Base64 encode decode with key in pure javascript/typescript.
Many developers want to encode and decode base64 with privacy and don't want others to know of the many online base64 encode decode tools.
- Encode decode with key.
- Dynamic Encode decode.
- Normal Encode decode (without key).
- Generate string random (bonus).
Using npm:
$ npm install base64kUsing yarn:
$ yarn add base64k- Initialize base64k
//esm or ts
import base64k from "base64k";

const text = "mysimpletest";
const key = "mykey";
const encode = base64k.encode(text, key);
console.log(encode);
//console.log : AAAYDBQdFQ4RHB4N
const decode = base64k.decode(encode, key);
console.log(decode);
//console.log : mysimpletest
...- Dynamic encode and decode (generate random encode with the same string after decode.)
...
const text = "mysimpletest%&example";
const dyn_encode_1 = base64k.dynEncode(text);
