2.4.3. Checksum Validation

Checksum validation is used to ensure a downloaded file has not been corrupted. Checksum validation employs algorithms that compute a fixed-size datum (or checksum) from an arbitrary block of digital data. If two parties compute a checksum of a particular file using the same algorithm, the results will be identical. Therefore, when computing the checksum of a downloaded file using the same algorithm as the supplier, if the checksums match, the integrity of the file is confirmed. If there is a discrepancy, the file has been corrupted in the download process.

2.4.4. Verify the Downloaded File

Procedure 2.3. Verify the Downloaded File

  1. To verify that a file downloaded from the Red Hat Customer Portal is error-free, access the portal site and go to that package's Software Details page. The Software Details page displays the MD5 and SHA256 "checksum" values. Use the checksum values to check the integrity of the file.
  2. Open a terminal window and run either the md5sum or sha256sum command, with the downloaded file as an argument. The program displays the checksum value for the file as the output for the command.
  3. Compare the checksum value returned by the command to the corresponding value displayed on the Software Details page for the file.

    Note

    Microsoft Windows does not come equipped with a checksum tool. Windows operating system users have to download a third-party product instead.
Result

If the two checksum values are identical then the file has not been altered or corrupted and is, therefore, safe to use.

If the two checksum values are not identical, then download the file again. A difference between the checksum values means that the file has either been corrupted during download or has been modified since it was uploaded to the server. If, after several downloads, the checksum will still not successfully validate, contact Red Hat Support for assistance.
