This tool allows you to encrypt and decrypt images using a keyword-based encryption method. The encryption adds random noise to the image and embeds text into the noise, while the decryption restores the image using the same keyword.

• Encrypt images with a password/keyword.
• Embed custom text into the encrypted image.
• Decrypt encrypted images using the same keyword.

• Python 3.x
• OpenCV (cv2)
• NumPy
• Cryptography library (cryptography)

1. Clone or download the repository.

2. Install the required dependencies:

   pip install opencv-python numpy cryptography

3. Make sure you have an image file (e.g., .png, .jpg) to encrypt.

1. Open a terminal and navigate to the folder containing the imgCrypt.py file.
2. Run the script:

   python imgCrypt.py

• Encrypt Image:

  • Provide the path of the image to encrypt.
  • Enter a password/keyword to encrypt the image.
  • The tool will generate an encrypted image file and a noise image with embedded text.

• Decrypt Image:

  • Provide the path of the encrypted file (not the noise image).
  • Enter the same password/keyword used during encryption.
  • The tool will decrypt and save the original image.

Encrypting an Image

Enter input image path: /path/to/image.jpg
Enter encryption keyword: mysecretkey
Enter output file path (without extension): /path/to/encrypted_image
Enter text to embed in encrypted image: Any text you want

Decrypting an Image

Enter encrypted file path (without _noise.png): /path/to/encrypted_image
Enter decryption keyword: mysecretkey
Enter output image path: /path/to/decrypted_image.png

• Always remember the keyword used for encryption; it's required for decryption.
• The noise image (_noise.png) is generated for visual effect and contains embedded text.
