• Linux: certbot –apache.
• Don’t forget it you use www and not, you need to register both
• What about wildcard certs?
• You can totally do wildcard certs, but instead of just doing the acme HTTP request, they want to check a TXT DNS record to ensure you own the domain. Makes perfect sense. The problem is that every 90 days you’d have to create a new entry for renewal. Solution? API!
• Some providers have good APIs to make it easy to do that. Some (like Namecheap) may only allow you to overwrite your entire record, which means having to replace existing.
• https://github.com/scribe777/letsencrypt-namecheap-dns-auth – be careful using this in production! I wouldn’t cron it, just manually once a quarter as part of maintenance.
• Personally, since I don’t have a need for dynamic subdomains, I just manually create the certs for each subdomain I need, which also makes it easier to revoke without affecting other subdomains.

• LE on IIS? No problem!
• Win Acme: https://github.com/PKISharp/win-acme/releases/latest
• Be sure to move it out of downloads to somewhere permanent, because…
• Creates task scheduled task to run for renewal. (If it’s in Downloads, will possibly get deleted)
