multi-layers-encryption

Flexible encryption/decryption library with multiple configurable layers.
รองรับการเข้ารหัสหลายชั้น (Multi-layer) สามารถเลือก algorithm, secret key และ salt ได้เองในแต่ละชั้น

Features

• Choose multiple algorithms (AES, 3DES, etc.)
• Set secret key and salt per layer
• .encrypt(content) → encrypt through all layers
• .decrypt(content) → decrypt back through all layers

Installation

npm install multi-layers-encryption

for yarn:

yarn add multi-layers-encryption

Example:

JavaScript / TypeScript
import MultiLayerEncryption from "multi-layers-encryption";

const layers = [
  { algorithm: "aes-256-cbc", key: "layer1Key", salt: "layer1Salt" },
  { algorithm: "aes-192-cbc", key: "layer2Key", salt: "layer2Salt" }
];

const enc = new MultiLayerEncryption(layers);

const secret = "Hello Multi-Layer!";
const encrypted = enc.encrypt(secret);
const decrypted = enc.decrypt(encrypted);

console.log("Encrypted:", encrypted);
console.log("Decrypted:", decrypted);

Output

Encrypted: {"algorithm":"aes-192-cbc","iv":"...","data":"..."}
Decrypted: Hello Multi-Layer!

Algorithms Supported

Depends on Node.js crypto module (commonly supports):

• aes-256-cbc
• aes-192-cbc
• aes-128-cbc
• des-ede3-cbc
