arc4

RC4 stream cipher. You can select from ['arc4', 'rc4a', 'vmpc', 'rc4+'] algorithm, and encode/decode with different encodings for *String only.

My original python code

Installation

Install through NPM

npm install arc4

or

git clone git://github.com/hex7c0/arc4.git

API

inside nodejs project

var rc4 = require('arc4');

var cipher = rc4('arc4', 'secret_key');
var d = cipher.encodeString('ciao');
var e = cipher.decodeString(d);

Methods

change your key (warning) and reload gKsa

cipher.change('foo');

encode string data

cipher.encodeString('string','utf8','base64);

encode array data

cipher.encodeArray([49,50,51]);

encode buffer data

cipher.encodeBuffer(new Buffer('ciao'));

encode string or byte or buffer (switch type)

cipher.encode(your_data);

for decoding, change "encode*" to "decode*"

cipher.decode(your_data);

rc4(algorithm,password,[lodash])

algorithm

• algorithm - String | Array | Buffer Choose between ['arc4', 'rc4a', 'vmpc', 'rc4+'] (default "throw Error")

password

• password - String Your key (default "throw Error")

[lodash]

• lodash - Boolean Use lodash library (check benchmark test for right decision) (default "disabled")
