Re: TLS Certificate Lifetime Now 200 Days

I actually brought your project up in a question I posted on LinkedIn
because I don't see anything else out there yet. Thought I was missing
something.

(Separately to Pete: If you publish more on your project, would love to add
a link. Didn't see anything beyond the mention so far on your site.)

Respectfully,

Daniel S. Moran

Been using LetsEncrypt for many years with a 90 day lifetime and
automated it with DCM for LetsEncrypt (https://ledcm.valadd.com/) which
I have *just* about finished for release as an open source project (just
working on documentation at this point). Maybe IBM would be interested....
