# Random_Message

## Overview

The `Random_Message` in `MrLou_modules` is a Python package that provides a collection of random messages, including fun facts and jokes. 
This package is designed to be easy to use and integrate into your Python projects to add a touch of randomness and fun.
I'm using it in script that takes a bit long to complete so printing out those messages keep me awake

## Usage
To use the package in your Python script, follow these steps:

1. Import the necessary function:

```
from MrLou_modules.Random_Message.random_message import get_random_message
```

2. Get a random message:

```
message = get_random_message()
print(message)
```

The `get_random_message` function will alternately return a joke or a fun fact each time it is called.

## Example
Here’s a simple example of how to use `MrLou_modules`:

```
from MrLou_modules.Random_Message.random_message import get_random_message

# Print a random message
print(get_random_message())
```

### Functions
- `get_random_message()`: Returns a random message, alternating between jokes and fun facts.

### Modules
- `fun_facts.py`: Contains a list of interesting and random fun facts. Example facts include:

- `jokes.py`: Contains a list of light-hearted programming jokes. Example jokes include:

- `random_message.py`: Provides the get_random_message function that alternates between fun facts and jokes.

# Cyberark

The `cyberark_api` is a collection of one API for now :-)
The `variables.py` contain all the configuration values such as URIs, certificate paths, and usernames
the `cyberark_api.py` has one class with a function `get_credentials` that you can use to pull credential stored in Cyberark

## Example
Here’s a simple example of how to use `MrLou_modules`:

create a variables.py with your variables by adjusting the <>:

for example, 
AppID = "<AppID>" to AppID = "MyAppIDexample"
ca_cert = r'C:\path\to\Trusted_Root_Certificates.pem' to ca_cert = r'C:\cert\cyberark\Trusted_Root_Certificates.pem'

```
# variables.py

# CyberArk API configurations

URI = "https://<IIS_Server_Ip>/AIMWebService/api/Accounts"
AppID = "<AppID>"
Safe = "<Safe>"
Folder = "<Folder>"
Username = "<Username>"
Object = f"<Object>{Username}"


ca_cert = r'C:\path\to\Trusted_Root_Certificates.pem'
client_cert = r'C:\path\to\_unencrypted_device.crt'
client_key = r'C:\path\to\_unencrypted_key.pem'
```

The main script is 
```
import variables
from MrLou_modules.Cyberark.cyberark_api import CyberArkAPI

cyberark_api = CyberArkAPI(variables)
credentials = cyberark_api.get_credentials()

if credentials:
    print(f"Username: {credentials['Username']}")
    print(f"Password: {credentials['Password']}")
    print(f"Password Change In Process: {credentials['PasswordChangeInProcess']}")

```

# Certificate_Utils

This guide explains how to use the cert_utils.py module, which provides tools for working with certificates and private/public keys. It includes functions to extract certificate details, decrypt private keys, verify certificates, and more.

## Functions Overview

1. extract_common_name(subject)
   - Extracts the Common Name (CN) from a certificate subject.
   - Input: A certificate subject (x509.Name object).
   - Output: The Common Name (CN) as a string, or None if not found.


2. extract_san_extension(certificate)
   - Extracts the Subject Alternative Names (SAN) from a certificate.
   - Input: A certificate (x509.Certificate object).
   - Output: A list of SAN names as strings or None if not available.


3. decrypt_and_save_private_key(file_path, passphrase, output_path)
   - Decrypts an encrypted private key and saves it as an unencrypted PEM file.
   - Input:
     - file_path: Path to the encrypted private key file.
     - passphrase: The passphrase to decrypt the key.
     - output_path: Path to save the unencrypted private key.
   - Output: Saves the unencrypted private key to the specified output path. Prints success or failure messages.


4. process_certificate(input_data, passphrase=None)
   - Reads and processes a certificate or key from a file path or a PEM-encoded string.
   - Input:
     - input_data: A file path or a PEM-encoded string.
     - passphrase: Optional passphrase to decrypt private keys.
   - Output: Depending on the content (certificate, public/private key), returns key or certificate details (e.g., validity, public key) or prints an error if invalid.


5. find_cert_and_key_files(base_path)
   - Searches the given directory (base_path) for certificate and key files.
   - Input: The base directory path to search.
   - Output: A tuple with paths to the certificate and key files.


6. process_certificate_and_key(cert_file_path, key_file_path, passphrase=None)
   - Verifies whether the private key matches the certificate.
   - Input:
     - cert_file_path: Path to the certificate file.
     - key_file_path: Path to the private key file.
     - passphrase: Optional passphrase to decrypt the private key.
   - Output: Prints whether the private key matches the certificate.


7. get_public_key_from_private_key(private_key)
   - Extracts the public key from a private key.
   - Input: A private key (cryptography key object).
   - Output: The public key associated with the private key.


8. compare_public_keys(cert_public_key, key_private_key)
   - Compares the public key from a certificate with the public key derived from a private key.
   - Input:
     - cert_public_key: Public key from the certificate.
     - key_private_key: Private key to derive the public key from.
   - Output: Returns True if the public keys match, otherwise False.
