I am working on a credit card support module on a Java-based Web application, for security, we want to have the users use TLS v1.2 supported browsers while viewing the credit card pages How do I make sure they are compatible? Note: We don't want to restrict users to other pages if they are not compatible.
This is an old question. Here's some information
How do I detect the TLS version of an HttpServletRequest?
Can I detect the SSL version that a browser supports?
