File Integrity Checker

A PowerShell script for monitoring file integrity by calculating and comparing file hashes. The script allows you to either collect a new baseline of file hashes or monitor existing files against a previously saved baseline to detect changes or deletions.

Features

• Collect Baseline: Generate a hash baseline of all files in a specified directory and save it to a file.
• Monitor Files: Continuously monitor files in the specified directory and alert if any file is created, modified, or deleted compared to the baseline.

Requirements

• PowerShell 5.1 or later
• Access to the directory you want to monitor

Setup

1. Clone the Repository:

   git clone https://github.com/yourusername/file-integrity-checker.git
   cd file-integrity-checker
   

2. Create Directory:

   Ensure a Files directory exists in the same location as the script

   New-Item -Path "$PSScriptRoot\Files" -ItemType Directory
   
   

Usage

1. Collect a New Baseline:

   Run the script and select option 'A' to collect a new baseline of file hashes.

2. Monitor Files:

   Run the script and select option 'B' to start monitoring files against the existing baseline

Troubleshooting

• Directory Not Found: Ensure the 'F'iles directory exists at the specified path.
• Permissions Issues: Ensure you have the necessary permissions to read files and create/remove files in the script directory.
