WebJan 20, 2024 · To enable FS: Configure TLS 1.2 to use the Elliptic Curve Diffie-Hellman (EDCHE) key exchange algorithm (with DHE as a fallback), and avoid RSA key exchange completely if possible. Use TLS 1.3. TLS 1.3 provides forward secrecy for all TLS sessions via the the Ephemeral Diffie-Hellman (EDH or DHE) key exchange protocol. WebThe exact steps within a TLS handshake will vary depending upon the kind of key exchange algorithm used and the cipher suites supported by both sides. The RSA key exchange algorithm, while now considered not secure, was used in versions of TLS before 1.3. It goes roughly as follows: svetci ili sveci pravopis
