A list of useful rc4 and base64 functions.
npm install npm-rc4rc4 and base64 functions for Node.js and Browser.\
atob() and btoa(); this guarantee a proper base64 conversion between different languages like PHP with base64_encode and base64_decode.
bash
$ npm install npm-rc4
`
Node.js
`js
const {
rc4,
rc4Base64Encrypt,
rc4Base64Decrypt,
rc4Base64,
isBase64,
base64encode,
base64decode
} = require('npm-rc4');
`
ES6
`js
