The application and the account information will be read from a secured
crypt file, which built on command line with runasspc or the
administrator interface runasspcadmin.
Each encrypted file receives his own password on runtime, created by
the file itself, like a finger mark.
Before runasspc start the authorized application, the application will
be checked on bit level (only exe and batch files).
Runasspc does not require an installation procedure. You only need to
copy runasspc and a cryptfile on a computer to start it directly.
Runasspc can also be run without using a cyptfile. You can call
runasspc with password in cleartext on commandline. It can be useful

request elevated privilege, the UAC dialog will pop up after you run it

new tool RunasRob
- bypass the UAC Dialog is the way of our tool RunasRob
- RunasSpc couldn’t find the application
- Set the complete path of the application in the cryptfile.
- The application must be reached for the user who calls the
application over RunaSpc because runasspc read the checksum of the
application before the application will be call under another user
- Hide start up window of RunasSpc
You can hide this window with the RunasSpc switch /quiet
RunasSpc /cryptfile:“pfad/cryptfile.spc“ /quiet
- UNC Path are supported. Mapped drives not .
The cryptfile can be on a mapped drive but not the application.
