ECDiffieHellmanCng.DeriveKeyMaterial Method

 

Derives the key material that is generated from the secret agreement between two parties.

Namespace:   System.Security.Cryptography
Assembly:  System.Core (in System.Core.dll)

NameDescription
System_CAPS_pubmethodDeriveKeyMaterial(CngKey)

Derives the key material that is generated from the secret agreement between two parties, given a CngKey object that contains the second party's public key.

System_CAPS_pubmethodDeriveKeyMaterial(ECDiffieHellmanPublicKey)

Derives the key material that is generated from the secret agreement between two parties, given an ECDiffieHellmanPublicKey object that contains the second party's public key. (Overrides ECDiffieHellman.DeriveKeyMaterial(ECDiffieHellmanPublicKey).)

The Elliptic Curve Diffie-Hellman (ECDH) algorithm accepts the private key and the other party’s public key as input, and produces the secret agreement as output. The key derivation function (KDF) then takes the secret agreement and produces the key material as output.
