Yes, I started taking the first steps to changing the certificate
But already at the stage Complete-ACMEChallenge there were errors or I do not do those actions certificate?
When i did
New-ACMECertificate -Generate -IdentifierRef www-example-com -Alias cert-example1-domains
Submit-ACMECertificate -CertificateRef cert-example1-domains
I get
Submit-ACMECertificate : Error creating new cert :: authorizations for these names not found or expired:www.example.com
I’m sorry I’d have to take issue with the comment that ‘none of them are very complete’! Certify The Web (https://certifytheweb.com) - which is my own app for Let’s Encrypt certificate on Windows has been stable for over a year and the new v4 beta supports wildcard certs and DNS validation etc.
If you specifically need/want to script your renewal (because you have deep integration into other processes/workflows) then low-level tools like ACMESharp are invaluable. If you just want a cert for your IIS website then I’d suggest re-evaluating the high level tools available now. Even if you want to do custom scripting after your renewal the actual cert request/renewal part can be handled for you.
