PiedPiper

A Data Compression and Data Encryption Organization

About

This is a project extension for the Algorithms course by team Pied Piper. It's main aim is :

1. Exploring the various concepts and implementing bottom up , various compression and encryption Algorithms.
2. Explore concepts of Cellular Automaton and implement self-designed encryption engine using elementary cellular Automaton.
3. Understand concepts like Cellular Automaton Transform, etc. that have huge potential for applications in encryption and lossy data compression.
4. Implement Image compression algorithms like K-means, JPEG, PBIC.
5. Implement from scratch data compression and binary file compression algorithms like Huffman and Arithmetic Compression.
6. Produce analysis papers for the concepts learnt and implemented.

Solana Integration

The web hub and interactive modules include wallet connection, live Solana RPC status, and wallet-signed Memo proofs. The shared integration lives in shared/solana-integration.js and defaults to devnet.

encrypted-chat/index.html adds a browser-only encrypted room chat that derives AES-128-GCM keys from a room name and shared secret, then writes ciphertext envelopes to the Solana Memo program.

See SOLANA_INTEGRATION.md for the page map, supported clusters, proof behavior, and security notes.

Universal Computer Runtime

GameOfLife/index.html is the Solana-backed universal-computer surface. The Conway automaton runs in the browser, while shared/solana-integration.js records wallet-signed Solana Memo proofs for selected generations. The companion notes live in UNIVERSAL_COMPUTER.md.

Native components are buildable locally:

npm test
make -C PP_HASH test
make -C PP_SSH

The browser demos are static pages. npm test verifies local HTML references and CDN dependency pins; npm start serves the hub on port 4173 for localhost-only browser APIs such as Web Crypto.
