Welcome to the forums. I advise you not to use that file and that you delete it.
If you are an Express prospect/customer, you should use the form to access the downloadable bits. Once there, you have the ability to download software and verify that you have the proper file.
The correct file name (for a 64-bit RHEL derivative), with the proper naming convention looks like this:
centrify-suite-2017.1-rhel4-x86_64.tgz and the MD5 hash is 3D53598E7CFD1C7DB31C1A8C328E58E6
In the download site, the hash can be viewed by hovering over the download link.
The naming convention explains the suite version (e.g. centrify-suite-2017.1), the platform family (e.g. Red Hat and derivatives), the lowest version supported (version 4) and the processor architecture (x86_64). It's a tar-gzipped file that contains the RPMs and utilities.
Make sure you verify the algorithm using MD5 (e.g. like below with PowerShell)
Get-FileHash -Algorithm MD5 centrify-suite-2017.1-rhel4-x86_64.tgz Algorithm Hash Path --------- ---- ---- MD5 3D53598E7CFD1C7DB31C1A8C328E58E6
All the RPMs in that tarball are signed with Centrify's public key.
If you are a commercial customer, remember you have access to the Centrify Repos (RPM, APT and Zypper).
Since this is potentially a serious matter, with your permission, if you tell us the origin of the file, we can report this to our security department. If you downloaded the file from a compromised system, this could have caused the renaming of the file as well.
