Readme
A static class that simplifies encryption/decryption using the AES 256 GCM algorithm.
Just use a one-liner to encrypt or decrypt - the IV and tag are handled automatically.
const Aes = require('aes-256-gcm');
// Must be 32 bytes.
const SHARED_SECRET = '12345678901234567890123456789012';
// Encrypt:
let { ciphertext, iv, tag } = Aes.encrypt('hi', SHARED_SECRET);
// ciphertext: 'VOE='
// iv: '0K6oPWsBAHLXYtLu5VAvsQ=='
// tag: 'hCae3Lt5sAK3oNAnUh5emA=='
// Decrypt:
let cleartext = Aes.decrypt(ciphertext, iv, tag, SHARED_SECRET;
// `cleartext` contains:
// 'hi'
Encrypts the text
using the 256-bit shared key (secret
) and returns an object
containing three base64-encoded strings:
{
"ciphertext": "(string)",
"iv": "(string)",
"tag": "(string)"
}
All of those strings must be passed to the end user to successfully decrypt the text.
Decrypts the ciphertext
using the iv
and authentication tag tag
received
from the encryption function, and using the 256-bit shared key (secret
).
Returns the decoded string.
