letsencrypt/acme client implemented as a shell-script
letsencrypt/acme client implemented as a shell-script, just add water. Dehydrated is a client for signing certificates with an ACME-server (e.g. Let’s Encrypt or ZeroSSL) implemented as a relatively simple bash script. It uses the OpenSSL utility for everything related to actually handling keys and certificates, so you need to have that installed. Other dependencies are cURL, sed, grep, mktemp (all found on almost any system, cURL being the only exception). Please keep in mind
