There are millions of web sites that operates without encryption, simply due to the fact it is expensive to obtain a server certificate. Unlike HTTPS, HTTP protocol is unencrypted and anyone who wishes to eavesdrop may do so at ease. HTTPS on the other hand encrypts the communication and ensures that no third parties are diverting you from the proper destination and makes other factors like passwords, account numbers secure.
So it the secure server certificates are provided free, just like the Apache server, which most web sites operates on, many more web sites will be secure and making all our lives easier.
So EFF has teamed up with Let's Encrypt to provide no cost server certificates. Let's Encrypt is scheduled to offer free server certificates beginning in summer 2015.
"This project should boost everyday data protection for almost everyone who uses the Internet, Right now when you use the Web, many of your communications—your user names, passwords, and browsing histories—are vulnerable to hackers and others. By making it easy, fast, and free for websites to install encryption for their users, we will all be safer online." said EFF Technology Projects Director Peter Eckersley.Let's Encrypt will be overseen by the Internet Security Research Group (ISRG), a California public benefit corporation. ISRG will work with Mozilla, Cisco Systems Inc., Akamai, EFF, and others to build the much-needed infrastructure for the project and the 2015 launch.
"The Let's Encrypt certificate authority will dramatically increase the ability of websites around the world to implement HTTPS, increasing the security of hundreds of millions of Internet users every day," said Eckersley.
