Configure Checksumming

Checksumming is the process by which a quantity is calculated based on the contents of a message. The sender of the message calculates the checksum. The value of the checksum is included as part of the message packet. The recipient of the message re-computes the checksum of the message upon receipt. The two checksum values must match if the message is to be considered unaltered during transit.

To configure checksumming:

  1. In the navigator pane, expand Net8 Configuration > Local > Profile.

  2. From the list in the right pane, select Oracle Advanced Security.

  3. Click the Integrity tab.

  4. Enable client or server checksumming by clicking in either the Client or Server checkbox respectively.

  5. Specify how the client and the server will negotiate checksumming. You must select Checksum Levels for both the client and the server. The checksumming values are described below:

    Accepted
    Service will be active if the other side of the connection specifies either "required" or "requested", and there is a compatible algorithm available on the other side; it will otherwise be inactive.
    Rejected
    Service must not be active, and the connection will fail if the other side specifies "required".
    Requested
    Service will be active if the other side of the connection specifies either "accepted", "required", or "requested", and there is a compatible algorithm available on the other side; it will otherwise be inactive.
    Required
    Service must be active, and the connection will fail if the other side specifies "rejected", or if there is no compatible algorithm on the other side.

  6. Choose File > Save Network Configuration.
