Performs key derivation using the TLS (Transport Layer Security) 1.1 PRF (Pseudo-Random Function).

override cli::array <System::Byte> ^ DeriveKeyTls(System::Security::Cryptography::ECDiffieHellmanPublicKey ^ otherPartyPublicKey, cli::array <System::Byte> ^ prfLabel, cli::array <System::Byte> ^ prfSeed);public override byte[] DeriveKeyTls (System.Security.Cryptography.ECDiffieHellmanPublicKey otherPartyPublicKey, byte[] prfLabel, byte[] prfSeed);override this.DeriveKeyTls : System.Security.Cryptography.ECDiffieHellmanPublicKey * byte[] * byte[] -> byte[]Public Overrides Function DeriveKeyTls (otherPartyPublicKey As ECDiffieHellmanPublicKey, prfLabel As Byte(), prfSeed As Byte()) As Byte()Parameters
- otherPartyPublicKey
- ECDiffieHellmanPublicKey
The other party's public key.
- prfLabel
- Byte[]
The ASCII-encoded PRF label.
- prfSeed
- Byte[]
The 64-byte PRF seed.
Returns
The first 48 bytes from the TLS 1.1 PRF, using the shared secret as the key.
Exceptions
A derived class must override this method.
The curve used by otherPartyPublicKey has a different size than the curve from this key.
otherPartyPublicKey, prfLabel or prfSeed is null.
prfSeed is not exactly 64 bytes in length.
-or-
The curve used by otherPartyPublicKey is different than the curve from this key.
-or-
This instance represents only a public key.
