Simple AES-GCM encryption and decryption utilities powered by the Web Crypto API.

Features ✨

• 🔒 Encrypt text using AES-GCM.
• 🔓 Decrypt encrypted payloads back into plaintext.
• ⚡ Uses the native Web Crypto API (no external dependencies).
• 🌐 Works in Deno, Node.js (18+), and modern browsers.
• 📦 Small, tree-shakeable, and ESM-first.

Installation 📦

• Deno:

  deno add jsr:@dep/aes

• Node.js (18+) or Browsers:

Usage 🎯

API 🧩

Encrypt text:

import { encrypt } from '@dep/aes';

const cipherText = await encrypt('MI4KP4050TD065782', 'dycxov-dYsxir-gykmi7');

console.log(cipherText);
// +vq7dCWJKmBKQN1Z50dzLyDjd5tpwCinAQKt/Mjfvj48g/EKjFZSQX6/2q1V

Decrypt text:

import { decrypt } from '@dep/aes';

const plainText = await decrypt(
  '+vq7dCWJKmBKQN1Z50dzLyDjd5tpwCinAQKt/Mjfvj48g/EKjFZSQX6/2q1V',
  'dycxov-dYsxir-gykmi7',
);

console.log(plainText);
// MI4KP4050TD065782

You can also use the namespace export:

import { aes } from '@dep/aes';

const encrypted = await aes.encrypt(
  'MI4KP4050TD065782',
  'dycxov-dYsxir-gykmi7',
);
const decrypted = await aes.decrypt(
  '+vq7dCWJKmBKQN1Z50dzLyDjd5tpwCinAQKt/Mjfvj48g/EKjFZSQX6/2q1V',
  'dycxov-dYsxir-gykmi7',
);
