The encryption and decryption functions provided by the software are based on the password to change the pixel arrangement of the original image, and the decryption and encryption operations are performed in the opposite order.
The processed image file does not save any password information, and providing wrong password decryption will further disrupt the image.
Too simple passwords have the possibility of being cracked by multiple attempts.
In order to improve the encryption performance, multiple encryption methods can be adopted, and the order of encryption operations and the password must be kept in mind, otherwise the image cannot be decrypted.
