Other than Windows XP pre-SP3, does anyone have a list of operating systems and/or devices that will have a problem with SHA-256 certificates? I tried loading https://cert-test.sandbox.google.com/ https://cert-test.sandbox.google.com/ in Android 2.3, the earliest version of Android that I care about. This is an OS that has given me much pain because it doesn't support SNI. So I was pleasantly surprised to find that it recognizes the SHA-256 certificate just fine. What about OSX and iOS?
