npm-rc4 v1.0.13

npm-rc4

A list of useful rc4 and base64 functions for Node.js 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.

Installing

Using npm:

$ npm install npm-rc4

Node.js

const {
	rc4,
	rc4Base64Encrypt,
	rc4Base64Decrypt,
	rc4Base64,
	isBase64,
	base64encode, 
	base64decode
} = require('npm-rc4');

ES6

import {
	rc4,
	rc4Base64Encrypt,
	rc4Base64Decrypt,
	rc4Base64,
	isBase64,
	base64encode,
	base64decode
} from 'npm-rc4';

Examples

console.log(

	rc4(
		'this text is going to be encrypted',
		'your keword'
	)

);
// => ]}*g ‚ÙÒo©“ÌܟNXàÝâ­rÀÀÛÎÿ‚¸

	)
	
);
// => 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 :)
