sec-obfuscate

sec-obfuscate
====================

_sec-obfuscate is a fork of the original sec-obfuscate-nodejs last updated in 2014. There have been deprecations since then, so this library addresses those._

sec-obfuscate is a library which obfuscates numbers (IDs etc...) using ciphers from OpenSSL.

Parameters

``js
var SecObfuscate = require("sec-obfuscate"),
secObfuscate = new SecObfuscate(key, iv, [cipher], [blockLength]);
`
cipher is a name of a encrption algorithm in OpenSSL notation. Default value is AES-256-CTR.
blockLength is a length of the output block. It have to be a multiple of 8. Default value is 32.

Ciphers

Currently only stream cipher (RC4) or AES with stream modes of operation are available:
* RC4
* AES-128-CTR
* AES-128-GCM
* AES-128-OFB
* AES-192-CTR
* AES-192-GCM
* AES-192-OFB
* AES-256-CTR
* AES-256-GCM
* AES-256-OFB

Usage

Code below presents a simple example of how the library can be used. More examples are available in _test_ directory.
`js
var SecObfuscate = require("sec-obfuscate"),
key = '0123456789abcdef0123456789abcdef',
iv = '0123456789abcdef'

secObfuscate = new SecObfuscate(key, iv),
encryptedValue = secObfuscate.encrypt(42),
decryptedValue = secObfuscate.decrypt(encryptedValue),
