Caution

Cryptographic factory methods accepting an algorithm name are obsolete. Use the parameterless Create factory method on the algorithm type instead.

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

public:
 static System::Security::Cryptography::ECDsa ^ Create(System::String ^ algorithm);

public static System.Security.Cryptography.ECDsa? Create (string algorithm);

[<System.Obsolete("Cryptographic factory methods accepting an algorithm name are obsolete. Use the parameterless Create factory method on the algorithm type instead.", DiagnosticId="SYSLIB0045", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
static member Create : string -> System.Security.Cryptography.ECDsa

Public Shared Function Create (algorithm As String) As ECDsa

Parameters

algorithm

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.

Returns

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.

Attributes

ObsoleteAttribute

Exceptions

ArgumentNullException

The algorithm parameter is null.

Remarks

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.
