WitrynaECDH is an elliptic curve varient of the standard Diffie-Hellamn key agreement protocol described in RFC 2631 and Public Key Cryptography Standard (PKCS) #3. The Generate Elliptic Curve Diffie-Hellman Key Pair (OPM, QC3GENECDK; ILE, Qc3GenECDHKeyPair) API generates a Diffie-Hellman (D-H) private/public key pair. Elliptic-curve Diffie–Hellman (ECDH) is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. This shared secret may be directly used as a key, or to derive another key. The key, or the derived key, can then be used to encrypt subsequent communications using a symmetric-key cipher. It is a variant of the Diffie–Hellman protocol using elliptic-curve cryptography.
