IT service provider seeks server-side signature software

We are an IT service provider based in southern Germany and are looking for network-compatible signature software for our code signing.

It should meet the following requirements:

• Use of certificates (on USB stick) in the network for fully automated signing (batch mode) of files (e.g., PDF documents - but especially .exe and .dll files from our own software)
• Support for email signatures is not important
• Install Master must be able to access the certificates
• Use Globalsign certificate on USB stick in LAN
• Server-side, network-compatible, USB stick directly on the server or other network distributor
• It is sufficient that the solution is only designed for Windows environments

Five software workstations are planned.
