SecureFileEncryptor

SecureFileEncryptor is a PowerShell tool for securely encrypting and decrypting text, files, and folders using password-protected SHA-256 hashing. The tool provides a simple interactive menu, allowing users to perform encryption and decryption operations on individual texts, files, or entire directories.

Features

• Text Encryption/Decryption: Encrypts plain text to a secure, hashed format, and decrypts it back to the original text.
• File Encryption/Decryption: Encrypts text content within files and saves it in the same file securely.
• Folder Encryption/Decryption: Processes all files within a folder for batch encryption or decryption.
• SHA-256 Password Hashing: Uses a SHA-256 hash of your password as the key, adding an extra layer of security.

Prerequisites

• PowerShell: Ensure PowerShell is installed on your system (version 5.1 or later recommended).

Usage

1. Download and open the script in PowerShell.
2. Run the script: .\SecureFileEncryptor.ps1
3. Choose an option from the menu:
   • 1: Encrypt Text
   • 2: Decrypt Text
   • 3: Encrypt File
   • 4: Decrypt File
   • 5: Process Folder (Encrypt or Decrypt all files in a folder)
   • 6: Exit the application

Example Usage

.\SecureFileEncryptor.ps1

Encrypting a Text String

1. Select 1 to Encrypt Text.
2. Enter a password.
3. Input the text you want to encrypt.
4. The tool displays the encrypted text.

Decrypting a File

1. Select 4 to Decrypt a File.
2. Enter the same password used for encryption.
3. Provide the path to the encrypted file.
4. The decrypted content will replace the encrypted content in the file.

Security Notes

• Password Matching: Ensure you use the same password for encryption and decryption.
• Data Security: Encrypted files and text should be handled carefully, as they will be overwritten in place.
