# dehydrated [![Build Status](https://travis-ci.org/lukas2511/dehydrated.svg?branch=master)](https://travis-ci.org/lukas2511/dehydrated)

![](docs/logo.jpg)

This is a client for signing certificates with an ACME-server (currently only provided by Let's Encrypt) 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)

Current features:
- Signing of a list of domains
- Signing of a CSR
- Renewal if a certificate is about to expire or SAN (subdomains) changed
- Certificate revocation

Please keep in mind that this software and even the acme-protocol are relatively young and may still have some unresolved issues. Feel free to report any issues you find with this script or contribute by submitting a pull request.

## Getting started

For getting started I recommend taking a look at [docs/domains_txt.md](docs/domains_txt.md), [docs/wellknown.md](docs/wellknown.md) and the [Usage](#usage) section on this page (you'll probably only need the `-c` option).

Generally you want to set up your WELLKNOWN path first, and then fill in domains.txt.

**Please note that you should use the staging URL when experimenting with this script to not hit Let's Encrypt's rate limits.** See [docs/staging.md](docs/staging.md).

If you have any problems take a look at our [Troubleshooting](docs/troubleshooting.md) guide.

## Config

dehydrated is looking for a config file in a few different places, it will use the first one it can find in this order:

- `/etc/dehydrated/config`
- `/usr/local/etc/dehydrated/config`
- The current working directory of your shell
- The directory from which dehydrated was ran

Have a look at [docs/examples/config](docs/examples/config) to get started, copy it to e.g. `/etc/dehydrated/config`
and edit it to fit your needs.

## Usage:

```text
Usage: ./dehydrated [-h] [command [argument]] [parameter [argument]] [parameter [argument]] ...

Default command: help

Commands:
 --cron (-c)                      Sign/renew non-existant/changed/expiring certificates.
 --signcsr (-s) path/to/csr.pem   Sign a given CSR, output CRT on stdout (advanced usage)
 --revoke (-r) path/to/cert.pem   Revoke specified certificate
 --cleanup (-gc)                  Move unused certificate files to archive directory
 --help (-h)                      Show help text
 --env (-e)                       Output configuration variables for use in other scripts

Parameters:
 --full-chain (-fc)               Print full chain when using --signcsr
 --ipv4 (-4)                      Resolve names to IPv4 addresses only
 --ipv6 (-6)                      Resolve names to IPv6 addresses only
 --domain (-d) domain.tld         Use specified domain name(s) instead of domains.txt entry (one certificate!)
 --keep-going (-g)                Keep going after encountering an error while creating/renewing multiple certificates in cron mode
 --force (-x)                     Force renew of certificate even if it is longer valid than value in RENEW_DAYS
 --no-lock (-n)                   Don't use lockfile (potentially dangerous!)
 --ocsp                           Sets option in CSR indicating OCSP stapling to be mandatory
 --privkey (-p) path/to/key.pem   Use specified private key instead of account key (useful for revocation)
 --config (-f) path/to/config     Use specified config file
 --hook (-k) path/to/hook.sh      Use specified script for hooks
 --out (-o) certs/directory       Output certificates into the specified directory
 --challenge (-t) http-01|dns-01  Which challenge should be used? Currently http-01 and dns-01 are supported
 --algo (-a) rsa|prime256v1|secp384r1 Which public key algorithm should be used? Supported: rsa, prime256v1 and secp384r1
