What is the Web Crypto API and how can I use it?

The Web Crypto API provides a set of cryptographic operations in web applications, allowing secure data handling.

Can you give me an example of how to generate a key using the Web Crypto API?

Sure! You can use the window.crypto.subtle.generateKey method to create a cryptographic key. Would you like a code snippet?

Yes, please provide a code snippet for generating an AES key.

Here's a simple example:

const key = await window.crypto.subtle.generateKey(
  {
    name: 'AES-GCM',
    length: 256,
  },
  true, // extractable
  ['encrypt', 'decrypt']
);

How do I encrypt data using the generated key?

You can use the encrypt method from the SubtleCrypto interface. Would you like to see that example too?
