The issue here is old clients... Does anyone know how old clients would handle SHA-2 certs, would they just get a warning saying the site is insecure but still be able to visit the site over an encrypted connection or do they break completely... I guess - I'll have to run a few tests this afternoon and see how windows XP performs.
- Gregordinary 12y agoWindows XP will need Service Pack 3 to support SHA2 certs. Windows Server 2003 will require a couple manual hotfixes to get SHA2 support. http://blogs.technet.com/b/pki/archive/2010/09/30/sha2-and-windows.aspx http://blogs.technet.com/b/pki/archive/2010/09/30/sha2-and-w...

- rythie 12y agoI've seen in a lot of places that Chrome only supported SHA-2 since version 26 (2013).

However I note that this page from 2008, says Chrome supports it https://www.tbs-certificates.co.uk/FAQ/en/476.html https://www.tbs-certificates.co.uk/FAQ/en/476.html (e.g. from version 1)
