+
+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)
+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
-If you want to import existing keys from the official letsencrypt client have a look at [Import from official letsencrypt client](https://github.com/lukas2511/letsencrypt.sh/wiki/Import-from-official-letsencrypt-client).
+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:
-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 pullrequest.
+- `/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: ./letsencrypt.sh [-h] [command [argument]] [parameter [argument]] [parameter [argument]] ...
+Usage: ./dehydrated [-h] [command [argument]] [parameter [argument]] [parameter [argument]] ...
Default command: help
Commands:
+ --register Register account key
--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:
+ --accept-terms Accept CAs terms of service
+ --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!)
+ --lock-suffix example.com Suffix lockfile name with a string (useful for with -d)
+ --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.sh Use specified config file
+ --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
```
-
-### domains.txt
-
-The file `domains.txt` should have the following format:
-
-```text
-example.com www.example.com
-example.net www.example.net wiki.example.net
-```
-
-This states that there should be two certificates `example.com` and `example.net`,
-with the other domains in the corresponding line being their alternative names.
-
-### $WELLKNOWN / challenge-response
-
-Boulder (acme-server) is looking for challenge responses under your domain in the `.well-known/acme-challenge` directory
-
-This script uses `http-01`-type verification (for now) so you need to have that directory available over normal http (no ssl).
-
-A full URL would look like `http://example.org/.well-known/acme-challenge/c3VjaC1jaGFsbGVuZ2UtbXVjaA-aW52YWxpZC13b3c`.
-
-An example setup to get this to work would be:
-
-nginx.conf:
-```
-...
-location /.well-known/acme-challenge {
- alias /var/www/letsencrypt;
-}
-...
-```
-
-config.sh:
-```bash
-...
-WELLKNOWN="/var/www/letsencrypt"
-...
-```
-
-An alternative to setting the WELLKNOWN variable would be to create a symlink to the default location next to the script (or BASEDIR):
-`ln -s /var/www/letsencrypt .acme-challenges`
-
-### dns-01 challenge
-
-This script also supports the new `dns-01`-type verification. Be aware that at the moment this is not available on the production servers from letsencrypt. Please read https://community.letsencrypt.org/t/dns-challenge-is-in-staging/8322 for the current state of `dns-01` support.
-
-You need a hook script that deploys the challenge to your DNS server!
-
-### Elliptic Curve Cryptography (ECC)
-
-This script also supports certificates with Elliptic Curve public keys! Be aware that at the moment this is not available on the production servers from letsencrypt. Please read https://community.letsencrypt.org/t/ecdsa-testing-on-staging/8809/ for the current state of ECC support.
