 This is for whomever manages the mission files on the ArmA servers.
I will attempt to explain how to sign mission pbo files that you upload to mpmissions so that we can make sure nobody is hacking the server with modified missions.

To start, you need the DSSignFile.exe tool that comes with binPBO. It will sign your pbo file. You can use the binPBO tool if you are making pbo files from mission folders, but if you are just signing the pbo you use DSSignFile.exe directly.
You can get it from HERE
You also need OUR server key. You need to get the specific server key (101st.biprivatekey) from the ftp parent arma directory.
Probably the best thing is to just copy the pbo file to the DSSignFile folder and do it like this:
Code:

C:Program Files (x86)Bohemia InteractiveToolsBinPBO Personal EditionDSSignFile>dir
 Volume in drive C has no label.
 Volume Serial Number is E648-F010

Upload the pbo file AND the *.bisign created key to the mpmissions folder.
With the server configured to used signed keys, it now checks to make sure that the pbo file on the server is the same one the player downloads.
