TLS certificates

Free where free is correct, paid where paid is

Every service here gets a certificate at no charge, issued and renewed automatically. The paid range exists for the three cases where an automatic certificate is not what you need, and this page says which three.

What it does, and what it does not

What a certificate does

  • Encrypts the connection, so what is sent cannot be read in transit.
  • Proves the connection reached the name in the address bar and not somewhere else.
  • Lets the browser use HTTP/2 and HTTP/3, which it will not do without one.
  • For an organisation-validated certificate, says who holds the name.

What it does not do

  • It does not make the application behind it secure. A certificate is about the pipe, not what is in it.
  • It does not stop a visitor being phished. An attacker can get a certificate for their own name in minutes.
  • It does not improve search ranking in any way worth paying for.
  • A more expensive certificate does not encrypt more strongly. The cipher is the same.

Questions we are asked

Then why would I pay for one?

Three reasons. A contract or an auditor requires organisation validation; you need one certificate covering many unrelated names with a warranty attached; or you are on a platform that cannot do automatic renewal and you want a long-lived file.

Is the free certificate less secure?

No. The encryption is identical. What differs is what was checked before it was issued, and for most sites what was checked is control of the name, which is all a browser cares about.

What happens when it expires?

Renewals are automatic, with a reminder thirty days ahead and again at seven.

Can I bring my own certificate?

Yes, on any service, and the private key stays where you put it.
