## What it is
A tiny, auditable Python script (under 200 lines) that issues and renews TLS certificates from Let's Encrypt using the ACME protocol. It requires only Python and OpenSSL and is designed to be run directly on your server with your private account key.

## Use cases
- issue let's encrypt certificates from a minimal script
- automate tls certificate renewal on my server
- auditable alternative to certbot
- renew ssl certs with a cron job
- get https certificates without installing a heavy client
- manage let's encrypt certs with only python and openssl

## When to choose
- you want a minimal, auditable ACME client you can read in one sitting
- you already understand ACME basics and just need cert issuance/renewal
- your server has only Python and OpenSSL available
- you want to script renewals via cron with full control

## When to avoid
- you want automatic webserver configuration or guided setup
- you need support for wildcard certificates or DNS challenges
- you're not comfortable managing account keys and CSRs manually
- you want a client with plugins for many web servers and DNS providers
