WebECDH is a method for key exchange and ECDSA is used for digital signatures. ECDH and ECDSA using 256-bit prime modulus secure elliptic curves provide adequate protection for sensitive information. ECDH and ECDSA over 384-bit prime modulus secure elliptic curves are required to protect classified information of higher importance. Hash WebThe ECDH (Elliptic Curve Diffie–Hellman Key Exchange) is anonymous key agreement scheme, which allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. ECDH is very similar to the classical DHKE (Diffie–Hellman Key Exchange) algorithm, but it uses ECC point multiplication …
