Re: TLS Certificate Lifetime Now 200 Days

[Pete Helgren <pete@xxxxxxxxxx>]

No surprise there.  It's heading toward 47 days in 2029

        1. As of March 15, 2026, the maximum lifetime for a TLS 
certificate will be 200 days.
        2. As of March 15, 2027, the maximum lifetime for a TLS 
certificate will be 100 days.
        3. As of March 15, 2029, the maximum lifetime for a TLS 
certificate will be 47 days.

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....
