Hi, It looks like I need to learn a lot more about security protocols - secured certificates and browser encryption so that I can understand how to deal with this stuff. I know there is the settings in the ssl vhost that I can look at and PHP gives me some information such as : [SSL_PROTOCOL] => TLSv1.2 [SSL_SECURE_RENEG] => true [SSL_COMPRESS_METHOD] => NULL [SSL_CIPHER] => ECDHE-RSA-AES128-GCM-SHA256 [SSL_CIPHER_EXPORT] => false [SSL_CIPHER_USEKEYSIZE] => 128 [SSL_CIPHER_ALGKEYSIZE] => 128 Which I think is the server / ssl cert config not the client. Any suggestions on how I might learn this stuff without spending endless hours fumbling around in the dark for a while? Basically what I want to do is test the client browser to verify it is capable of 2048bit encryption using PHP and / or JavaScript and pop up a messages if the browser is not capable. Thank you so much for your help!!
