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
- Upload the DIS SDK software package sdk-dis-x.x.x1.2.3.zip to any directory on the Linux system by using WinSCP.
In sdk-dis-x.x.x.zip, x.x.x indicates the version number of the DIS SDK software package.
- 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 8be2c937e8d78b1a9b99777cee4e7131f8bf231de3f839cf214e7c5b5ba3c088 cloud-sdk-dis-x.x.x.zip
- 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.
