@mgraphic/cipher-token NPM

Link to the full API Documentation

A package tool to encrypt and decrypt secrets into storable string values without requiring a vault to store them. Tokens can ciphered and deciphered by a single key that can be generated by a string, buffer, file, or auto-generated (to be stored privately), or even a combination of these.

npm install @mgraphic/cipher-token

CLI Example

You can either use the prompt interaction to create a token, decipher a token, or generate a random string to be used for a key.

tokenize

npx @mgraphic/cipher-token tokenize --key=<secret key> [flags...] <plainText>

Code Examples

Key From String

const { getCipherToken, getDecipherToken } = require('@mgraphic/cipher-token');

//   Encrypt:
const cipherToken = getCipherToken();
cipherToken.keyFromString('secret_string_key');
const token = cipherToken.tokenize('Secret Text encrypted by a string key');
console.log('Token:', token);

// Decrypt:
const decipherToken = getDecipherToken();
decipherToken.keyFromString('secret_string_key');
const decrypted = decipherToken.untokenize(token);
console.log('Decrypted:', decrypted);

Key From File

const { getCipherToken, getDecipherToken } = require('@mgraphic/cipher-token');

//   Encrypt:
const cipherToken = getCipherToken();
await cipherToken.keyFromFile('package.json');
const token = cipherToken.tokenize('Secret Text encrypted by a file key');
console.log('Token', ': ', token);

//   Decrypt:
const decipherToken = getDecipherToken();
await decipherToken.keyFromFile('package.json');
const decrypted = decipherToken.untokenize(token);
console.log('Decrypted', ': ', decrypted);

Key From Buffer

const { getCipherToken, getDecipherToken } = require('@mgraphic/cipher-token');

//   Encrypt:
const cipherToken = getCipherToken();
cipherToken.keyFromBuffer(Buffer.from('buffer_key'));
const token = cipherToken.tokenize('Secret Text encrypted by a buffer key');
console.log('Token', ': ', token);

//   Decrypt:
const decipherToken = getDecipherToken();
decipherToken.keyFromBuffer(Buffer.from('buffer_key'));
const decrypted = decipherToken.untokenize(token);
console.log('Decrypted', ': ', decrypted);

Key From Buffer, File, and String

const { getCipherToken, getDecipherToken } = require('@mgraphic/cipher-token');

//   Encrypt:
const cipherToken = getCipherToken();
await cipherToken.keyFrom({
  buffer: Buffer.from('buffer_key'),
  text: 'secreat-key-string',
  file: 'package.json',
});
const token = cipherToken.tokenize('Secret Text encrypted by a combo key');
console.log('Token', ': ', token);

//   Decrypt:
const decipherToken = getDecipherToken();
await decipherToken.keyFrom({
  buffer: Buffer.from('buffer_key'),
  text: 'secreat-key-string',
  file: 'package.json',
});
const decrypted = decipherToken.untokenize(token);
console.log('Decrypted', ': ', decrypted);

Key From Random Generated String

const {
  getCipherToken,
  getDecipherToken,
  generateRandomString,
} = require('@mgraphic/cipher-token');

//   Encrypt:
const key = generateRandomString();
const cipherToken = getCipherToken();
cipherToken.keyFromString(key);
const token = cipherToken.tokenize(
  'Secret Text encrypted by a random bytes key'
);
console.log('Token', ': ', token);

//   Decrypt:
const decipherToken = getDecipherToken();
decipherToken.keyFromString(key);
const decrypted = decipherToken.untokenize(token);
console.log('Decrypted', ': ', decrypted);
