$ yarn add @47ng/cloak
# or
$ npm i @47ng/cloak
The package comes with a CLI tool you can use to generate and manage keys, as well as encrypting and decrypting data in the terminal:
$ cloak --help
Usage: cloak [options] [command]
Options:
-h, --help output usage information
Commands:
generate Generate an AES-GCM key
encrypt [options] [key] Encrypt stdin
decrypt Decrypt stdin
revoke <keyFingerprint> Remove a key from the environment keychain
keychain [options] [full] List the contents of the environment keychain
# Start by generating an empty keychain and master key:
$ cloak generate
Key: k1.aesgcm256.DL2G9PQeZ9r65J59pph6dy9Sk4fBLEZ3CTQZsandgYE=
Fingerprint: 6f28c026
Generated new empty keychain:
export CLOAK_MASTER_KEY=k1.aesgcm256.DL2G9PQeZ9r65J59pph6dy9Sk4fBLEZ3CTQZsandgYE=
export CLOAK_KEYCHAIN=v1.aesgcm256.6f28c026.yhCUkzv5gOyHJ2M_.jrGSf2_MPVofk-kSDgnYzvEy
# Copy/paste the exports into your terminal
# (the CLI does not mutate your environment directly)
$ export CLOAK_MASTER_KEY=k1.aesgcm256.DL2G9PQeZ9r65J59pph6dy9Sk4fBLEZ3CTQZsandgYE=
$ export CLOAK_KEYCHAIN=v1.aesgcm256.6f28c026.yhCUkzv5gOyHJ2M_.jrGSf2_MPVofk-kSDgnYzvEy
# Generate a key to use for encryption
$ cloak generate
Key: k1.aesgcm256.pHLFYdaqXut62LoFbt8KV80x_YNyZPmY0kQaPhJ0Ehc=
Fingerprint: cd38bcc4
Updated keychain:
export CLOAK_MASTER_KEY=k1.aesgcm256.DL2G9PQeZ9r65J59pph6dy9Sk4fBLEZ3CTQZsandgYE=
export CLOAK_KEYCHAIN=v1.aesgcm256.6f28c026.jr9fqMA_RfNhIjHz.lo4IfIYfZ0zxrdSns_ibWq6YX1D5AnzN-fhUF0CKVx5dRVIo0x-Atumr9WZqpHOeEIWT5bEGFKHhxGkFdwk2vg5TZQNk5Rj_jo3hnfSLaFAYncG59dB jUkz1JE0Plq2d-GR1AbDs6P18VzOG_JrU
To use this new key as default for encryption:
export CLOAK_CURRENT_KEY=cd38bcc4
# Encrypt sdtin
$ echo 'Hello, World !' | cloak encrypt
v1.aesgcm256.cd38bcc4.yxAp2iONy7zYOhbs.X2zmGpmGw9a7tiSnyukEW8Ac-2IIcIENW5uHxtHYyA==
# Decrypt stdin
$ echo 'v1.aesgcm256.cd38bcc4.yxAp2iONy7zYOhbs.X2zmGpmGw9a7tiSnyukEW8Ac-2IIcIENW5uHxtHYyA==' | cloak decrypt
Hello, World !
// Works in the browser or in Node.js
import { generateKey, encryptString, decryptString } from '@47ng/cloak'
const demo = async () => {
const key = generateKey()
const cipher = await encryptString('Hello, World', key)
const decipher = await decryptString(cipher, key)
}
