acme-tiny is a tiny script to issue and renew TLS certs from Let's Encrypt . This is a tiny, auditable script that you can throw on your server to issue and renew Let's Encrypt certificates. Since it has to be run on your server and have access to your private Let's Encrypt account key, the script is kept as tiny as possible (currently less than 200 lines). The only prerequisites are Python and openssl.
