PinTool is a PIN Input Typing Assistant™ (PITA), that automates typing your PIN when code-signing a Windows binary using a Hardware Security Module (HSM), e.g. a YubiKey.

1. Open the Command Prompt for VS (Visual Studio).

2. Run the Program Maintenance Utility (NMAKE) to build PinTool:

   nmake

3. Done! There wasn't even time to get a coffee or a tea...

When code-signing a binary add PinTool just before SignTool, e.g.:

start pintool.exe 123456
signtool sign /v /n "My Company" /a /fd sha256 /tr "http://ts.ssl.com" /td sha256 my_binary.exe

Replace 123456 with your PIN, or maybe with an environment variable holding your PIN.

This will start PinTool in the background, and then immediately return and run SignTool. As soon as the Windows Security dialog is detected by PinTool, it will start "typing" your PIN and then hit the enter key, after which PinTool will terminate.

If your automated build script calls SignTool multiple times, then you should add PinTool before each SignTool call.
