{"version":"1.0","type":"rich","title":"Title :: LetsEncrypt.md","description":"This example shows how to configure HTTPS certificates from Let's Encrypt across three server environments. The code demonstrates obtaining certificates via the `letsencrypt-auto` command-line tool with the `certonly --manual` flag, which requires placing a verification file on the domain. The Node.js implementation uses the `https` module with `fs.readFileSync` to load the PEM files from `/etc/letsencrypt/live/example.com/`. The Apache configuration uses `SSLCertificateFile`, `SSLCertificateKeyFile`, and `SSLCertificateChainFile` directives, while the NGINX setup relies on `ssl_certificate` and `ssl_certificate_key` directives pointing to `fullchain.pem` and `privkey.pem`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b0f9b54ec54033449e77b207334905bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
