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?
