cryptography

A minimalist stack-based programming language designed as a flexible framework for implementing and exploring algorithms. Its syntax and semantics are inspired by PostScript and Forth, offering 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.

C++17 header only library for common cross-platform networking, sockets, ssl, threading, new language features, crypto, and serial i/o support.

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

scared is a side-channel analysis framework.

A minimalist implementation of AES algorithms in C

The Virtual Security Module (VSM) is a Rust-based cryptographic system designed to manage secure key generation, certificate authorities, and authentication workflows. It provides a hierarchical Signing Authority (SA) structure with deterministic root and sub-CA keys, enabling mTLS authentication and WebAuthn passkey support. Built for resilience and security, VSM ensures reproducible key derivation from a seed phrase while offering flexible certificate management for user authentication and authorization.

estraces is a Python library to manipulate side-channel trace sets. It aims at giving a clear and uniform API to handle traces samples and metadata for various persistency and file formats.

JetstreamDB is a universal database backend by Schmied Enterprises LLC. It is a component to build into solutions for management consulting customers.

It has been running in production since April 2023. It is an open-source component, any use requires a paid audit. The logo was inspired by the tea clipper.
