JSON Object Crypto

A utility for encrypting and decrypting JSON objects with selective field encryption. This package allows you to encrypt specific fields in your JSON objects while keeping others in plain text.

Features

• Encrypt and decrypt JSON objects
• Selective field encryption
• Support for nested objects and arrays
• Uses AES-256-CBC encryption by default
• Configurable encryption algorithm and encoding

Installation

npm install json-object-crypto

Usage

const crypto = require('json-object-crypto');

// Example object
const data = {
  name: "John Doe",
  email: "[e-mail]",
  password: "secret123",
  address: {
    street: "123 Main St",
    city: "New York"
  }
};

// Encrypt specific fields
const encrypted = crypto.encrypt(data, "your-secret-key");

// Decrypt the encrypted object
const decrypted = crypto.decrypt(encrypted, "your-secret-key");
