scrambler

Pure JavaScript/TypeScript implementation of simple substitution ciphers: ROT13, ROT47, and Zenit Polar.

Each cipher rotates by half its alphabet, so scramble and descramble are the same operation applied twice.

API

import { rot13, rot47, zenitPolar } from '@linkrj/scrambler';

rot13.scramble('Hello');      // 'Uryyb'
rot13.descramble('Uryyb');    // 'Hello'

rot47.scramble('hello');      // '96==@'
zenitPolar.scramble('message'); // 'mossigo'

CLI

scrambler <cipher> <message>

$ scrambler rot13 "Hello World"
Uryyb Jbeyq
$ scrambler rot13 "Uryyb Jbeyq"
Hello World

Ciphers: rot13, rot47, zenitPolar.
