Definition
Important

When implemented in a derived class, performs a key derivation on the shared secret.
public:
virtual cli::array <System::Byte> ^ DeriveKeyMaterial(System::Security::Cryptography::ECDiffieHellmanPublicKey ^ otherPartyPublicKey);
public:
abstract cli::array <System::Byte> ^ DeriveKeyMaterial(System::Security::Cryptography::ECDiffieHellmanPublicKey ^ otherPartyPublicKey);
public virtual byte[] DeriveKeyMaterial (System.Security.Cryptography.ECDiffieHellmanPublicKey otherPartyPublicKey);
public abstract byte[] DeriveKeyMaterial (System.Security.Cryptography.ECDiffieHellmanPublicKey otherPartyPublicKey);
abstract member DeriveKeyMaterial : System.Security.Cryptography.ECDiffieHellmanPublicKey -> byte[]
override this.DeriveKeyMaterial : System.Security.Cryptography.ECDiffieHellmanPublicKey -> byte[]
abstract member DeriveKeyMaterial : System.Security.Cryptography.ECDiffieHellmanPublicKey -> byte[]
Public Overridable Function DeriveKeyMaterial (otherPartyPublicKey As ECDiffieHellmanPublicKey) As Byte()
Public MustOverride Function DeriveKeyMaterial (otherPartyPublicKey As ECDiffieHellmanPublicKey) As Byte()
Parameters
- otherPartyPublicKey
- ECDiffieHellmanPublicKey
The other party's public key.
Returns
The result of the key derivation function, using the shared secret as an input.
Exceptions
The curve used by otherPartyPublicKey
has a different size than the curve from this key.
otherPartyPublicKey
is null
.
The curve used by otherPartyPublicKey
is different than the curve from this key.
-or-
This instance represents only a public key.
Remarks
The default behavior of this method is equivalent to calling DeriveKeyFromHash specifying SHA-256 as the hash algorithm with no prepend or append values. Some implementations allow the behavior of this method to be changed, and callers are advised to call whichever method explicitly says it performs the key derivation they need.
