How do I use the Web Crypto API?

The Web Crypto API provides a set of functions to perform cryptographic operations in web applications. What specific functionality are you interested in?

I want to generate a secure random key.

You can use the window.crypto.getRandomValues() method to generate secure random values. Would you like an example?

Yes, please provide an example.

Here's a simple example:

const array = new Uint8Array(16);
window.crypto.getRandomValues(array);
console.log(array);

This will generate a random 16-byte key.

How can I use this key for encryption?

You can use the SubtleCrypto interface to encrypt data with the generated key. Would you like to see how?
