Hi Everyone,

Our Let's Encrypt certificate is going to expire in about a week. The web 
server uses a RSA keypair. I think we are at the point we can rotate the 
RSA key out for an EC based key.

However, ECDSA did not become part of a standard until 2008 or so. That 
means we drop compatibility for pre-2008 clients if anyone is using an 
antique client. Based on my experience with XP testing (yes, we still test 
it), IE 6 can't do anything with the newer protocols and RSA keys so it 
does not matter what key type we use. Antique clients are simply broke.

Are there any objections to switching to an EC key?

Jeff
