Acme PHP is a simple yet very extensible CLI client for Let's Encrypt that will help you get and renew free HTTPS certificates.
Acme PHP is also an initiative to bring a robust, stable and powerful implementation of the ACME protocol in PHP. Using the Acme PHP library and core components, you will be able to deeply integrate the management of your certificates directly in your application (for instance, renew your certificates from your web interface). If you are interested by these features, have a look at the acmephp/core and acmephp/ssl libraries.
Acme PHP is now maintained by https://zerossl.com.
Acme PHP provides several major improvements over the default clients:
- Acme PHP comes by nature as a single binary file: a single download and you are ready to start working ;
- Acme PHP is based on a configuration file instead command line arguments. Thus, the configuration is much more expressive and the same setup is used at every renewal ;
- Acme PHP is very extensible it to create the certificate files structure you need for your webserver. It brings several default formatters to create classical file structures (nginx, nginx-proxy, haproxy, etc.) but you can very easily create your own if you need to ;
- Acme PHP follows a strict BC policy preventing errors in your scripts or CRON even if you update it (see the Backward Compatibility policy of Acme PHP for more informations) ;
Read the official Acme PHP documentation.
Acme PHP follows a strict BC policy by sticking carefully to semantic versioning. This means your scripts, your CRON tasks and your code will keep working properly even when you update Acme PHP (either the CLI tool or the library), as long as you keep the same major version (1.X.X, 2.X.X, etc.).
The Acme PHP test suite uses the Docker Boulder image to create an ACME server.
To launch the test suite, you need to setup the proper Docker environment for the suite.
Useful scripts are available under the tests directory: in the Acme PHP root directory,
execute the following:
# Create the Docker environment required for the suite
sudo tests/setup.sh
# Run the tests
tests/run.sh
# Clean the docker environment
tests/teardown.sh
Note: you may have boulder errors sometimes in tests. Simply ignore them and rerun the suite, they are due to an issue in the container DNS.
Warning: as the acmephp/testing-ca Docker image needs to be mapped to the host network, you may have ports conflicts. See https://github.com/acmephp/testing-ca for more informations.
The run command is an all in one command who works with a domain
config file like
contact_email: contact@company
key_type: RSA # RSA or EC (for ECDSA). Default "RSA"
defaults:
distinguished_name:
country: FR

organization_name: MyCompany
solver: http
certificates:
- domain: example.com
distinguished_name:
organization_name: MyCompany Internal
solver: route53
subject_alternative_names:
- '*.example.com'
- www.subdomain.example.com
install:
- action: install_aws_elb
region: eu-west-1
loadbalancer: my_elb
- domain: www.example.com
solver:

# port: 21
# passive: true
# ssl: true
# timeout: 30
# privateKey: path/to/or/contents/of/privatekeyusage
$ acmephp run path-to-config.ymlYou can also use the docker image to generate certificates.
Certificates and keys are stored into the volume /root/.acmephp
docker run --rm -ti -v /cache/.acmephp:/root/.acmephp -v $PWD/.config.yml:/etc/acmephp.yml:ro acmephp/acmephp:latest run /etc/acmephp.yml
