How can you decrypt or extract hidden data from a PNG file that uses LSB steganography with a password?

To decrypt, use a tool like cloacked-pixel with the command `python lsb.py extract big.png-stego.png output.txt password`. This reverses the embedding process by reading the least significant bits of the pixel data, applying the password-based decryption, and writing the hidden payload to a file. The same password used during encryption is required.
