A text encryption library that has two functions currently:

1. Easy encryption (makes letter "a" to letter "f".)
2. Encryption with a password(AES) (Requires node.js version 15.0.0 and up.)

Installation

npm install ezcryption

Usage

Easy encryption

import Spoiler from "ezcryption/dist/spoiler";

Spoiler.encrypt("This is a secret message"); // Ymnx%25nx%25f%25xjhwjy%25rjxxflj
Spoiler.decrypt("Ymnx%25nx%25f%25xjhwjy%25rjxxflj"); // This is a secret message

Encryption with a password(AES)

Returns a promise.

import Aes from "ezcryption/dist/aes";

async function myFunction() {
  const encrypted = await Aes.encrypt("This is a secret message", "password");
  // 163e231e179e74e123e207e37e34e112e154e33e98e82e216e36e56e211e181e173e232e238e10e81e134e207e99e68e193e98e215e248e166

  const decrypted = Aes.decrypt(
    "163e231e179e74e123e207e37e34e112e154e33e98e82e216e36e56e211e181e173e232e238e10e81e134e207e99e68e193e98e215e248e166",
    "password"
  ); // This is a secret message
}

Optional

These options are not required but for more flexibility.

Encryption with a password(AES) options:

Add an object as a third parameter {options:{iv: customIv, salt: customSalt}}

• iv: Initialization vector for Aes. An array that contains 16 integer between 0 to 255 value range
• salt: A string for PBKDF2(key derivation function)

Example:

import Aes from "ezcryption/dist/aes";

const customIv = new Uint8Array([
  4, 214, 15, 14, 139, 254, 2, 1, 28, 19, 204, 14, 15, 0, 5, 6,
]);
const customSalt = "custom salt";

async function myFunction() {
  const encrypted = await Aes.encrypt("This is a secret message", "password", {
    options: { iv: customIv, salt: customSalt },
  }); // 78e173e11e207e148e208e76e35e47e68e75e19e93e55e76e57e111e136e150e77e44e89e69e104e110e131e196e154e32e22e39e220

  const decrypted = await Aes.decrypt(
    "78e173e11e207e148e208e76e35e47e68e75e19e93e55e76e57e111e136e150e77e44e89e69e104e110e131e196e154e32e22e39e220",
    "password",
    {
      options: { iv: customIv, salt: customSalt },
    }
  ); // This is a secret message
}
