IOpcDigitalSignature interface (msopc.h)
Represents a package digital signature.
Inheritance
The IOpcDigitalSignature interface inherits from the IUnknown interface. IOpcDigitalSignature also has these types of members:
Methods
The IOpcDigitalSignature interface has these methods.
| IOpcDigitalSignature::GetCanonicalizationMethod Gets the canonicalization method that was applied to the SignedInfo element of the serialized signature. |
| IOpcDigitalSignature::GetCertificateEnumerator Gets an enumerator of certificates that are used in the signature. |
| IOpcDigitalSignature::GetCustomObjectEnumerator Gets an enumerator of IOpcSignatureCustomObject interface pointers that represent application-specific Object elements in the signature markup. |
| IOpcDigitalSignature::GetCustomReferenceEnumerator Gets an enumerator of the IOpcSignatureReference interface pointers that represent references to application-specific XML elements that have been signed. |
| IOpcDigitalSignature::GetNamespaces Gets the prefix and namespace mapping of the Signature element of the signature markup. |
| IOpcDigitalSignature::GetPackageObjectReference Gets an IOpcSignatureReference interface pointer that represents the reference to the package-specific Object element that has been signed. |
| IOpcDigitalSignature::GetSignatureId Gets the value of the Id attribute from the Signature element of the signature markup. |
| IOpcDigitalSignature::GetSignatureMethod Gets the signature method used to calculate the value in the SignatureValue element of the signature markup. |
| IOpcDigitalSignature::GetSignaturePartName Gets the part name of the part that contains the signature markup. |
| IOpcDigitalSignature::GetSignaturePartReferenceEnumerator Gets an enumerator of IOpcSignaturePartReference interface pointers, which represent references to parts that have been signed. |
| IOpcDigitalSignature::GetSignatureRelationshipReferenceEnumerator Gets an enumerator of IOpcSignatureRelationshipReference interface pointers, which represent references to relationships that have been signed. |
| IOpcDigitalSignature::GetSignatureValue Gets the decoded value in the SignatureValue element of the signature markup. |
| IOpcDigitalSignature::GetSignatureXml Gets the signature markup. |
| IOpcDigitalSignature::GetSigningTime Gets a string that indicates the time at which the signature was generated. |
| IOpcDigitalSignature::GetTimeFormat Gets the format of the string returned by the GetSigningTime method. |
Remarks
To generate a signature and create an IOpcDigitalSignature interface pointer, call the IOpcDigitalSignatureManager::Sign method.
To access generated signature by using an IOpcDigitalSignature interface pointer, call the IOpcDigitalSignatureEnumerator::GetCurrent method.
When a signature is generated, this information is serialized in the XML markup of the signature (signature markup). The signature markup that results is stored in a signature part.
Thread Safety
Packaging objects are not thread-safe.
