Incorporate more advanced or efficient data structures for handling large files
Optimize or parallelize encryption tasks using concurrency (for example, multithreading or multiprocessing using Python)
Add elliptic-curve cryptography (ECC) or Argon2 for hashing as an alternative to SHA-256
Evaluate computational complexity and compare different modes of encryption (CBC, GCM, etc.)
This modular approach showcases I will be enhancing Zencrypt to handle large files more efficiently, optionally leverage advanced cryptographic algorithms, and even use concurrency. The flow also leaves open the possibility of using more sophisticated data structures (for example, using queues, thread pools, or even Merkle trees for batch hashing) to optimize the app even further.
