How will my user's browser look with a Let's Encrypt generated certificate?


#1

I know this question isn’t very technical, but I know different sites that use different types of SSL certs display the ‘green lock’ differently.

E.g. The login for my bank’s portal looks like this:

As opposed to the simple ‘green lock’ in the address bar for Let’s Encrypt.

So I guess my question is, what dictates the differences between these two certificates? Is there any real difference, from a security, technical perspective? I know that with some SSL cert issuers, they charge an arm and a leg for the former.

If not, can I use LE to generate the former, rather than the latter?

Thanks.

The big green bar with the company’s name in it is a so called Extended Validation certificate. In that case, the customer is checked thoroughly.

Let’s Encrypt issues domain validated certificates. The company or client who is requesting this cert isn’t checked at all. Only the domain, fully automated. This type of certificate won’t get the green bar of an EV certificate, just a green lock (if all is implemented well ofcourse.)

Ahh perfect.

This is just what I was looking for.

Thanks!
