Public Shared Function Create (algorithm As String) As ECDiffieHellman

Parameters

Remarks

If you develop your own implementation of an ECDiffieHellman object, you can use the Create(String) method overload to create a custom algorithm string that specifies your implementation.

The algorithm parameter specifies the name of an implementation of the ECDH algorithm. The following strings all refer to the same implementation, which is the only implementation currently supported in the .NET Framework:

"ECDH"

"ECDiffieHellman"

"ECDiffieHellmanCng"

"System.Security.Cryptography.ECDiffieHellmanCng"

You can also provide the name of a custom ECDH implementation for the algorithm parameter. If you do that, the CryptoConfig object will use it to determine whether an ECDH object can be created.
