Specky Endecode

Installation

npm i specky-endecode

Usage

const endecode = require('specky-endecode');
const text = 'It will never get encoded.';  // dead meme
const encoded = endecode(text);             // K( ).€k IY"gg P%1 Rka#0;-T
const decoded = endecode(encoded);          // It will never get encoded.

const options = {
    characters: 'abcd', // has to be an even number of characters
    whitespaces: '\s\r\n',
    log: true,
};

const withOptions = endecode('abacaba', options); // bcdabcb

Notes

The supported characters by default are the following:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789()[]{}!\"§$%&/=?`´*-+<>\\#'_^°~,.;:|@€

Flaws

This system obviously has flaws, here are some I found:

• a character can't get output as itself
• if a character gets swapped with it's output, the characters after that won't get shuffled
• newlines and spaces don't change the outcome
