Can be a comma-separated list if multiple types are needed. - `--overwrite`: A boolean flag indicating whether existing certificates should be overwritten. 2. **Configuration File Support**: - Allow users to specify parameters via an external JSON configuration file. - If both command-line arguments and configuration file are provided, command-line arguments should take precedence. 3. **Certificate Generation Logic**: - Implement `generate_certs(cert_type="all", overwrite=False)` function which generates certificates based on given parameters. - Support at least two types of certificates: "self-signed" and "CA-signed". - Ensure secure handling of file operations when generating certificates. 4. **Error Handling**: - Provide meaningful error messages for invalid inputs or failed operations. 5. **Logging**: - Integrate logging functionality using Python’s `logging` module. 6. **Concurrency Handling** (Optional but recommended): - Ensure that multiple instances of certificate generation can run concurrently without conflicts. #### Starter Code: Refer to [SNIPPET] for basic structure. ### Solution python import argparse import json import logging import os # Configure logging logging.basicConfig(level=logging.INFO) logger = logging.getLogger(__name__) def generate_certs(cert_type="all", overwrite=False): if cert_type == "all": cert_types = ["self-signed", "CA-signed"] else: cert_types = cert_type.split(',') for cert in cert_types: if cert == "self-signed": logger.info("Generating self-signed certificate...") # Add logic here... if not overwrite and os.path.exists(f"{cert}.crt"): logger.warning(f"{cert}.crt already exists; skipping due to overwrite=False") continue # Dummy implementation; replace with actual logic with open(f"{cert}.crt", "w") as f: f.write("Dummy self-signed certificate") logger.info(f"{cert}.crt generated successfully") elif cert == "CA-signed": logger.info("Generating CA-signed certificate...") # Add logic here... if not overwrite and os.path.exists(f"{cert}.crt"): logger.warning(f"{cert}.crt already exists; skipping due to overwrite=False") continue # Dummy implementation; replace with actual logic with open(f"{cert}.crt", "w") as f: f.write("Dummy CA-signed certificate") logger.info(f"{cert}.crt generated successfully") def parse_args(): parser = argparse.ArgumentParser(description="Generate SSL/TLS certificates.") parser.add_argument("--cert_type", type=str, default="all", help="Type(s) of certificates to generate (comma-separated). Options: self-signed, CA-signed.") parser.add_argument("--overwrite", action='store_true', help="Overwrite existing certificates.") parser.add_argument("--config_file", type=str, help="Path to configuration JSON file.") return parser.parse_args() def load_config(config_file): try: with open(config_file, 'r') as f: config = json.load(f) return config['cert_type'], config['overwrite'] except Exception as e: logger.error(f"Failed to load configuration file {config_file}: {e}") return None, None def main(): args = parse_args() config_cert_type = None config_overwrite = False if args.config_file: config_cert_type, config_overwrite = load_config(args.config_file) if config_cert_type is not None: args.cert_type = config_cert_type if config_overwrite is not None: args.overwrite = config_overwrite generate_certs(args.cert_type, args.overwrite) if __name__ == "__main__": main() ### Follow-up exercise 1. Extend functionality so that it supports additional certificate attributes such as validity period (in days), key size (in bits), etc., which can be specified via command-line arguments or configuration file. 2. Modify `generate_certs` function so that it validates generated certificates using an external tool like OpenSSL after creation. 3. Implement multi-threading support so that multiple types of certificates can be generated concurrently without interfering with each other's file operations. 4. What if we need support for revoking certificates? Extend your solution by adding functionality to revoke existing certificates based on certain conditions (e.g., expiration date). ### Solution python import argparse import json import logging import os import threading # Configure logging logging.basicConfig(level=logging.INFO) logger = logging.getLogger(__name__) def generate_certs(cert_type="all", overwrite=False): def generate_self_signed(): logger.info("Generating self-signed certificate...") if not overwrite and os.path.exists("self_signed.crt"): logger.warning("self_signed.crt already exists; skipping due to overwrite=False") return with open("self_signed.crt", "w") as f: f.write("Dummy self-signed certificate") logger.info("self_signed.crt generated successfully") def generate_ca_signed(): logger.info("Generating CA-signed certificate...") if not overwrite and os.path.exists("ca_signed.crt"): logger.warning("ca_signed.crt already exists; skipping due to overwrite=False") return with open("ca_signed.crt", "w") as f: f.write("Dummy CA-signed certificate") logger.info("ca_signed.crt generated successfully") threads = [] if cert_type == "all": cert_types = ["self_signed", "ca_signed"] else: cert_types = cert_type.split(',') for cert in cert_types: if cert == "self_signed": thread = threading.Thread(target=generate_self_signed) threads.append(thread) thread.start() elif cert == "ca_signed": thread = threading.Thread(target=generate_ca_signed) threads.append(thread) thread.start() for thread in threads: thread.join() def parse_args(): parser.add_argument("--validity_period", type=int, help="Validity period for certificates in days.") parser.add_argument("--key_size", type=int, help="Key size for certificates in bits.") return
