letters, applying ROT13 twice returns the
                            original text.

                        
Caesar cipher is the generalization where you can shift by any
                            amount. Named after Julius Caesar who used it for military communications.
