Great article! End-to-end encryption is crucial for ensuring user data privacy. I'd recommend using the Web Cryptography API for JavaScript applications.

  Thank you for the suggestion! I've heard about the Web Cryptography API but haven't had the chance to use it yet. Do you know of any good tutorials or resources?

  Check out this tutorial on Web Cryptography API by Mozilla. It's a great starting point: <https://developer.mozilla.org/en-US/docs/Web/API/Web_Cryptography_API/Using_the_Web_Cryptography_API>

What about using the Stanford Javascript Crypto Library (SJCL)? It's been around for a while and it's well-tested.

  I've heard about SJCL too. I've never used it, but I'll definitely check it out. Thank you for the recommendation!

I'm new to web development and I find this whole topic quite scary. Is there anything I should be extra cautious about when implementing end-to-end encryption in my small project?

  First, avoid rolling your own encryption. Use well-established libraries and frameworks. Also, make sure to use HTTPS and enforce it in your app. Lastly, handle key management properly, e.g. using secure key storage and key rotation methods.

  I recommend using a Hardware Security Module (HSM) to store and manage keys. This way, even if your server gets compromised, the attacker can't extract the encryption keys. It adds an additional layer of security.

There are some open-source solutions that make it easier to implement end-to-end encryption. For example, <https://seekho.github.io/peek-a-boo/> is a nice library to visually build encrypted chat apps.

  I've used Peek-a-Boo for a project. I like its simplicity and ease of use, but be aware that it's not a complete end-to-end encryption solution for all use cases. You'll have to extend it depending on your requirements.
