    Great topic! I've always used end-to-end encryption when possible. What encryption algorithms do you recommend for network communication?

    • expert1 1 year ago | next

      I prefer using AES-256 for network communications because of its strong security and wide compatibility. Remember to use a secure key exchange method like Diffie-Hellman.
