cipherstream v0.1.1

cipher

cipher is a thin streaming layer for encryption/decryption.

Installation

npm install cipher

Usage

Require as cipher

var cipher = require("cipher");

CipherStream

CipherStream creates a Stream object which takes data in and encrypts it.

new CipherStream(password[, algorithm]) where algorithm defaults to AES192.

Example:

var cipher = require("cipher"),
    fs = require("fs");

fs.createReadStream("plain.txt").pipe(new cipher.CipherStream("secret")).pipe(fs.writeReadStream("secret.txt"));

DecipherStream

DecipherStream creates a Stream object which takes encrypted data in and decrypts it.

new DecipherStream(password[, algorithm]) where algorithm defaults to AES192.

Example:

var cipher = require("cipher"),
    fs = require("fs");

fs.createReadStream("secret.txt").pipe(new cipher.DecipherStream("secret")).pipe(fs.writeReadStream("plain.txt"));

HMAC

hmac is a simple wrapper function to create SHA-256 hmac values.

cipher.hmac(data, key) → String
