警告

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

建立指定的橢圓曲線數位簽章演算法(ECDSA)實例。

 static System::Security::Cryptography::ECDsa ^ Create(System::String ^ algorithm);
[System.Diagnostics.CodeAnalysis.RequiresUnreferencedCode("The default algorithm implementations might be removed, use strong type references like 'RSA.Create()' instead.")]

static member Create : string -> System.Security.Cryptography.ECDsa
Public Shared Function Create (algorithm As String) As ECDsa

參數

algorithm
String

ECDSA 實作名稱。 以下字串皆指同一實作,這是目前 .NET 框架中唯一支援的實作:

  • 「ECDsa」

  • 「ECDsaCng」

  • 「系統安全.密碼學.ECDsaCng」

你也可以提供自訂的 ECDSA 實作名稱。

傳回

這是該類別指定實作的新實例。 若指定的演算法名稱未映射到 ECDSA 實作,此方法會回傳 null。

屬性

例外狀況

參數 algorithm 為 null。

備註

如果你自己開發物件實作 ECDsa ,可以用 Create(String) 方法超載來建立 algorithm 自訂字串來指定你的實作。

如果你為參數指定自訂值 algorithm , CryptoConfig 物件會用它來判斷是否能建立 ECDSA 物件。
