en-wikipedia-org-239		Certificate authority - Wikipedia			.html	text/html	5101	507	57	This market has significant barriers to entry due to the technical requirements.[5] While not legally required, new providers may choose to undergo annual security audits (such as WebTrust[6] for certificate authorities in North America and ETSI in Europe[7]) to be included as a trusted root by a web browser or operating system. On November 18, 2014, a group of companies and nonprofit organizations, including the Electronic Frontier Foundation, Mozilla, Cisco, and Akamai, announced Let's Encrypt, a nonprofit certificate authority that provides free domain validated X.509 certificates as well as software to enable installation and maintenance of certificates.[12] Let's Encrypt is operated by the newly formed Internet Security Research Group, a California nonprofit recognized as federally tax-exempt.[13] An updated W3Techs survey shows that IdenTrust, a cross-signer of Let's Encrypt intermediates,[15] has remained as the most popular SSL certificate authority, while Symantec has dropped out of the chart, due to its security services being acquired by DigiCert.	./cache/en-wikipedia-org-239.html	./txt/en-wikipedia-org-239.txt
