PHP and SSL? How can I check for it?

[jnuneznyc]

Via PHP, How can I tell if the client is connected via SSL? Also can you check for the strength? If it's 128 bit?

Thanks

There are a whole bunch of $_SERVER vars that you can look at.
Briefly:

_SERVER["HTTPS"] - is set if the SSL is on
_SERVER["SSL_CIPHER_USEKEYSIZE"] - bit strength of the browser.
_SERVER["SSL_CIPHER_ALGKEYSIZE"] - bit strength of the server.

var_dump($_SERVER); - will display all of the _SERVER vars for the current page.

THANKS for the quick response!

I'll check it out as soon as I get the new server up and running.
