Public Function GetMacTransferSyntax( _
ByVal signatureItem As DicomElement _
) As String
The Digital Signatures Sequence Item that corresponds to the Digital Signature. This cannot be null.
The MAC Calculation Transfer Syntax UID (0400,0010) used in the creation of the specified Digital Signature. The return value can be a null reference (Nothing in VB).
The Digital Signatures Sequence Item of a Digital Signature should reference an item under the MAC Parameters Sequence associated with the Digital Signatures Sequence. The MAC Calculation Transfer Syntax UID (0400,0010) under the referenced MAC Parameters Sequence Item specifies the Transfer Syntax used in the calculation of the Message Authentication Code (MAC). The encrypted MAC is the digital signature itself. Call this method to obtain the value of this Data Element. If the Data Set was properly encoded, the return value will be a Transfer Syntax that Explicitly includes the Value Representation (VR) and uses Little Endian encoding.
The following methods can also be used to get information about the Digital Signature:
For an example, refer to VerifySignature.
