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. +uPKI is a lightweight, modern PKI management system that provides a simple yet powerful way to manage certificates, keys, and public key infrastructure. It supports both file-based and MongoDB storage backends, with ZeroMQ-based communication for Registration Authority (RA) interactions. -If needed you can still check options using -```bash -./ca_server.py --help -``` +## Project Structure -## 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 -```bash -./ca_server.py register ``` - -## 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 +📂 upkica/ +├── 📂 ca/ +│ ├── authority.py +│ ├── certRequest.py +│ ├── privateKey.py +│ └── publicCert.py +├── 📂 connectors/ +│ ├── listener.py +│ ├── zmqListener.py +│ └── zmqRegister.py +├── 📂 core/ +│ ├── common.py +│ ├── options.py +│ ├── upkiError.py +│ └── upkiLogger.py +├── 📂 data/ +│ ├── admin.yml +│ ├── ca.yml +│ ├── ra.yml +│ ├── server.yml +│ └── user.yml +├── 📂 storage/ +│ ├── abstractStorage.py +│ ├── fileStorage.py +│ └── mongoStorage.py +└── 📂 utils/ + ├── admins.py + ├── config.py + └── profiles.py ``` -## 4.
