Hi Amax, Try this SDK which is supposed to contain certutil.exe as well: http://www.microsoft.com/downloads/details.aspx?FamilyID=860ee43a-a843-462f-abb5-ff88ea5896f6&displaylang=en But I can't imagine end-users dealing with such a horrible tool. This is for *cryptopgraphers* only. Making a Chinese Firefox distribution should be a more workable solution.
