X509SigningCredentials Constructor (X509Certificate2, SecurityKeyIdentifier)

[Starting with the .NET Framework 4.5, Windows Identity Foundation (WIF) has been fully integrated into the .NET Framework. The version of WIF addressed by this topic, WIF 3.5, is deprecated and should only be used when developing against the .NET Framework 3.5 SP1 or the .NET Framework 4. For more information about WIF in the .NET Framework 4.5, also known as WIF 4.5, see the Windows Identity Foundation documentation in the .NET Framework 4.5 Development Guide.]

Initializes a new instance of the X509SigningCredentials class based on the specified X.509 certificate and security key identifier.

Namespace: Microsoft.IdentityModel.SecurityTokenService
Assembly: Microsoft.IdentityModel (in Microsoft.IdentityModel.dll)


Dim certificate As X509Certificate2
Dim ski As SecurityKeyIdentifier

Dim instance As New X509SigningCredentials(certificate, ski)


Public Sub New ( _
    certificate As X509Certificate2, _
    ski As SecurityKeyIdentifier _

    X509Certificate2 certificate, 
    SecurityKeyIdentifier ski
public function X509SigningCredentials (
    certificate : X509Certificate2, 
    ski : SecurityKeyIdentifier


  • ski
    A SecurityKeyIdentifier that represents the security key identifier to be used.


The key identifier clause types supported by Windows Communication Foundation for generating a security key identifier that references an X509SecurityToken are X509SubjectKeyIdentifierClause, X509ThumbprintKeyIdentifierClause, X509IssuerSerialKeyIdentifierClause, and X509RawDataKeyIdentifierClause. However, in order to enable custom scenarios, this constructor does not perform any validation on the clause types that were used to generate the security key identifier supplied in the ski parameter.
