Removing certificates

[EarthQ]

Hi folks,

Is it possible to remove the certificate from a signed file?
Thanks in advance.

Yes if it is exe / dll / mui. Haven't found a way to do it with cabs yet.

There is an API function in desktop windows that can do it: ImageRemoveCertificate (http://msdn2.microsoft.com/en-us/library/ms680214.aspx). So if you can code in any language that can use Win32 APIs you can make a small app to do it.
I've been meaning to write one my self but never got the time.

Alternatively someone may have done this already try google.

May be it is time to create usigner.exe?
