A fully manual Let's Encrypt/ACME client
Isn’t the point of Let’s Encrypt to be automatic and seamless? Maybe, but here’s some reasons:
- You’re not comfortable with an automatic process handling something as critical, or your complex infrastructure doesn’t allow it in the first place.
- You already have perfect configuration management with something like Ansible. Renewing is a matter of dropping in a new certificate. With a manual client that works, it’s literally a minute of work.
- You want the traditional and authentic SSL installation experience of copying files you don’t understand to your server, searching for configuration instructions and praying that it works.
- Simple interface with no hoops to jump through. Keys and certificate signing requests are automatically generated: no more cryptic OpenSSL one-liners. (However, you do need to know what to do with generated certificates and keys yourself!)
- Support for DNS & HTTP validation. No need to figure out how to serve challenge files from a live domain.
- Obviously, runs without root access. Use it from any machine you want, it doesn’t care. Internet connection recommended.
- Awful, undiscoverable name.
- And finally, if the openssl binary is your spirit animal after all, you can still bring your own keys and/or CSR’s. Everybody wins.
Python 3.3 or above is required.
Using your package manager
There is a Docker image on the Docker Hub.
You can install the package from PyPI using the pip tool. To do so, run pip3 install manuale.
If you’re not using Windows or OS X pip may need to compile some of the dependencies. In this case, you need a compiler and development headers for Python, OpenSSL and libffi installed.
On Debian-based distributions, these will typically be gcc python3-dev libssl-dev libffi-dev, and on RPM-based distributions gcc python3-devel openssl-devel libffi-devel.
From the git repository
git clone https://github.com/veeti/manuale ~/.manuale cd ~/.manuale python3 -m venv env env/bin/python setup.py install ln -s env/bin/manuale ~/.bin/
(Assuming you have a ~/.bin/ directory in your $PATH).
Register an account (once):
$ manuale register email@example.com
Authorize one or more domains:
$ manuale authorize example.com DNS verification required. Make sure these records are in place: _acme-challenge.example.com. IN TXT "(some random gibberish)" Press enter to continue. ... 1 domain(s) authorized. Let's Encrypt!
Get your certificate:
$ manuale issue --output certs/ example.com ... Certificate issued. Expires: 2016-06-01 SHA256: (more random gibberish) Wrote key to certs/example.com.pem Wrote certificate to certs/example.com.crt Wrote certificate with intermediate to certs/example.com.chain.crt Wrote intermediate certificate to certs/example.com.intermediate.crt
Set yourself a reminder for renewal!
You need to create an account once. To do so, call manuale register [email]. This will create a new account key for you. Follow the registration instructions.
Once that’s done, you’ll have your account saved in account.json in the current directory. You’ll need this to do anything useful. Oh, and it contains your private key, so keep it safe and secure.
manuale expects the account file to be in your working directory by default, so you’ll probably want to make a specific directory to do all your certificate stuff in. Likewise, created certificates get saved in the current path by default.
Next up, verify the domains you want a certificate for with manuale authorize [domain]. This will show you the DNS records you need to create and wait for you to do it. For example, you might do it for example.com and www.example.com.
Once that’s done, you can finally get down to business. Run manuale issue example.com www.example.com to get your certificate. It’ll save the key, certificate and certificate with intermediate to the working directory.
There’s plenty of documentation inside each command. Run manuale -h for a list of commands and manuale [command] -h for details.
