    Default Browser cipher strength

    I need to determine the cipher strength (ie 128 bit or 56 bit etc) of the user&#039;s browser. I have tried to capture this using:<BR>Request.ServerVariables("CERT_KEYSIZE") and<BR>Request.ServerVariables("HTTPS_KEYSIZE") <BR><BR>Both these commands return null. Does anybody know how to get these server variable populated?
