[Byte-ul]

Another Big Milestone – Let's Encrypt is now offering Free HTTPS certificates to everyone.

Let's Encrypt has opened to the public, allowing anyone to obtain Free SSL/TLS (Secure Socket Layer/Transport Layer Security) certificates for their web servers and to set up HTTPS websites in a few simple steps (mentioned below).

Let's Encrypt – an initiative run by the Internet Security Research Group (ISRG) – is a new, free, and open certificate authority recognized by all major browsers, including Google's Chrome, Mozilla's Firefox and Microsoft's Internet Explorer.

The Free SSL Certification Authority is now in public beta after testing a trial among a select group of volunteers.

Why Let's Encrypt?

Let's Encrypt promised to offer a certificate authority (CA) which is:

• Free – no charge for HTTPS certs.
  
• Automatic – the installation, configuration as well as the renewal of the certificates do not require any administrator action.
  
• Open – the automatic issuance, as well as renewal procedures, will be published as the open standard.
  
• Transparent – the records of all certs issuance or revocation will be available publicly.
  
• Secure – the team is committed to being a model of best practice in their own operations.
  
• Cooperative – Let's Encrypt is managed by a multi-stakeholder organization and exists to benefit the community, not any of the consortium members.

…

listen 443 ssl;

FREE HTTPS Certificates for Everyone!

So, now it's time for the Internet to take a significant step forward in terms of security and privacy. With Let's Encrypt, the team wants HTTPS becomes the default and to make that possible for everyone, it had built Let's Encrypt in such a way that it is easy to obtain and manage.

"There's a reward going for anyone who can find a security hole in the service," the team wrote in a

blog post

. "We have more work to do before we're comfortable dropping the beta label entirely, particularly on the client experience."

"Automation is a cornerstone of our strategy, and we need to make sure that the client works smoothly and reliably on a wide range of platforms. We'll be monitoring feedback from users closely, and making improvements as quickly as possible."

Let's Encrypt had signed its first free HTTPS certificate in September, and its client software emerged in early November. Since then the team has been finding flaws in their systems before going public.
