SSL Certificates

An SSL Certificate is a document that describes who you are. Though SSL servers absolutely must provide certificates, clients--such as QS--usually don't. On rare occasions, a server will be configured to check to see if a client has a certificate. On even rarer occasions the server may require the certificate meet certain criteria. They're looking for specific certificates and specific computers. They're usually very high security organizations. Your ISP, as well as email services like gmail, yahoo, etc. won't ask for a certificate.

QS comes with a demo certificate, qs.pem, for test purposes. If you are asked for a certificate, tick Use SSL Certificate box in General Options. The demo certificate should get you through.
