Question

I want to codesign an .exe file using an API rather than running signtool.exe. The documentation for SignerSignEx is here:

http://msdn.microsoft.com/en-us/library/aa387734(VS.85).aspx

It seems to be recommended as a modern replacement for the CapiCom library, based on this documentation:

http://msdn.microsoft.com/en-us/library/aa375732(VS.85).aspx#_crypto2_digital_signature_objects

Is there any sample code somewhere for how to use it?

Answer 1

You can find a simple enough sample here in Alejandro Campos Magencio’s post.
It begins with CAPICOM, but fear not, the second half is about SignerSignEx. It also ends with a troubleshooting tip.

I’ve always used signtool.exe myself. Are you having any issues with it?
