[wix-users] Code Signing SHA-1/2

Our signing certs have all been moved from SHA1.  However, even the latest signtool.exe will still sign with a SHA1 hash by default.  To get something other than a SHA1 hash, the /fd flag has to be passed with an appropriate hash.  For our Symantec cert, that is SHA256, SHA384, or SHA512.

I recently came across this article and I was wondering if anyone has parsed it for current best practices?


I noticed that the latest 3.11 weekly builds are still signed with SHA-1 certs and I'm wondering if that's good or not.
