This may not be a php question. Maybe I can do this in javascript or something, but I'm trying to figure out how to check to see what level of encryption the user's browser supports and if it's not 128 bit then I need to be able to put come kind of message notifying the user that they can't submit a credit card order.
Our credit card processer/gateway already does this, but I'd like to on the first page of the orderform (on our site) before they get to the end only to realize they have to resubmit their data after upgrading their browser.
any suggestions?
thanks in advance,
jeremy dunn
