cryptr
cryptr 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:
<string>
- options:
<Object>
- encoding:
<string>
Defaults to 'hex' (see Node.js Buffer documentation for valid options) - pbkdf2Iterations:
<number>
Defaults to 100000 - saltLength:
<number>
Defaults to 64
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.
Install
npm install cryptr
Usage
const Cryptr = require('cryptr');
const cryptr = new Cryptr('myTotallySecretKey');
const encryptedString = cryptr.encrypt('bacon');
const decryptedString = cryptr.decrypt(encryptedString);
console.log(encryptedString);
console.log(decryptedString);
With Options
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);
console.log(decryptedString);
