Cipherbox is what I consider to be a cryptographic swiss knife. It utilizes six encryption algorithms, and it's also a vault that's locked with four RFID cards, your username, and password.

Consumer-side integrity verification for Ruby gems

Immutable checkpoint storage for ML training pipelines. Kernel-level protection, anomaly detection, score-gated rollback, and self-healing recovery. Built in Rust.

Core backend service for the Integrity Hash FIM platform, providing file integrity verification and tamper detection.

This is a read only mirror of https://gitlab.com/nirs/blkhash

Standalone open-source verifier for MBX v2 — AiBenchLab's tamper-evident benchmark export format. Three dependencies, zero network access, reproduces the SHA-256 content hash to confirm an .mbx.json file hasn't been altered since export.

A small text encryption and obfuscation program which turns any text into an invisible encrypted blob, born from my previous non-github projects where I was messing around with stacking encryption

A secure, full-stack digital evidence chain-of-custody logging system. Features dynamic SHA-256 integrity verification, secure analyst authentication, and PostgreSQL database triggers to enforce total audit trail immutability against insider tampering.

This code enables you to encrypt your data using a combination of AES and Blowfish encryption algorithms in CBC mode.

Blockchain-anchored platform designed to provide provenance for scientific research data. It address the reproductiability crises that once the data is collected it cannot be altered, deleted or falsified without detection

Provide a Secure Software Adaptable Logger solution not currently available with existing logging tools, utilities or systems. Log message protected from development through deployment.

Decentralized, poisoning-resistant distribution for ML models and datasets. Publishers sign once, untrusted mirrors distribute, and any consumer verifies the exact signed bytes with full provenance.

Security-first AI artifact registry — digest-based storage, policy-gated promotion, signed provenance, and reproducible trust metadata for local models, adapters, and tokenizers

miniGit is a simplified Git-like version control system built in C++ that implements core Git workflows (commits, branching, staging, object storage) while using Merkle Trees for fast change detection and repository integrity verification.

Beyond manual assertions: HashSpec is a behavioral integrity framework for .NET that treats application state as a deterministic snapshot, providing a regression safety net for your application.

數位證據複製與歸檔工具 (FEIT) - A Windows-based forensic evidence ingestion tool. Resolves long path limits, preserves metadata/timestamps via Robocopy, and validates integrity with dual-stage SHA-256 hashes.

A lightweight, file-based database engine for Python with SHA-256 hashing, ACID transactions, and zero external dependencies.

A content-authenticity verifier — not a deepfake detector. Proves origin instead of racing detection. The provenance layer of the Mirror Stack.

Encrypt text using stacked AES-256 GCM and PGP encryption with obfuscation and integrity checks.
