Using Python’s string translation functionality I was able to make a more generic implementation, allowing you to specify the position length. Latin alphabet encoding is also present with the five position length invariant. Posted by. ROT13 is an example of the Caesar cipher. We could have instead assigned this function to a variable (say ‘rot13’) and call at will. It has been described as the "Usenet equivalent printing an answer to a quiz upside down" as it provides virtually no cryptographic security. Say we would like to use ROT5 for number encoding, this would require an individual implementation. Kata. I would like to note that a separate decode implementation is required (-N), as unlike ROT13 the encode algorithm is not it’s own inverse. Rot13. Substitutions of this kind rely on the invariant - replace each plain-text letter by the letter some fixed number of positions across the alphabet. The recipient is then able to successfully decode the encoded message if they are aware of the chosen position system. Ciphers. ROT13 (aka. Sum of Pairs.js .

Explanation of ROT13 Algorithm ROT13 cipher refers to the abbreviated form Rotate by 13 places. Voilà alors j'ai eu l'idée, rot13 marchant que sur les caractères, il fallait donc encrypter les caractères, alors très simple puisque 13+13=26 donc A + 26 = N + 26 (voilà comment marche rot13), il suffit de faire 1 + 5 = 6 + 5 (en gros hein, parce qu'ensuite on fout un modulo).
