Microsoft announced that starting from January 1, 2016, software signed with certificates which use SHA-1 algorithm will no longer be treated as digitally signed. Meaning it will display various warnings when you try to install such software. Older builds, timestamped before 1st January will continue to work.
I’ll link to discussion on BOS about this subject:
However I don’t see that it’s enforced yet. Tried to install new release of CCProxy on Win 8.1 and Win 10 and it works without any warnings. I can see digital signature, that it’s SHA-1 and timestamped in 2016 and there are no problems yet. Does anyone else see this issue with new builds and SHA-1?
