Assembly: System.Messaging (in system.messaging.dll)
Message authentication provides two services. It provides a way to ensure message integrity and a way to verify who sent the message. To request authentication, the sending application must set the authentication level of the message to be authenticated and attach a security certificate to the message.
To authenticate messages, the Message Queuing run-time DLL on the source computer uses a hashing algorithm when creating a digital signature for a message. The target Queue Manager then uses the same hashing algorithm to authenticate the message when it is received.
For more information about the authentication process, see the Message Queuing authentication topics in the MSDN Library.
