Gets or sets the digital signature that Message Queuing uses to authenticate the message.
Assembly: System.Messaging (in System.Messaging.dll)
Message Queuing uses the digital signature when authenticating messages that were sent by Message Queuing version 1.0. In most cases, Message Queuing generates and sets the property when the sending application requests authentication. The receiving application uses this property to retrieve the digital signature attached to the message.
You can only use the property when running Message Queuing version 2.0. The sending application must specify Message Queuing version 1.0 signatures when requesting authentication. If the sending application sends a Message Queuing version 2.0 signature, this property contains a buffer of four bytes, each containing zero.
The property, together with the SenderCertificate property, is also used by connector applications when a message is sent. In this scenario, the connector application—rather than Message Queuing—generates the digital signature, which it bases on the certificate of the user sending the message.
The property has a maximum array size of 256.
