SHA256 checksums, which can be used to verify the integrity of any downloaded files, are available via download.delphix.com. Each download link should list a sha256sum  checksum underneath. Additionally, newer releases may also contain a downloadable SHA256SUMS file, containing the checksums of all files in that directory.

To calculate the checksum of downloaded files, and confirm that they match those in the SHA256SUMS file, the following utilities can be used:

  • On Windows, certutil -HashFile <upgrade.tar.gz> SHA256 

  • On macOS or Unix servers with Perl installed, shasum -a 256 <upgrade.tar.gz> 

  • On Unix servers with coreutils  installed, sha256sum <upgrade.tar.gz>.
