This program was installed as part of a software program that uses a USB security 'hardware key' ie jumpdrive; it runs at a high priority even when its application is not running
it is related to "Sentinel key" by Safenet inc. the software use a hardware dongle to protect a third party software from piracy
It is a sentonal key USB dongle program, commonly used with Lenel security softwre
I dont know alot about it but I secureli delete it after it uses 13% of my core i7 its impossible for such a program i think, therefore we have an antivirus
I uninstalled the program from the Control Panel, but it didn't go away and stop slamming my processors until I disabled the "Sentinel Keys Server" (by SafeNet, Inc.) service from Computer Management
It's for a security hardware dongle for a high end professional CAD program I've purchased. Uses more resources than I'd like even when that proggy isn't running, but only briefly. Not dangerous although AVs and Firewalls hate it.GraphiCode uses it for their applications.
Installs with CitectSCADA for Sentinel Hardware Key (USB License Dongle for CitectSCADA runtime). It is not required if you are not using a hardware dongle--such as on a development PC running runtime only in demo mode. Expect it installs with any other software using Sentinel's hardware keys as well. It was running one core on a core i4 PC at 100% continuously causing fan to run at max on Windows 7 Dell (in past experience, it typically uses 0% CPU). Stopped service and set to manual start as I do not need it on this development PC. Problem solved.

sntlkeyssrver or sentinal keys server is used by programs like (in my case) lightwave. very anoying when not using the 3D program so i just stop it running in task manager if i dont use lightwave.
Takes up way o much processor time
Wird benötigt für USB-Dongel, z.B. Videoschnittsoftware "EDIUS 6.XX, VisTitle". Ist ohne USB-Dongel "stopped"

Best practices for resolving sntlkeyssrvr issues

A clean and tidy computer is the key requirement for avoiding problems with sntlkeyssrvr. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
