Public Function GetMacAlgorithm( _
ByVal signatureItem As DicomElement _
) As String
The Digital Signatures Sequence Item that corresponds to the Digital Signature. This cannot be null.
The MAC Algorithm (0400,0015) 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 Algorithm (0400,0015) under the referenced MAC Parameters Sequence Item specifies the algorithm used in generating the Message Authentication Code (MAC). The encrypted MAC is the digital signature itself. Call this method to obtain the value of this Data Element; Possible values are: "RIPEMD160", "SHA1", and "MD5". The following methods can also be used to get information about the Digital Signature:SaveCertificate
For an example, refer to VerifySignature.
