Old OSs signing and driver configuring issue
Posted: Tue Aug 20, 2019 10:37 am
Could you please help us in such issue:
We use MadCodeHook for loading of 3 DLLs. It has to work on Windows from XP to Win 10.
For driver signing we use sha1 digital cert. But our sha1 cert will expire in a few days. So we will have to sign by sha256 soon and it will not work at XP and Vista.
Of course we can sign driver now, while sha1 cert is actual, but when we will change DLLs in a future, they will sign by sha256 cert. Will it work?
Are there any solutions for such issue? How can we change DLLs without having to reconfigure and sign the driver?
Or maybe there is some other solution to our problem?
Thank you in advance!
