Decentralized End-to-End Encrypted Messenger

Modern cryptography primitives implemented in Scratch, via Boiga

a high-level async cryptographic anonymity library to scale, simplify, & automate privacy best practices for secure data & identity processing, communication, & storage.

A python implementation for Noise Protocol Framework

Elliptic Curves for Security (RFC 7748) : x25519 and x448 implementation in Python

End-to-end encryption for HTTP APIs using RFC 9180 HPKE. Drop-in middleware for FastAPI, aiohttp, and httpx.

Encryption/backup utility

Hybrid classical + post-quantum cryptographic toolkit. Combines X25519/Ed25519 with ML-KEM-768/ML-DSA-65 (NIST FIPS 203/204). Security holds if either primitive survives.

Text people using only terminal.

A fully decentralized, cryptographically secure P2P messaging system with zero trust assumptions, no central servers, and strong identity-based communication.

Secure Digital Agent Protocol — HTTPS for AI agent communication. Cryptographic identity, mutual authentication, encrypted payloads, trust delegation, and audit trails for multi-provider agent ecosystems. Works with A2A, MCP, and any agent-to-agent protocol.

client-server chatroom using ecdsa/x25519/sha256 algorithms (CODE) [ PYTHON ]

Secure Optical Air-Gap File Transfer via QR-Code GIFs Hiss secrets into yarn balls 😼 — cat-meme QR GIFs built for camera loss (fountain codes) and fail-closed crypto.

MCP server for post-quantum cryptography (ML-KEM, ML-DSA, SLH-DSA) with hybrid X25519+ML-KEM-768 key exchange. Research/prototyping tooling using liboqs.

Simple end-to-end encrypted messenger using Python and AES-CTR (client & server like netcat)

A X25519/AES secured and threaded python messenger

Secure messaging core using X25519, Ed25519, HKDF, and AEAD for encrypted communication, with versioned envelopes, replay protection, and encrypted local storage. Hybrid-ready, testable, and built as a cryptographic engine rather than a full chat app.

🔐 Python implementation of the AlgoChat protocol for encrypted messaging on Algorand

PyCryptX - an X25519 + Ed25519 + ChaCha20 + BLAKE2b based public key encryption program in Python. This is an unaudited hobby project!

IX-Operator is a secure operator platform for autonomous agents, combining a Rust cryptographic core with a Python runtime for authenticated sessions, encrypted messaging, and auditable orchestration. Built for clarity, testability, self-hosted deployment, and serious use for real teams.
