This project is a Python implementation of an ACME (Automated Certificate Management Environment) client. It interacts with an ACME server to automate the process of obtaining and managing SSL/TLS certificates.

• DNS and HTTP challenge solving
• Certificate generation
• Certificate revocation

This project uses the following Python libraries:

• requests
• pycryptodome
• pyopenssl
• dnslib

To use this client, simply run the client.py script. The script will automatically handle the process of obtaining a certificate from an ACME server.

python client.py

The client can be configured through command line arguments. The available arguments are:

• dir: The directory of the ACME server.
• dns_record: The DNS record to use for DNS challenges.
• domains: The domains to obtain a certificate for.
• challenge_type: The type of ACME challenge to solve. Can be either http01 for HTTP challenges or dns01 for DNS challenges.
• revoke: Whether to revoke the certificate after obtaining it.

The obtained certificate is saved to tmp/cert.pem.

This is a basic implementation and may not include all features of the ACME protocol. It is intended for educational purposes and may not be suitable for production use.
