Parameters
- signatureItem
- The Digital Signatures Sequence Item that corresponds to the Digital Signature. This cannot be null.
Return Value
The number of Data Elements covered by the specified Digital Signature.Example
For an example, refer to Leadtools.Dicom.DicomDataSet.VerifySignature.
Remarks
The Digital Signatures Sequence Item of a Digital Signature should reference an item under the Message Authentication Code (MAC) Parameters Sequence associated with the Digital Signatures Sequence. The Data Elements Signed (0400,0020) under the referenced MAC Parameters Sequence Item specifies the signed Data Elements. Call this method to obtain the number of Data Elements specified by this Data Element.
Along with this method, call the Leadtools.Dicom.DicomDataSet.GetSignedElement method to enumerate the Data Elements covered by the Digital Signature.
The following methods can also be used to get information about the Digital Signature:
Leadtools.Dicom.DicomDataSet.GetSignatureUID
Leadtools.Dicom.DicomDataSet.GetSignatureDateTime
