Alpha Chat — Encrypted Messaging
A secure messaging app exploring classical and modern cryptography (Caesar, Vigenère and stronger ciphers) to keep conversations private.
Overview
Alpha Chat is an applied-cryptography project exploring how to keep messaging private. Across successive prototypes (a Telegram-style chat plus standalone tools), it implements classical ciphers (Caesar and Vigenère) alongside stronger techniques, letting users encrypt and decrypt messages and understand the trade-offs of each scheme. A hands-on study of security and cryptography fundamentals.
Outcomes
- Classical and modern ciphers implemented and integrated into working chat prototypes
Key Features
- Caesar and Vigenère cipher implementations
- Message encryption & decryption tools
- Iterative Telegram-style chat prototypes
- Hands-on demonstration of cryptography fundamentals
- Python and web (HTML/JS) implementations
