| object | Message (MSMQMessage) object that defines the message. |
Security certificate (internal or external).
The sending application can specify an external certificate obtained from a certificate authority, or use the internal certificate provided by MSMQ.
When using external certificates, the receiving application can use all the information in the certificate to verify who sent the message. When using an internal certificate, this property is not useful to the receiving application.
There are two ways to specify the security information provided by a certificate. If the sending application is only going to use a certificate once, it should provide the complete certificate using SenderCertificate. If the sending application is going to use the same certificate over and over, it should call AttachCurrentSecurityContext. AttachCurrentSecurityContext retrieves and caches the needed information using a single call, then automatically passes the information along with the message when it is sent.
