AsymmetricAlgorithm.SignatureAlgorithm Property

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Source:

AsymmetricAlgorithm.cs

When implemented in a derived class, gets the name of the signature algorithm. Otherwise, always throws a NotImplementedException.

public:
 virtual property System::String ^ SignatureAlgorithm { System::String ^ get(); };

public virtual string? SignatureAlgorithm { get; }

member this.SignatureAlgorithm : string

Public Overridable ReadOnly Property SignatureAlgorithm As String

Property Value

String

The name of the signature algorithm.

Examples

The following code example demonstrates how to override the SignatureAlgorithm property to return the name of the signature algorithm. This code example is part of a larger example provided for the AsymmetricAlgorithm class.

    // This example uses the SHA1 algorithm.
    // Due to collision problems with SHA1, Microsoft recommends SHA256 or better.

public:
    property String^ SignatureAlgorithm
    {
        virtual String^ get() override
        {
            return "http://www.w3.org/2000/09/xmldsig#rsa-sha1";
        }
    }

// This example uses the SHA1 algorithm.
// Due to collision problems with SHA1, Microsoft recommends SHA256 or better.
public override string SignatureAlgorithm 
{
    get {return "http://www.w3.org/2000/09/xmldsig#rsa-sha1";}
}

' This example uses the SHA1 algorithm.
' Due to collision problems with SHA1, Microsoft recommends SHA256 or better.
Public Overrides ReadOnly Property SignatureAlgorithm() As String
    Get
        Return "http://www.w3.org/2000/09/xmldsig#rsa-sha1"
    End Get
End Property
