Package Exports

@outofsync/aescrypt-helper

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@outofsync/aescrypt-helper) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

aescrypt-helper

aescrypt-helper is a pure Node.js set of simple tools to deal with the AES-256-CBC encryption and decryption of data with arbitrary lengths.

Installation

npm install @outofsync/aescrypt-helper

Usage

const AESCryptHelper = require('@outofsync/aescrypt-helper');

const secret = '41e8c08ff31f97547ac11cc47c29f8ce5cb187a70ef09226c0f025c25c55b5b3';
const iv = '3816d1474cf82f3182b83c390d3e8eb5';
const creds = { secret: null, iv: null };

creds.secret = Buffer.from(secret, 'hex');
creds.iv = Buffer.from(iv, 'hex');
const aescyptHelper = new AESCryptHelper(creds.secret, creds.iv);

console.log(aescryptHelper.decryptiv(aescryptHelper.encryptiv('Test Message')));

API Reference

AESCryptHelper constructor(secret, iv[, separator]) ⟾ instanceof AESCryptHelper

Create an instance of AESCryptHelper using the secret, and iv (initialization vector). A separator may also be specified to indicate how blocks are separated; however, this is unnecessary and only included for backwards compatibility. By default, no separator is used.

Note: The iv should exactly 16 bytes in length and the secret should be exactly 32 bytes in length.

AESCryptHelper.encryptiv(data [, secret] [, iv]) ⟾ Buffer

Encrypt the data Buffer with the configured secret or the optionally passed secret and the configured iv or the optionally passed iv. Returns the encrypted data in a Buffer.

AESCryptHelper.decryptiv(encryptedData [, secret] [, iv]) ⟾ Buffer

Decrypts the encryptedData Buffer with the configured secret or the optionally passed secret and the configured iv or the optionally passed iv. Returns the decrypted data in a Buffer.
