| 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.
