# npm-rc4

[![NPM version](https://img.shields.io/npm/v/npm-rc4.svg?style=flat)](https://www.npmjs.com/package/npm-rc4)

A list of useful `rc4` and `base64` functions for [Node.js](https://nodejs.org) and Browser.\

Differently from the previous version, it doesn't use `atob()` and `btoa()`; this guarantee a proper base64 conversion between different languages like PHP with `base64_encode` and `base64_decode`.

![npm-rc4](https://user-images.githubusercontent.com/6490641/82446373-7401b280-9a9e-11ea-835b-7f6a75c55f65.gif "npm-rc4")

## Installing

Using npm:

```bash

$ npm install npm-rc4

```

## Node.js

```js

const {

	rc4,

	rc4Base64Encrypt,

	rc4Base64Decrypt,

	rc4Base64,

	isBase64,

	base64encode, 

	base64decode

} = require('npm-rc4');

```

## ES6

```js

import {

	rc4,

	rc4Base64Encrypt,

	rc4Base64Decrypt,

	rc4Base64,

	isBase64,

	base64encode,

	base64decode

} from 'npm-rc4';

```

## Examples

```js

console.log(

	rc4(

		'this text is going to be encrypted',

		'your keword'

	)

);

// => ]}*g ‚ÙÒo©“ÌܟNXàÝâ­rÀÀÛÎÿ‚¸

console.log(

	rc4Base64Encrypt(

		'this text is going to be encrypted and encoded with base64',

		'your keword'

	)

);

		'your keword'

	)

);

// => this text is decrypted and decoded with base64

console.log(

	rc4Base64(

		'this function understands if the string have to be decoded or encoded with base64',

		'your keword'

	)

);

// => XX0qG8KkdcKwwpTDjkPDknPDp8OUw5bDm8KVTArDp8OGwqPCoXPCk8OeYMOFwonDgwXDrsOHwq8Cw45hVMO6w5/DlcKmw7wNO27DsR7CpH9Lc8K2dMOOwqA4w4TCicO4T8KHAzNlw4RvOsOvwp/DgSlgw6swwr3CpC1Swq14

		'your keword'

	)

	

);

// => this function understands if the string have to be decoded or encoded with base64

console.log(

	isBase64('Y2lhbw==')

	

);

// => true

console.log(

	isBase64('this string is not base64 of course')

	

);

// => false

console.log(

	base64encode('this string will be encoded with base64')

	

);

// => dGhpcyBzdHJpbmcgd2lsbCBiZSBlbmNvZGVkIHdpdGggYmFzZTY0

console.log(

	base64decode('dGhpcyBzdHJpbmcgd2lsbCBiZSBkZWNvZGVkIHdpdGggYmFzZTY0')

	

);

// => this string will be decoded with base64

```

That's it :)
