Method	Description
GetCertificateEnumerator	Gets a pointer to an IOpcCertificateEnumerator interface, which enumerates the package certificates that are attached to the signature.
GetCustomObjectEnumerator	Gets a pointer to an IOpcSignatureCustomObjectEnumerator interface, which enumerates the custom objects of the signature.
GetCustomReferenceEnumerator	Gets a pointer to an IOpcSignatureReferenceEnumerator interface, which enumerates the custom references of the signature.
GetPolicy	Gets the XPS_SIGN_POLICY value that represents the signing policy used when the signature is created.
GetSignatureId	Gets the value of the Id attribute of the Signature element.
GetSignaturePartName	Gets the part name of the signature part.
GetSignatureValue	Gets the encrypted hash value of the signature.
GetSignatureXml	Gets the XML markup of the digital signature.
GetSigningTime	Gets the date and time of signature creation.
GetSigningTimeFormat	Gets the format of the signing time.
SetSignatureXml	Sets the XML markup of the digital signature.
Verify	Verifies the signature against a specified X.509 certificate.

Remarks

This interface is linked to the signature manager from which it was instantiated and it cannot exist independently.

An IXpsSignature interface may represent a signature that is not XPS compliant. For example, it could represent a signature that includes only custom parts, which is not allowed by the XML Paper Specification.

Requirements

Minimum supported client	Windows 7 [desktop apps only]
Minimum supported server	Windows Server 2008 R2 [desktop apps only]
