this is not necessarily linked to letsencrypt, but I am using it on one of my domain and I believe this community can be very helpful to help with this question.
So I have this domain that uses letsencrypt and has Public Key Pinning (HPKP) implemented as part of strengthening the SSL strength. I did that only to have a perfect score on ssl-labs…etc
Now I want to remove that HPKP as I find it too risky in terms of handling over to another IT guy…etc And above all, not really see real value from it.
So my question is: How can I properly diffuse HPKP on that domain?
