Subject: null-prefix certificate for paypal



If there's really a Moxie Marlinspike fan club [1], I'm definitely a member..  Attached is one of the null-prefix certificates [2] that he distributed during his "intercepting secure communication" training at Black Hat.  This one's for www.paypal.com, and since the Microsoft crypto api appears to remain unpatched, it works flawlessly with sslsniff [3] against all clients on Windows (IE, Chrome, Safari).  Also, because of Moxie's attacks against OCSP [4], I don't think this certificate can be revoked.

Enjoy!
