How Do I Download the RDA Installation Package and Verify Its Integrity?

You are advised to check the integrity of downloaded RDA installation packages, that is, check whether the packages are tampered with or packets are lost during download.

  1. On the RDA home page, click Installation Package.
  2. Click Download next to the link to download the desired RDA installation package to a local directory.

    Alternatively, click Copy and paste the address to the browser for download.

  3. Click Download next to SHA256 to download the file containing the hash value to a local directory.

    Alternatively, click Copy and paste the address to the browser for download.

  4. Open the CLI and run the following command to generate the hash value of the RDA installation package:

    • Windows
      certutil -hashfile C:\RDA-3.0.4.exe SHA256

      In the preceding command, "C:\RDA-3.0.4.exe" indicates the local path of the RDA installation package. Change it to the actual path.

    • Linux
      sha256sum RDA-3.0.4.tar.gz SHA256

      In the preceding command, "RDA-3.0.4.tar.gz" indicates the name of the RDA installation package. Change it to the name of the package you downloaded.

  5. Check whether the SHA256 hash value obtained in step 3 is consistent with that obtained in step 4.

    • If they are consistent, the installation package is complete.
    • If they are inconsistent, download the RDA installation package again and repeat step 3 and step 4 for verification.
