How Do I Check Software Package Integrity?

This section describes how to verify integrity of the DIS SDK software package on a Linux system by using a verification file.

Prerequisites

  • The PuTTY tool is available.

  • The WinSCP tool is available.

Procedure

  1. Upload the DIS SDK software package sdk-dis-x.x.x1.2.3.zip to any directory on the Linux system by using WinSCP.

    Note

    In sdk-dis-x.x.x.zip, x.x.x indicates the version number of the DIS SDK software package.

  2. Log in to the Linux system by using PuTTY. In the directory in which sdk-dis-x.x.x1.2.3.zip is stored, run the following command to obtain the verification code of the DIS SDK software package

    sha256sum sdk-dis-x.x.x.zip

    Example verification code:

    # sha256sum dis-sdk-x.x.x.zip

  3. Open the DIS SDK verification file sdk-dis-x.x.x1.2.3.zip.sha256sum and compare it with the verification code obtained in Step 2.

    • If they are consistent, the DIS-SDK compression package has not been tampered with.

    • If they are inconsistent, the DIS SDK software package is tampered with and you need to obtain it again.
