Enhance Image Encryption with Key-Based Decryption.

[Rupak09]

Description:
Implement a key-based encryption and decryption mechanism to enhance the security and control over the image encryption algorithm. The goal is to generate a unique cryptographic key during the encryption process, which will be essential for decrypting the encoded image. This key should be securely connected to the encrypted image, establishing a direct link between the encoded data and the decryption process.

Objectives:

Key Generation: Develop a method for generating a cryptographic key during the image encryption process. The key should be sufficiently random and secure to prevent unauthorized access to the decrypted content.

Key Integration: Establish a secure association between the generated key and the encrypted image. This linkage ensures that the decryption process relies on the presence and accuracy of the associated key.

Decryption Dependency: Modify the decryption process to incorporate the generated key as a necessary component. The key should be an indispensable factor for successfully decrypting the image and reconstructing the original content.

Benefits:

Enhanced Security: Introducing a cryptographic key adds an extra layer of security, making it more challenging for unauthorized parties to access or manipulate the decrypted image.

Controlled Access: The key-based approach allows for controlled access to the decryption process, ensuring that only those with the correct key can decipher the encoded image.

Versatility: This enhancement facilitates the implementation of various encryption scenarios, supporting different use cases that require tailored security measures.

Note to Contributors:
Contributors are encouraged to explore established cryptographic principles and best practices when implementing the key generation and integration mechanisms. Consider the potential impact on performance and ensure that the key-based decryption process is seamless and user-friendly. Documentation should be updated to guide users on the proper usage of keys in the encryption and decryption workflows.
