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.

discord economy bot with (sub-optimal) blockchain implementation. inspired from rithmian's video on youtube about a blockchain app with fastapi. (which was slightly misleading as his blocks had only one transaction for the video's simplicity sake, which is understandable, the format of the video could not allow for a deeper implementation)

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.
