acmetool | : lock : acmetool , an automatic certificate acquisition | TLS library

acmetool is a Go library typically used in Security, TLS, Docker applications. acmetool has no bugs, it has no vulnerabilities and it has medium support. You can download it from GitHub.

acmetool is an easy-to-use command line tool for automatically acquiring certificates from acme servers (such as let's encrypt). designed to flexibly integrate into your webserver setup to enable automatic verification. unlike the official let's encrypt client, this doesn't modify your web server configuration. :white_check_mark: zero-downtime autorenewal :white_check_mark: supports any webserver :white_check_mark: fully automatable :white_check_mark: single-file dependency-free binary :white_check_mark: idempotent :white_check_mark: fast setup. you can perform verifications using port 80 or 443 (if you don't yet have a server running on one of them); via webroot; by configuring your webserver to proxy requests for /.well-known/acme-challenge/ to a special port (402) which acmetool can listen on; or by configuring your webserver not to listen on port 80, and instead running acmetool's built in https redirector (and challenge responder) on port 80. this is useful if all you want to do with port 80 is redirect people to port 443. you can run acmetool on a cron job to renew certificates automatically (acmetool --batch). the preferred certificate for a given hostname is always at /var/lib/acme/live/hostname/{cert,chain,fullchain,privkey}.
