crypto-aes-gcm

crypto-aes-gcm

Uses the SubtleCrypto interface of the Web Cryptography API to encrypt and decrypt text using AES-GCM (AES Galois counter mode).

This module uses the native (web)crypto API in node.js and the browser.

npm install crypto-aes-gcm

import { aesGcmEncrypt, aesGcmDecrypt } from 'crypto-aes-gcm';

// encryption
const ciphertext = await aesGcmEncrypt('my secret text', 'pw');
aesGcmEncrypt('my secret text', 'pw').then(function(ciphertext) { console.log(ciphertext); });

// decryption
const plaintext = await aesGcmDecrypt(ciphertext, 'pw');
aesGcmDecrypt(ciphertext, 'pw').then(function(plaintext) { console.log(plaintext); });

Origin story

The code was originally written by Chris Veness at this gist.

Then, it was published as a package with node.js compatability out of the box.
