I have a working system of client certs (which were signed using SHA1) allowing access to a private area on a website. As we all know, soon such certs will be a thing of the past since SHA2 will be required.

I have started generating the certs with SHA2, but want to know if can I use both systems on the same site while I get my users to transition to their new certs.

Thanks a heap!

Best regards,
