lupaxa-certtool

A clean, modern, fully-typed Python CLI and library for generating self-signed X.509 certificates, certificate signing requests (CSRs), and private keys.

Built for automation, reproducibility, and bulk-generation workflows used by The Lupaxa Project.

Features

Generate self-signed certificates, private keys, and CSRs
Generate from:
- JSON config file
- Directory of config files (bulk mode)
- Pure command-line flags
Output:
- To stdout
- Or into an output directory, with one folder per certificate
Supports:
- RSA key generation
- SHA-256 / SHA-384 / SHA-512 digests
- Validity period configuration
- Optional private key encryption with passphrase
- Subject Alternative Names (SANs) via JSON or CLI
Includes:
- --generate-example to produce a full example JSON config
- --inspect-cert to analyze existing PEM certificates
- --validate-config to validate config files before use
Fully typed, linted, formatted, and tested
MkDocs documentation included

Installation

From PyPI

pip install lupaxa-certtool

From source (development mode)

pip install -e ".[dev]"

Usage

Basic self-signed certificate from CLI

certtool \
  --countryName UK \
  --stateOrProvinceName Somerset \
  --localityName Glastonbury \
  --organizationName "Lupaxa Project" \
  --commonName "dev.internal"

Using JSON Configuration

Generate an example config

certtool --generate-example --example-file dev-internal-cert.json

Use a JSON config file

certtool --config dev-internal-cert.json

Use a directory of configs (bulk mode)

certtool --config-dir configs/

Output Directory Structure

If you pass:

certtool --config-dir configs/ --output-dir output/

You get:

output/
├── dev.internal/
│   ├── cert.pem
│   ├── csr.pem
│   └── key.pem
└── api.internal/
    ├── cert.pem
    ├── csr.pem
    └── key.pem

Each certificate gets its own folder to prevent overwriting.

Private Key Encryption

JSON

{
  "passphrase": "your-secret-here"
}

CLI (overrides JSON)

certtool --config dev-internal-cert.json --passphrase "some-secret"

Inspect a Certificate

certtool --inspect-cert output/dev.interal/cert.pem
