Ciphering

The typical use case for this high speed Node.js module is to convert data in common text to encrypted string.

Encryption and decryption of the data is done with the help of military grade encryption (AES-256) crypto.

The data is encrypted with three levels of encryption excluding the one which uses the master key.

Most modern macOS, Windows and Linux systems running Node.js >= 12.13.0 do not require any additional install or runtime dependencies.

Examples

npm install ciphering

const { decrypt, encrypt } = require('ciphering');

// or

import { decrypt, encrypt } from 'ciphering';

General

1. Create a password (key),
2. Must be protected and saved in .env file when deployed in production.

const key: string = process.env.KEY as string;

Encrypting Data

const data: string = "my-personal-data"; // data which to be encrypted
const encryption = encrypt.encryptData({ data, key });

/**
 * output:
 *  {
 *      token: 'd811948ba5dd95584ddf847afc8601c3:5a0229c6cecc095a92b5a3ee1a793240',
 *      vector: <Buffer d8 11 94 8b a5 dd 95 58 4d df 84 7a fc 86 01 c3>
 *  }
 */

Decrypting Data

// To decrypt data we'll need the encrypted_data token.
const decryption = decrypt.decryptData({ token: encryption.token, key });

decryption
    .then(console.log) // "my-personal-data"
    .catch(console.error); // error: unknown
