(Read-only, introduced in MSMQ 2.0.) The PROPID_QM_ENCRYPTION_PK_BASE property indicates the public encryption key of the computer.

Property ID


Type Indicator




Property Value

Array of bytes that contains the public encryption key.


The PROPID_QM_ENCRYPTION_PK_BASE property is set by Message Queuing when Message Queuing is installed on the computer. PROPID_QM_ENCRYPTION_PK_BASE supersedes the PROPID_QM_ENCRYPTION_PK property.

To retrieve the public encryption key of the computer, include PROPID_QM_ENCRYPTION_PK_BASE in the MQQMPROPS structure, and then call MQGetMachineProperties and examine the returned property value.

When specifying PROPID_QM_ENCRYPTION_PK_BASE in the MQQMPROPS structure, set its type indicator to VT_NULL. Message Queuing automatically allocates memory for an array of bytes that receives the public encryption key during the function call. A pointer to this array is stored in the pElem member of the caub field of the MQPROPVARIANT structure. After you no longer need this buffer, you must free the memory allocated for it using MQFreeMemory.

Equivalent COM Property

There is no equivalent COM property or method for retrieving the public encryption key of a computer.

Example Code

The following code fragment shows how PROPID_QM_ENCRYPTION_PK_BASE is specified in the MQQMPROPS structure.

aQMPropId[i] = PROPID_QM_ENCRYPTION_PK_BASE; // Property identifier
aQMPropVar[i].vt = VT_NULL;                  // Type indicator
