MediaCrypt

MediaCrypt is a Python-based tool that lets you hide text inside media files and pull it back out with a key.

Features

• Hides text in media files (like .wav, .mp3, etc.).
• Creates a key file for decryption.

Requirements

• Python 3.x (for source code, when it’s out)
• Nothing extra needed for the .exe files

Installation

The source code isn’t up yet but will be on GitHub later:

git clone https://github.com/ZailoxTT/MediaCrypt.git

For now, just grab the encrypt.exe and decrypt.exe files to use the tool.

Usage

Encryption

1. Run encrypt.exe:

   encrypt.exe

2. Enter these when asked:
   • Text to encrypt: The message you want to hide.
   • Key file: Where to save the key (e.g., key.txt).
   • Original media file: The media file to use (e.g., song.wav).
3. The text gets added to the media file, and the key is saved.

Decryption

1. Run decrypt.exe:

   decrypt.exe

2. Enter these when asked:
   • Media file: The media file with hidden text.
   • Key file: The key file from encryption.
   • Save decrypted to: Where to save the text (e.g., output.txt).
3. The original text gets pulled out and saved.

How It Works

• Encryption: The text is hidden in the media file, and a key file is made to unlock it later.
• Decryption: The tool reads the hidden text from the file and uses the key to reveal it.

Limitations

• Only letters (A–Z, a–z) get hidden; other characters stay as-is.
• Big texts might make the file size obviously larger.
• Works best with files like .wav that don’t mind extra data at the end.

Example

Encryption

Text to encrypt: Hello, World!
Key file: key.txt
Original media file: song.wav

Output: Text hidden in song.wav, key saved in key.txt.

Decryption

Media file: song.wav
Key file: key.txt
Save decrypted to: output.txt

Output: Hello, World! saved to output.txt.
