Let's Encrypt is a non-profit organization whose aim is to ensure the web is secured, they are a free and automated open certificate authority who makes it possible to obtain browser-trusted certificates at no cost. The certificates provided through Let's Encrypt renew automatically unless otherwise cancelled. Because it is automated, there are no complicated setups or validation emails to approve and you can have multiple certificates installed on your hosting account, for each domain and sub-domain you choose. The certficiate is Domain-Valicated (DV) and don't require a dedicated IP. The certificates are supported by all major current browsers that support SNI.
Let's Encrypt offers the same encryption as other Domain-Validated (DV) certficiates. Let's Encrypt Certificates are all trusted by major current browsers that support SNI. It also displays a green padlock in the address bar.
The differences of Let's Encrypt:
Lets Encrypt is therefore perfect to provide a basic level of SSL encryption, however due to there being no monetary warranty for your end users, no trust seal or higher level validation, we would recommend that you only use Lets Encrypt certificates for authenticating forms, passwords or for encrypting general purpose web sites. We would continue to recommend that you use a regular SSL certificate to secure e-commerce stores and to facilitate online payment processing.
While each Let's Encrypt certificate covers a single domain, you can easily setup multiple certificates per cPanel account. This way you can have certificates for your Parked Domains, Addon Domains, and Sub-Domains all managed within cPanel.
No it does not. Let's Encrypt can be setup without the need of a Dedicated IP. However, please note that it only works with browsers that have SNI support. Viewing the site through a non-supported browser will show errors/warnings. For a list of supported browsers, please see this link.
Unfortunately not. The domain name must be registered, active, and pointed to the server. Please make sure your domain is properly resolving to the server first before setting up a Let's Encrypt certificate.
LetsEncrypt is currently supported on the majority of our hosting servers, however there are a few servers which do not currently support it. If your server supports Lets Encrypt, you will find the Let's Encrypt icon in cPanel. If you don't see the icon, unfortunately at this time your server is not supported. Early in Summer 2016, we will be upgrading our server fleet with shiny new servers which will all support Lets Encrypt - so you should expect to be able to start using Lets Encrypt by June or July.
It's easy, just follow this link for detailed instructions.
