How do I obtain an ECDSA certificate with Certbot?

Suppose if I need ECDSA cert do I use this command?
certbot certonly --key-type=ecdsa --elliptic-curve=secp256r1

How would you like to authenticate with the ACME CA?

1: Obtain certificates using an integrated DNS server (dns-standalone)
2: Spin up a temporary webserver (standalone)
3: Place files in webroot directory (webroot)

I use 1 for wildcard certs.

After setting --key-type=ecdsa on the command line, you can obtain your certificate just like you would normally. There's more documentation about obtaining ECDSA certificates with Certbot at


There is no info about ECDSA on that page.

You need to force-refresh it to get the updated page, same thing happened to me.
