Let’s Encrypt will be reducing the validity period of the certificates we issue. We currently issue certificates valid for 90 days, which will be cut in half to 45 days by 2028.
This change is being made along with the rest of the industry, as required by the CA/Browser Forum Baseline Requirements, which set the technical requirements that we must follow. All publicly-trusted Certificate Authorities like Let’s Encrypt will be making similar changes. Reducing how long certificates are valid for helps improve the security of the internet, by limiting the scope of compromise, and making certificate revocation technologies more efficient.
Ours is automated, but we incur downtime on the renewal because our org forbids plain http so we have to do TLS-ALPN-01. It is a short downtime. I wish let’s encrypt would just allow http challenges over https while skipping the cert validation. It’s nuts that we have to meaningfully reply over 80…
Though I also think it’s nuts that we aren’t allowed to even send a redirect over 80…
Hot take: for-profit orgs should be buying TLS certificates from the CA cartel instead of using Let’s Encrypt. Unless you’re donating to LE, and in that case it’s cool.
is redirecting http to https also out of the question? because let’s encrypt HTTP-01 accepts http -> https redirects:
They in fact refuse to even do a redirect… it’s monumentally stupid and I’ve repeatedly complained, but ‘security’ team says port 80 doing anything but dropping the packet or connection refused is bad…
Can’t use DNS?
The same screwed up IT that doesn’t let us do HTTP-01 challenges also doesn’t let us do DNS except through some bs webform, and TXT records are not even vaguely in their world.
It sucks when you are stuck with a dumber broad IT organization…
Yikes. I feel for you man.
