Cryptography
Cryptography, or cryptology is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages.

In developing a secure client-server model, we implement the Advanced Encryption Standard (AES) and a hashing algorithm from scratch. The AES implementation includes key expansion, key-mixing operations, and secure modes like Cipher Block Chaining (CBC). For hashing, we choose SHA-256 and ensure its resistant to common cryptographic attacks.
