A method to bypass SSL certificate name vs. host name verification via NUL ('\0') character embedded in X509 certificate's CommonName or subjectAltName was presented at Black Hat USA 2009: http://www.blackhat.com/html/bh-usa-09/bh-usa-09-archives.html#Marlinspike Similar problem affected wget (from a testing and very quick look at the code, subjectAltNames are not supported, hence only CommonName is a vector).
