IDicomSecurityCiphers Interface

Summary

Allows implementors to specify a list of supported DICOM TLS Cipher Suites in an add-in.

Syntax

C++

public interface IDicomSecurityCiphers

Public Interface IDicomSecurityCiphers

public: 
   interface class IDicomSecurityCiphers abstract

Remarks

A DICOM add-in implements this interface to specify a list of DicomTlsCipherSuiteType values that are to be supported when using secured DICOM TLS communication.

In the PACS Framework, the Leadtools.Medical.Security.AddIn.dll implements this interface. For detailed example usage, see the source code for the Leadtools.Medical.Security.AddIn.dll.

Example

This example shows a basic PACS Framework add-in that implements the IDicomSecurity and IDicomSecurityCiphers interfaces.
