  1. IE Encryption Check (1 messages)

    My requirement is to display alert if the browser is not supported with 128 bit encryption.So whenever I display the content, browser encryption will be checked and it will throw alert if it(128 bit) is not supported by browser.
    This works perfectly for Netscape(using navigator.userAgent) and not for IE. Is there any way we can find out this?

    I would really appreciate if you would help me on this.

    From IE 5.5 128 bit encryption is standard.
    Before that it required a special addon pack that cannot be simply detected as it doesn't change the browser itself.

    So if you see a version >= 5.5 you can be certain it's got 128 bit encryption, with lower versions there's no easy way (unless you hack into the SSL layer of the webserver in some way).
