Description
When you access an SAP Adaptive Server Enterprise database in PowerBuilder through Open Client, Sec_Data_Origin is one of several parameters that support per-packet security for network-based security services. (For other per-packet security parameters, see the See Also section.)
Sec_Data_Origin controls whether your connection's security mechanism performs data origin stamping. When Sec_Data_Origin is set to 1, the security mechanism attaches a digital signature to each packet that verifies the packet's origin and contents.
When Sec_Data_Origin is set to 0 (the default), no data origin stamping is performed.
You must specify a value for Sec_Data_Origin before connecting to the database in PowerBuilder.
Using third-party security mechanisms
For information about the third-party security mechanisms and operating system platforms that has been tested with Open Client security services, see the Open Client documentation.

For details, see the section called “Requirements for using Open Client security services” in Connecting to Your Database.
Corresponding CT-Lib connection property
Specifying a value for Sec_Data_Origin sets the corresponding SAP Sybase CT-Lib connection property named CS_SEC_DATAORIGIN.
Examples
