The CA I'm working with is Let's Encrypt!

Just to be clear... this is for the IBM i as the CLIENT, not the server.
Our external FTP server is hosted somewhere in the fog (I mean cloud), and is using Let's Encrypt to auto-renew the certificate before it expires every 90 days (it has yet to work). I just need the IBM i to accept the new cert from within the FTP client.

I have the root certificates installed and enabled, but they expire in 2025.

Subject: Re: CA Certificates


Been corresponding with some DCM friends at IBM today.   Right now there
isn't a way through DCM to automatically renew certificates.  However,
if you have a manual method of reminding you to renew and then renew the
certificate manually, you can use the "renew" feature in the old DCM to
renew the certificate.  The easiest way, for me at least, is to continue
to use the original CSR that DCM generated when you requested the
certificate in the first place.  Renewing every time with the same CSR
allows you to just take the "renew" option in the old DCM and point to
where in the IFS the renewed certificate resides.

In the new DCM, if you are using the same CSR, you take the "import"
option (not the renew option on the "View Certificate" page) and just
import the renewed certificate.  Again, the caveat is that you are using
the original CSR for the certificate. Remember that IF you want generate
a NEW CSR, then you add one renewal step of first generating and copying
in the CSR and then requesting the renewal on the cert (all manual) and
then import the certificate (in the new DCM) or use the "Renew" step in
the old DCM.

There are semi-automated methods using LetEncrypt or other ACME based
clients as well.  Jesse Gorzinski has a project in github:
https://github.com/ThePrez/DCM-tools  ; There are also some PASE
utilities that can leverage LetEncrypt.  I am trying to complete a
project that makes the renewal fully automatic in DCM.   Just have to
sort out my  issues with the renewal API.....

Just wondering the best/easiest way to handle keeping CA certificates renewed/current.

I thought in the old DCM there was a way to auto-renew, or at least click a button to renew the CA?
