WebFeb 4, 2014 · Even when ECDH is used for the key exchange, most SSH servers and clients will use DSA or RSA keys for the signatures. If you want a signature algorithm based on elliptic curves, then that's ECDSA or Ed25519; for some technical reasons due to the precise definition of the curve equation, that's ECDSA for P-256, Ed25519 for Curve25519. WebSep 24, 2011 · ECDH is not an encryption algorithm; it cannot encrypt some data you choose. It is a key agreement protocol, which results in a "shared secret": the data which both sender and receiver end up sharing is "secret" (only them know it) but they cannot control its contents.
