ItРІР‚в„ўs perfectly possible to upgrade a 64-bit version of Windows 2008 server all the way through to Windows 2016 server if you need to. Ideally your Certificate Authorities should be running the newest version of Windows Server possible, and IРІР‚в„ўd strongly suggest a bare minimum of Windows 2012 to cover all bases. This should apply to most modern systems that are kept reasonably up-to-date, but РІР‚Сљmost modern systemsРІР‚Сњ isnРІР‚в„ўt the same as РІР‚СљallРІР‚Сњ, so make sure youРІР‚в„ўve checked this before starting work. You should also review appliances and applications on your network that use certificates issued by your CAs and ensure that they can handle the update to SHA2. There is a hotfix available but if this describes your environment then certificate hashes are probably the least of your security worries.

If youРІР‚в„ўre using Windows XP machines and Windows 2003 servers then you will have problems with SHA2 certificates. While IРІР‚в„ўm actually quite confident that the processes I outline below are robust and that the articles I link to are good, well written articles from knowledgeable people, you will still to be able to understand the concepts weРІР‚в„ўre talking about and be able to adopt instructions to your environment before starting the upgrade process.Р”Р‡irst of all, you need to examine your environment. If this doesnРІР‚в„ўt describe you then I strongly advise you to get help, hire a consultant if need be, before proceeding. IРІР‚в„ўm assuming that youРІР‚в„ўre fairly knowledgeable and comfortable with manipulating certificates, and understand basic processes around managing private Windows CAs on your network. The steps you need to perform to actually complete the upgrade are extremely simple but the preparation you should carry out beforehand needs to be painstakingly done. In a lot of ways, this really isnРІР‚в„ўt difficult at all. IРІР‚в„ўm going to discuss the methods I use, which are designed for a Windows PKI infrastructure with several levels (a root CA and subordinate РІР‚СљissuingРІР‚Сњ CAs). Job doneРІР‚В¦ (though as ever the devil is in the details).Р”Р‡or those who are running a Windows Certificate Authority (CA) to issue private certificates to servers and devices on your network, there is potentially a different problem: How do you ensure that your private CA is able to issue SHA2 certificates, and if not, how do you upgrade it so that it can?

certificates you purchase from a public Certificate Authority, aka РІР‚СљCAРІР‚Сњ, online) is actually fairly easy buy a new certificate from a competent supplier, install it, remove old certificate. Upgrading your public facing websites and services that use public certificates (e.g.

There are some good introductory articles on the entrust website that talk about this issue, but please note that these articles are from 2014 and somewhat understand the urgency of the issue. If youРІР‚в„ўre not aware of these risks then please look around. In fact, my use of РІР‚СљnowРІР‚Сњ kinda understates the point you should be urgently looking to upgrade to SHA2 if you have any devices or servers using certificates. As IРІР‚в„ўm sure most of us know by now, SHA1 cryptography hashes have been increasingly under attack, and are now regarded as fully broken.
