autokey

Autokey stream cipher.

Encode/decode with different encodings for *String only, from nodejs doc:

• 'ascii' - for 7 bit ASCII data only. This encoding method is very fast, and will strip the high bit if set.
• 'utf8' - Multibyte encoded Unicode characters. Many web pages and other document formats use UTF-8.
• 'utf16le' - 2 or 4 bytes, little endian encoded Unicode characters. Surrogate pairs (U+10000 to U+10FFFF) are supported.
• 'ucs2' - Alias of 'utf16le'.
• 'base64' - Base64 string encoding.
• 'binary' - A way of encoding raw binary data into strings by using only the first 8 bits of each character. This encoding method is deprecated and should be avoided in favor of Buffer objects where possible. This encoding will be removed in future versions of Node.
• 'hex' - Encode each byte as two hexadecimal characters.

My original python code

Installation

Install through NPM

npm install autokey

or

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

API

inside nodejs project

var autokey = require('autokey');

var cipher = autokey('secret_key');
var d = cipher.encodeString('ciao');
var e = cipher.decodeString(d);

Methods

change your key (warning)

cipher.change('foo');
cipher.change([30, 31]);
cipher.change(new Buffer('foo'));

encode a plaintext string, you can optionally choose input (defaults to 'utf8') and output (defaults to 'hex') encoding

cipher.encodeString(plaintext [, input_encoding] [, output_encoding]]);
cipher.encodeString('string', 'utf8', 'base64');

encode a plaintext array

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

encode a plaintext buffer data

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

select right function according with plaintext data type. Set input and output encoding only if data is a String

cipher.encode(your_data [, input_encoding] [, output_encoding]]);

decode a ciphertext string, you can optionally choose input (defaults to 'hex') and output (defaults to 'utf8') encoding

cipher.decodeString(ciphertext [, input_encoding [, output_encoding]]);
cipher.decodeString('string', 'utf8', 'base64');

decode a ciphertext array

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

decode a ciphertext buffer data

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

select right function according with ciphertext data type. Set input and output encoding only if data is a String

cipher.decode(your_data [, input_encoding [, output_encoding]]);

autokey(password , lodash)

password

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

lodash

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