Script to install a .cer

Is there a script or a way to remotely install a .cer self signed.  I know you can via a GPO but I have so many I really would rather make this a one time install.

Below is a small PSexec script that will copy certmgr.exe from a network location to your target machine and then run the certmgr.exe tool. Downlaod PStools and run this BAT file from within that folder.


@echo off
set /p var= Enter Computer Name:
set /p var2= Enter username:
set /p var3= Enter Password:

psexec -u domain\%var2% -p %var3% \\%var% cmd /c copy "\\uncpath\test.cer" C:\
psexec -u domain\%var2% -p %var3% \\%var% cmd /c copy "\\uncpath\certmgr.exe" C:\

psexec -u domain\%var2% -p %var3% \\%var% cmd /c c:\certmgr.exe -add C:\test.cer -s -r localMachine root

If you are using multiple internal self-signed certs, consider implementing a Certificate Authority. Properly implemented, clients will automatically trust most certs issued from the CA (code signing certs is one example where this is not the case, they still have to be imported to the local trust store on clients).

I have done this before with a batch file. It is very simple command is below.

certmgr.exe -add C:\test.cer -s -r localMachine root

Certmgr.exe is not installed by default on XP machines so you will need to have it on the machine before you can use it.
