I discovered that a signed installer package that is reported as correctly signed on Windows 7 and earlier, is reported as "corrupt" in IE10 on Windows 8.
Further investigation showed that the signature was made with MD5.
While it is entirely sensible that Microsoft drops support for MD5, I have been unable to find any references for this fact.
I also seem to remember seeing a notice about Microsoft removing support for MD5 in earlier versions soon, but I haven't been able to find that either.
Am I correct in thinking that MD5 is not supported on Windows 8? Do anyone have a reference for it? Will support for MD5 also be removed in Windows 7 and earlier?
