WebMay 9, 2013 · For ephemeral Diffie-Hellman (DHE) cipher suites, the RSA private key is only used for signing the DH parameters (and not for encryption). These parameters are used in a DH key exchange, resulting in a shared secret (effectively the pre-master secret which is of course not visible on the wire). WebRSA is two algorithms, one for asymmetric encryption, and one for digital signatures. These are two distinct beast; although they share the same core mathematical operation and format for keys, they do different things in different ways. ...

WebSummary: when talking about DH, a "big" size like 1024 or 3072 normally means "the size of p", while a "small" size like 160 or 256 normally means "the size of q" or "the size of t".There is no standard for "the size", and indeed the standard does not define a unique one-size-fits-all size. In your Wikipedia quote, the "3072 bits" is the size of p (the modulus). WebJan 20, 2024 · 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.
