Simple aes-256-gcm encryption and decryption module for NodeJS.
npm install @melkir/cryptoimport { randomBytes } from "node:crypto";
import { decrypt, encrypt } from "@melkir/crypto";
// The key must contain exactly 32 characters.
// The following instruction generates one randomly which you can then save in your environment variables.
const key = randomBytes(16).toString("hex");
const message = "Shh its a seekrit";
const encrypted = encrypt(message, key);
// You can now send your encrypted message to anyone without worrying about it being intercepted.
// The person who receives your message will then be able to decipher the content in the following way.
const decrypted = decrypt(encrypted, key);
