A Dutch Certificate Authority (CA) that issues SSL (Secure Sockets Layer) and EVSSL (Extended Validation) certificates, which help to ensure the websites visited by users when Web browsing are authentic rather than fake websites masquerading as legitimate sites. In July 2011, DigiNotar was hacked by a certificate bandit, which was able to issue fraudulent certificates through the company for a fake Google web site as well as several dozen other sites.
