However, you can mitigate the rollover problem by getting your new code signing certificate before your old certificate expires, and then using both the old (but not yet expired!) and the new certificate to sign your code, resulting in two signatures. It's a good idea to buy your OV code signing certificate with the longest possible validity period because when you renew your certificate, the reputation will unfortunately not automatically carry over to the new certificate (not even if it's signed against the same private key as the old certificate). Source: here (Dec 2013)Ĭertificate rollover occurs when your old certificate expires and you begin signing your code with a new certificate.
The problem with OV code signing certificates is that they do not instantly silence Microsoft SmartScreen. Some CA's also offer discounts for open source projects. An OV certificate will cost you between 100 and 500 USD per year, and can also be issued to private developers without an active business license. This will also permanently, but not instantly, make the Microsoft SmartScreen warnings disappear. You can also buy a cheaper "Organization Validation" (OV) code signing certificate (also known as "standard" or "non-EV" certificates), and sign your app with that certificate.

Such an EV certificate will cost you somewhere between 250 and 700 USD per year, and will only be issued to registered businesses. Option 2: Buy an "Extended Validation" (EV) code signing certificateĪ guaranteed way to immediately and permanently get rid of the Microsoft SmartScreen warnings is to buy an "Extended Validation" (EV) code signing certificate from one of the Microsoft-approved certificate authorities (CA's), and to sign your app with that EV certificate. To overcome this problem, you'll either have to use an "Extended Validation" or an "Organization Validation" code signing certificate (see below). However, note that if you release an updated version of your app, then you'll also have to request a new review again. You need to have a Microsoft account to submit your app for review. If the review was successful, the Microsoft SmartScreen warnings will go away faster, or sometimes even instantly (it worked instantly for one of my own apps). According to Microsoft, this will help developers to "validate detection of their products".
