X509AsymmetricSecurityKey.GetSignatureDeformatter(String) Method

Definition

Namespace:

System.IdentityModel.Tokens

Assembly:

System.IdentityModel.dll

Gets the de-formatter algorithm for the digital signature.

public:
 override System::Security::Cryptography::AsymmetricSignatureDeformatter ^ GetSignatureDeformatter(System::String ^ algorithm);

public override System.Security.Cryptography.AsymmetricSignatureDeformatter GetSignatureDeformatter (string algorithm);

override this.GetSignatureDeformatter : string -> System.Security.Cryptography.AsymmetricSignatureDeformatter

Public Overrides Function GetSignatureDeformatter (algorithm As String) As AsymmetricSignatureDeformatter

Parameters

algorithm

String

The de-formatter algorithm for the digital signature to get an instance of.

Returns

AsymmetricSignatureDeformatter

An AsymmetricSignatureDeformatter that represents the de-formatter algorithm for the digital signature.

Exceptions

NotSupportedException

algorithm is XmlDsigDSAUrl and the public key for the X.509 certificate specified in the constructor is not of type DSA.

-or-

algorithm is XmlDsigRSASHA1Url or RsaSha256Signature and the public key for the X.509 certificate specified in the constructor is not of type RSA.

-or-

algorithm is not supported. The supported algorithms are XmlDsigDSAUrl,

XmlDsigRSASHA1Url, and RsaSha256Signature.

Remarks

Use the XmlDsigDSAUrl, XmlDsigRSASHA1Url or RsaSha256Signature fields to specify the algorithm parameter.
