How can I implement a secure storage library in my application?

To implement a secure storage library, you should start by choosing a reliable library that supports encryption, like AES.

What are the key features I should look for in a secure storage library?

Look for features like data encryption, secure key management, access controls, and support for multiple platforms.

Can you give me an example of how to encrypt data using this library?

Sure! Here's a simple example using AES encryption:

const crypto = require('crypto');
const algorithm = 'aes-256-cbc';
const key = crypto.randomBytes(32);
const iv = crypto.randomBytes(16);

function encrypt(text) {
    let cipher = crypto.createCipheriv(algorithm, Buffer.from(key), iv);
    let encrypted = cipher.update(text);
    encrypted = Buffer.concat([encrypted, cipher.final()]);
    return { iv: iv.toString('hex'), encryptedData: encrypted.toString('hex') };
}

This function encrypts the input text.

How do I securely store the encryption keys?

You should use a secure key management system (KMS) or environment variables to store your encryption keys safely.
