That is one of the reasons I do not bother since long with public CAs but rather deploy my own, including own OSCP responder. Which has of course has some drawbacks like redundancy, resilience, bandwidth provision, geographical spread, implementing CA security standards and CA trust in clients. La

Revocation doesn’t remove the certificates; it just marks them as invalid when a TLS client bothers to check. -FG > On Jul 30, 2018, at 6:45 PM, David Mehler wrote: > > Hello, > > I have discovered what I believe is the issue after hearing back from > Aquamail. And that is that android 7 whic

Hello, I have discovered what I believe is the issue after hearing back from Aquamail. And that is that android 7 which I'm running 7.0 that is, only supports up to the p256 ecc curve. This brings up a question to users of letsencrypt, when you revoke a certificate does it take it out on the usage

FWIW, it’s relatively straightforward to do this with my Perl ACME implementation, Net::ACME2. You’ll get your first certificate order using one key, then request another certificate with the other key. -FG > On Jul 30, 2018, at 1:49 PM, Aki Tuomi wrote: > > I don't know how to get both RSA

Hello, What acme implementation do you use for your letsencrypt certificates? If it's acme.sh how do you get both rsa and ecc certificates? What configuration options are you using in your configuration of services to allow access to both rsa and ecc? Thanks. Dave. On 7/30/18, David Mehler wro

You should, in practice, enable both. This gives best client compability. It is possible you have clients that cannot understand ECC certificates? You can use ssl_alt_cert to provide RSA cert too. Aki > On 30 July 2018 at 20:05 David Mehler wrote: > > > Hi, > > Thanks, good news is that wor

Hi, Thanks, good news is that worked. Bad news is it all looks good which means I do not know hwhy my remote clients can't get their email, looked like from the logs it was that. Would 143 be better or 993 for the external clients? Thanks. Dave. On 7/30/18, Aki Tuomi wrote: > >> On 30 July 20
