CryptoLyzer is a fast, flexible, and comprehensive server cryptographic protocol (TLS, SSL, SSH, DNSSEC) and related setting (HTTP headers, DNS records) analyzer and fingerprint (JA3, HASSH tag) generator with Python API and CLI.

Cryptographic protocol and security-related protocol piece parser.

Free repository of cryptography-related data.

A sponge-based secure hash function that uses AES-256 as its internal PRF.

Proofora is a blockchain-based identity and authentication protocol designed to securely verify individuals and their authorized devices through biometric liveness verification, cryptographic identity commitments, challenge-response authentication, and blockchain-backed credentials. It prioritizes privacy by keeping sensitive biometric data under user-controlled custody while providing verifiable proof of identity and trusted device connections. https://roxanneardary.com/proofora/

A package that handles key pair generation and encryption / decryption of secrets using keys

QUIC-native TLS 1.3 implementation in Zig. RFC 8446/9001 compliant with zero external dependencies.

Zig Hardware Security Module library for PIV, CAC, and YubiKey tokens via PC/SC. Supports certificates, PIN management, signing, and decryption.

Leonardus is an open source project. It is a minimalist, stack-based programming system designed as a flexible framework for implementing and exploring algorithms. The syntax and semantics of its scripting language, LeoScript, are inspired by PostScript and Forth. It is extended with a prototype-based, object-oriented paradigm, has seamless integration into JupyterLab and Docker, and provides a concise and expressive environment for learning and experimentation.

The project name is a nod to Leonardus Pisanus, who was named and became known as Fibonacci.

Consult the project's GitLab Pages for documentation.

Umbrix is a commercial-grade, open-source VPN designed for full network obfuscation, multi-node chaining, and AI-assisted adaptive privacy. It masks everything from IP and location to device telemetry, provides cross-platform support, and includes advanced features like multi-hop routing, stealth traffic transforms, decentralized node management, and post-quantum-ready cryptography. Built for maximum anonymity, Umbrix ensures your online activity remains invisible, secure, and untraceable. https://roxanneardary.com/umbrix/

A minimalist implementation of AES algorithms in C

fastCrypter is a powerful Python library that combines advanced compression and encryption techniques with native C/C++ acceleration for maximum performance. It provides a comprehensive suite of tools for secure data handling, from simple file encryption to complex custom encoding schemes.

BalanceSeal is an AGPL 3.0+ cryptographic audit module for cryptocurrency exchanges and digital wallets that generates a verifiable, time-frozen snapshot of all user assets at the moment an account is terminated. It aggregates on-chain and off-chain balances, reconciles holdings across systems, locks market pricing at the termination timestamp, and produces tamper-evident reports for compliance, auditing, and transparency. https://roxanneardary.com/balanceseal/

SelfRoot is an open-source deterministic identity infrastructure project that replaces passwords and centralized identity systems with cryptographic authentication derived from live human presence. It processes biometrics locally, converts them into non-reversible templates, and uses them to unlock hardware-bound cryptographic keys for secure challenge–response authentication, without storing or transmitting biometric data. https://roxanneardary.com/selfroot/

A lightweight password manager written in C.

Vault is a personal project built to explore low-level programming concepts through the development of a secure password manager. The goal is to understand how storage, memory management, file handling, and cryptographic mechanisms work by implementing the core components from scratch.

VeritasVote is an open-source, tamper-evident in-person voting machine. Fully auditable, cryptographically verifiable, and backed by paper ballots, it provides transparent and secure elections. Hardware and software are fully open for inspection, ensuring every vote can be trusted. https://roxanneardary.com/veritasvote/

These projects form an open-source suite of AI infrastructure tools built for modularity, security, and self-hosted deployment, allowing users to maintain full ownership and control of their systems and data. They deliver interoperable AI functions including automation, data retrieval, encryption, and identity management that can be applied across many different industries. https://roxanneardary.com/ai-infrastructure/

Blockchain specifications define an institutional blockchain system built on distributed custody using Multi-Party Computation (MPC), where no single entity can access or control private keys. All transactions are governed through policy engines, role-based permissions, and full audit logging instead of centralized custody. It supports tokenization and multi-chain interoperability for real-world assets like real estate and financial instruments, with deployment across on-prem, sovereign cloud, and hybrid environments. The result is a secure, auditable infrastructure for programmable assets with built-in compliance and institutional control. https://roxanneardary.com/blockchain/

FluxCore Mobility is a modular, edge-first vehicle intelligence system designed to keep all critical AI processing local to the vehicle while enforcing strict, cryptographically validated user consent for any external data sharing. Built under the AGPL 3.0+ license, it prioritizes privacy, transparency, and deterministic safety by separating core driving logic from optional cloud and experimental features. Its architecture ensures that no data leaves the system without explicit, time-bound approval, making it a framework for consent-bound automotive intelligence rather than continuous background connectivity. https://roxanneardary.com/fluxcore-mobility/
