-## 1. About -µPki [maɪkroʊ ˈpiː-ˈkeɪ-ˈaɪ] is a small PKI in python that should let you make basic tasks without effort. -It works in combination with: -> - [µPKI-RA](https://github.com/proh4cktive/upki-ra) -> - [µPKI-WEB](https://github.com/proh4cktive/upki-web) -> - [µPKI-CLI](https://github.com/proh4cktive/upki-cli) - -µPki is the Certification Authority that is invoked by the [µPKI-RA](https://github.com/proh4cktive/upki-ra) Registration Authority. - -### 1.1 Dependencies -The following modules are required -- PyMongo -- Cryptography -- Validators -- TinyDB -- PyYAML -- PyZMQ - -Some systems libs & tools are also required, make sure you have them pre-installed +# uPKI CA Server + +[![Python Version](https://img.shields.io/pypi/pyversions/upki-ca)](https://pypi.org/project/upki-ca/) +[![License](https://img.shields.io/pypi/l/upki-ca)](LICENSE) +[![Docker Image](https://img.shields.io/docker/v/upki-ca/ca-server?label=docker)](https://hub.docker.com/r/upki-ca/ca-server) + +A production-ready Public Key Infrastructure (PKI) and Certificate Authority system with native ZeroMQ protocol support for secure, high-performance certificate operations. + +## Overview + +uPKI CA Server is a modern PKI implementation designed for scalable certificate lifecycle management. It provides a complete Certificate Authority solution with support for certificate generation, signing, revocation, CRL management, OCSP responses, certificate profiles, and administrative management. + +Built on ZeroMQ (ZMQ) for reliable, asynchronous communication, uPKI offers two dedicated ports: + +- **Port 5000**: CA operations (certificate signing, revocation, CRL generation, OCSP) +- **Port 5001**: RA (Registration Authority) registration endpoint + +## Key Features + +- **Certificate Authority Operations** — Generate Root CA and Intermediate CA certificates with full PKI hierarchy support +- **Certificate Signing** — Process Certificate Signing Requests (CSRs) with configurable key types and algorithms +- **Revocation Management** — Revoke certificates and generate Certificate Revocation Lists (CRL) +- **OCSP Support** — Built-in Online Certificate Status Protocol responder for real-time certificate validation +- **Certificate Profiles** — Define and enforce certificate templates with custom extensions, key usage, and validity periods +- **Administrative Management** — Manage CA administrators with role-based access control +- **ZMQ Protocol** — Native ZeroMQ messaging for reliable, asynchronous CA operations +- **Multiple Storage Backends** — File-based storage (default) and MongoDB support +- **Docker Deployment** — Production-ready Docker image for easy containerized deployment + +## Requirements + +- **Python**: 3.11 or higher +- **Dependencies**: + - `cryptography` — cryptographic operations + - `pyyaml` — configuration management + - `tinydb` — embedded document database + - `zmq` — ZeroMQ messaging + +## Installation + +### From PyPI + ```bash -sudo apt update -sudo apt -y install build-essential libssl-dev libffi-dev python3-dev python3-pip git +pip install upki-ca ``` -## 2. Install -The Installation process require two different phases: +### From Source -1. clone the current repository ```bash -git clone https://github.com/proh4cktive/upki -cd ./upki +# Clone the repository +git clone https://github.com/circle-rd/upki.git +cd upki + +# Install dependencies +pip install -e . ``` -2. Install the dependencies and upki-ca service in order to auto-start service on boot if needed. The install script will also guide you during the setup process of your Registration Authority (RA). +### Development Installation + ```bash -./install.sh +# Install with development dependencies +pip install -e ".[dev]" + +# Run the test suite +pytest + +# Run with coverage report +pytest --cov=upki_ca --cov-report=html ``` -If you plan to use two different servers for CA & RA (recommended) you can specify on which ip:port your CA should listen. +## Quick Start + +### 1. Initialize the PKI + ```bash -./install.sh -i 127.0.0.1 -p 5000 +python ca_server.py init ``` -## 3. Usage -The Certification Authority (CA) is not designed to be handled manually. Always use the Registration Authority (RA) in order to manage profile and certificates. +This creates the Root CA with default configuration. You can customize the CA by editing the configuration file. + +### 2. Register a Registration Authority (RA) -If needed you can still check options using ```bash -./ca_server.py --help +# Register an RA in clear mode (for initial setup) +python ca_server.py register ``` -## 3.1 RA registration -Certification Authority can not run alone, you MUST setup a Registration Authority to manage certificate. *The current process generates a specific RA certificate in order to encrypt the communication between CA and RA in near future, but this is not currently set!* -Start the CA in register mode in order to generate a one-time seed value that you will have to reflect on your RA start +### 3. Start the CA Server + ```bash -./ca_server.py register +# Start the CA server in TLS mode +python ca_server.py listen ``` -## 3.2 Common usage -Once your RA registered you can simply launch your service by calling 'listen' action. This is basically what the services is doing. -```bash -./ca_server.py listen +The server will start listening on: + +- `tcp://*:5000` — CA operations +- `tcp://*:5001` — RA registration + +## Configuration + +The CA server uses a YAML configuration file. On first run, it creates a default configuration. Key configuration options include: + +```yaml +ca: + name: "uPKI Root CA" + validity_days: 3650 + key_type: "RSA" + key_size: 4096 + hash_algorithm: "sha256" + +server: + host: "0.0.0.0" + ca_port: 5000 + ra_port: 5001 + +storage: + type: "file" + path: "./data" ``` -## 4. Advanced usage -If you know what you are doing, some more advanced options allows you to setup a specific CA/RA couple. +## Usage Examples + +### Initialize a New CA -### 4.1 Change default directory -If you want to change the default directory path ($HOME/.upki) for logs, config and storage, please use the 'path' flag ```bash -./ca_server.py --path /my/new/directory/ +python ca_server.py init --config custom_config.yaml ``` -If you want to change only log directory you can use the 'log' flag. +### Start the Server + ```bash -./ca_server.py --log /my/new/log/directory/ +# Start with default settings +python ca_server.py listen + +# Start on specific host +python ca_server.py listen --host 127.0.0.1 ``` -### 4.2 Import existing CA keychain -If you already have a CA private key and certificate you can import them, by putting PEM encoded: - . Private Key (.key file) - . optionnal Certificate Request (.csr file) - . Public Certificate (.crt file) -All in same directory and call -```bash -./ca_server.py init --ca /my/ca/files/ +### ZMQ Client Operations + +Connect to the CA server using ZMQ to perform operations: + +```python +import zmq + +# CA operations port (5000) +context = zmq.Context() +ca_socket = context.socket(zmq.REQ) +ca_socket.connect("tcp://localhost:5000") + +# RA registration port (5001) +ra_socket = context.socket(zmq.REQ) +ra_socket.connect("tcp://localhost:5001") ``` -### 4.3 Listening IP:Port -In order to deploy for more serious purpose than just testing, you'll probably ended up with a different server for your RA.
