Assembly:  ReachFramework (in ReachFramework.dll)

public XpsDigitalSignature SignDigitally(
	X509Certificate certificate,
	bool embedCertificate,
	XpsDigSigPartAlteringRestrictions restrictions


Type: System.Security.Cryptography.X509Certificates.X509Certificate

The X.509 certificate to use in signing each part; or null to prompt the user to select an installed certificate.

Type: System.Boolean

true to store the certificate in the package; otherwise, false.

Type: System.Windows.Xps.Packaging.XpsDigSigPartAlteringRestrictions

An XpsDigitalSignature that contains information about the signature.

If certificate is null, a dialog box appears that enables the user to select an installed X.509 certificate, such as from a smart card reader.

The following example shows how to use the SignDigitally method.
