Krypt: Simple, Secure, Symmetric Encryption

Krypt uses encryption best practices to produce very secure, portable JSON objects using a simple shared key.

Install

npm install -g krypt

CLI Usage

Encryption

krypt --encrypt ./path/to/file.json --secret someSecretValue --out ./path/to/new/encrypted.out

Decryption

krypt --decrypt ./path/to/new/encrypted.out --secret someSecretValue --out ./path/to/file.json

Module Usage

Encryption

var krypt = require('krypt');

var encryptedSync = krypt.encrypt('Input Value', 'someSecretValue');

krypt.encrypt(encrypted, 'someSecretValue', function (err, encryptedAsync) {
  // async encrypt
});

Decryption

var krypt = require('krypt');

var plainTextSync = krypt.decrypt(encrypted, 'someSecretValue');

krypt.decrypt(encrypted, 'someSecretValue', function (err, plainTextAsync) {
  // async decrypt
});

Algorithms

Krypt tries to incorporate current encryption best practices into a simple to use module. As such, Krypt uses the following:

• AES 256
• CBC
• Key Stretching w/ PBKDF2 @ 128,000 iterations (default)
• Random IV / encrypted value
• Random salt / encrypted value
• sha512 digest
