    Issues with WIn 7, Connecting using RDP shows SHA-1 trying to Update to SHA-2


    Hello I have a system that due to software compatibily it is required to run Windows 7.I have WIndow 7 x64 ENT with SP 1 installed and as far as I can see has been fully updated with WIndows updates.I have installed the following update KB4474419 for Windows 7 x64 systems but when I try to RDP into system and look at certificate details it still shows SHA-1Trying to figure out what I need to do to update to SHA-2.

    :)

    SHA-2 Code Signing questions

    First and foremost, this is my very first experience with Code Signing.

    I bought Standard Code Signing from Certum for 3 years.

    It is SHA-2 based:

    They are all normal Windows Executables; for end users, both portable and installers.

    Questions:

    1. Bearing in mind the certificate has been issued 10. 10. 2016, i.e. after 1. 1. 2016, does this somehow influence how the signature will behave? I ask this on behalf of reading about deprecation of SHA-1, e.g.:

    2. Should I also timestamp? What is this good for? Are there any disadvantages of timestamping? I found this, which does not really clear things up:

    3. Supposing I would drop support for XP and Vista, will SHA-2 code signature work properly on Windows 7? I read on DigiCert that SHA-2 Code Signing support on Windows 7 is Partial:

    4. There is a havoc around cross-signing SHA-2 (SHA-256 in particular) and SHA-1. Supposing as I said I will no longer support WinXP and Vista, do I need this?
