Arky

A library to encrypt and decrypt string in nodejs

It allows you to set your encryption key and decrypt with the the same encryption key.

Installation

npm install arky
// or
yarn add arky

Example

// You don't need this if you have a valid key.
const crypto = require("crypto");

const arky = require("arky");
// You can use whatever as the key
const key = crypto.randomBytes(32);
const testString = "This is the text to be encrypted";
const encrypted = arky.encrypt(testString, key);
console.log("Test String:", testString);
console.log("Hash Used:", encrypted.hash);
console.log("Hashed Key:", encrypted.key);

const decrypted = arky.decrypt(encrypted.hash, key);
console.log("Decrypted text:", decrypted);

// Output
// Test String: This is the text to be encrypted
// Hash Text: 8e12579f462e3bad1b4ab95d6789ccc291bcc17f0307b09f3b0be6d81a29a0e9f3ab9c001bb34d790121ea896b90563f
// Hashed Key: aZ75h8W5uTo798I+iV6vtERjMBLSl+ZkEbTlX0WO7OQ=
// Decrypted text: This is the text to be encrypted

APIs

encrypt() : {hash, key} | false

Encrypts a string

• text string The text to be encoded
• key string 32 bit string to used as a secret. Must be of 24 characters else it returns false
• algorithm string (optional) The encryption algorithm to use. Default to "aes-256-cbc".
• iv number (optional) The iv vector length to use. Default to 16.

The returned object contains a

• hash string the encrypted string
• key string the key used for hashing

decrypt() : {hash, key}

Decrypts a string

• hash string The encrypted string
• key string 32 bit string to used as a secret for encryption
• algorithm string (optional) The encryption algorithm to use. Default to "aes-256-cbc".
• iv number (optional) The iv vector length to use. Default to 16.

Returns a string matching the original text
