"""
This script authenticates to Azure, retrieves a secret from Azure Key Vault,
and uses it to get host details.
Prerequisites:
- Install the Azure SDK for Python:
pip install azure-identity azure-keyvault-secrets
- You need to have an Azure Key Vault created and the secret stored in it.
- The user or service principal running this script needs to have the "Get"
permission on the secret in the Key Vault.

# on your environment and what you are trying to achieve (e.g., connecting to
# a remote server, calling an API, etc.).

# Example (replace with your *actual* command - this is a *non-working* example):
# import subprocess
# try:
# # Use the secret_value here. For example, if you were using ssh:
# result = subprocess.run(
# ['ssh', '-o', 'StrictHostKeyChecking=no', '-i', 'your_private_key',
# f'user@{hostname}', 'your_command'],
# input=f'password\n', # Provide the password via input redirection (if needed, and if safe)
# stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True, check=True
# )
# print(result.stdout)
# except subprocess.CalledProcessError as e:
# print(f"Error running command: {e}")
# print(e.stderr)
#
# Another Example (if you were calling a REST API using the 'requests' library):
# import requests
# headers = {
# "Authorization": f"Bearer {secret_value}" # Or "Basic {secret_value}" or whatever the API requires
# }
# response = requests.get("https://your-api-endpoint", headers=headers)
# response.raise_for_status() # Raise an exception for bad status codes
# print(response.json())
#
# For this *simulation*, we'll just output the secret length and a message:
secret_length = len(secret_value)
print(f"Simulated host details retrieval using secret (length: {secret_length}).")
print(f"Secret Value (First 6 Characters): {secret_value[:6]}...")
print("Note: This is a *simulation*. You must replace this with your *actual* command.")
# End of simulation. Replace this with your real code.
