As you may know encryption of internet traffic have become a common practice for websites and applications. Sending information in plain (human readable) text is a thing that should be frowned up on and should be a thing of the past. When visiting website with a browser, take Google Chrome as an example, you can tell if the website’s traffic is encrypted or not. As you can see when visiting this blog a green little padlock will appear before the URL. This means that the website’s traffic is encrypted. Which means that all information you send to the website or the website sends to you will be encrypted, non readable.
As a common practice, all traffic sent over the port 443 will be encrypted. You can tell that you are using port 443 by looking at the URL in your browser. If the URL starts with “https” instead of “http” that means that the website is using the “https” protocol and your browser is speaking to the website through port 443.

Let’s Encrypt is a public benefit organization started by the Internet Security Research Group (ISRG) in California.
Let’s Encrypt main goal is to make it possible to encrypt “everything” without any complications. Let’s Encrypt will be absolutely free, aims to be automatic, advocates security, open (as in free/open software) and community driven. Let’s Encrypt is backed up by big names such as, Linux Foundation, Mozilla, Cisco, EFF, IdenTrust and many more.

Let’s Encrypt will issue free SSL certificates that is trusted and supported by the major browsers. Let’s Encrypt has as from 20th October been trusted by the major certificate authority IdenTrust. This means that Let’s Encrypt can issue trusted SSL certificates for free. This is a big milestone for the security of the internet. Being able to use trusted certificates for any domain that you own for free is a thing that shouldn’t be a complication. It shouldn’t be a matter of cost to be able to encrypt information whatsoever.

Let’s Encrypt aims to be available the last quarter of 2015 and everyone should be able to take part in it. You can read more about Let’s Encrypt over at https://letsencrypt.org/
If you visit https://helloworld.letsencrypt.org/ you can have a look at the first issued certificate by Let’s Encrypt.

UPDATE:
As you can see I have now a SSL certificate issued by “Let’s Encrypt Authority X1”!
