Convert-Base64 PowerShell Script

Overview

This PowerShell script provides a function Convert-Base64 that takes a file path as input and performs either Base64 encoding or decoding on its content. If the file is already in Base64 format, it decodes it; otherwise, it encodes the file content to Base64 format.

Features

• Automatically detect whether a file is Base64 encoded
• Encode to Base64 if the file is not already Base64 encoded
• Decode from Base64 if the file is Base64 encoded

Prerequisites

• PowerShell 5.1 or higher

Usage

1. Open PowerShell terminal.
2. Navigate to the directory where the script is saved or import it.
3. Run the function Convert-Base64.

PS C:\> .\path-to-script.ps1
PS C:\> Convert-Base64

4. You'll be prompted to enter the file path:

Enter the path of the file you want to convert: C:\path\to\your\file.txt

The script will automatically determine if the file is Base64 encoded and will encode or decode accordingly.

Error Handling

• If the file does not exist, the script will output "File does not exist. Exiting..." and terminate.
