ECDsa::Create Method (String^)


Creates a new instance of the specified implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA).

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

static ECDsa^ Create(
	String^ algorithm


Type: System::String^

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

- "ECDsa"

- "ECDsaCng"

- "System.Security.Cryptography.ECDsaCng"

You can also provide the name of a custom ECDSA implementation.

Return Value

Type: System.Security.Cryptography::ECDsa^

A new instance of the specified implementation of this class. If the specified algorithm name does not map to an ECDSA implementation, this method returns null.

Exception Condition

The algorithm parameter is null.

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

If you specify a custom value for the algorithm parameter, the CryptoConfig object will use it to determine whether an ECDSA object can be created.
