a simple encrypt and decrypt module for node.js
npm install cryptrcryptr is a simple aes-256-gcm encrypt and decrypt module for node.js
It is for doing simple encryption of values UTF-8 strings that need to be decrypted at a later time.
If you require anything more than that you probably want to use something more advanced or crypto directly.
The Cryptr constructor takes 1 required argument, and an optional options object.
Cryptr(secret[, options])
- secret:
- options:
- encoding:
- pbkdf2Iterations:
- saltLength:
The salt and iv are randomly generated and prepended to the result.
DO NOT USE THIS MODULE FOR ENCRYPTING PASSWORDS!
Passwords should be a one way hash. Use bcrypt for that.
npm install cryptr
``javascript
const Cryptr = require('cryptr');
const cryptr = new Cryptr('myTotallySecretKey');
const encryptedString = cryptr.encrypt('bacon');
const decryptedString = cryptr.decrypt(encryptedString);
console.log(encryptedString); // 2a3260f5ac4754b8ee3021ad413ddbc11f04138d01fe0c5889a0dd7b4a97e342a4f43bb43f3c83033626a76f7ace2479705ec7579e4c151f2e2196455be09b29bfc9055f82cdc92a1fe735825af1f75cfb9c94ad765c06a8abe9668fca5c42d45a7ec233f0
console.log(decryptedString); // bacon
`
#### With Options
`javascript
const Cryptr = require('cryptr');
const cryptr = new Cryptr('myTotallySecretKey', { encoding: 'base64', pbkdf2Iterations: 10000, saltLength: 10 });
const encryptedString = cryptr.encrypt('bacon');
const decryptedString = cryptr.decrypt(encryptedString);
console.log(encryptedString); // CPbKO/FFLQ8lVKxV+jYJcLcpTU0ZvW3D+JVfUecmJmLYY10UxYEa/wf8PWDQqhw=
console.log(decryptedString); // bacon
