newspeak

rust

End-to-end encrypted chat in Rust implementing Signal's Post-Quantum Extended Diffie-Hellman and Double Ratchet. Built with tonic for gRPC, SQLite for storage, dalek primitives, and a ratatui terminal UI.

c25519

c

Side-channel attack resistant Ed25519 implementation in C that also includes SHA-512. It focuses on practical performance while passing a broad set of test vectors.

psync

go

Command-line sync tool for untrusted providers that encrypts files and hides metadata such as exact file count and file sizes. Uses ChaCha20-Poly1305 for encryption and Argon2id for key derivation.

secp256k1

c

secp256k1 signing and verification implementation with Jacobian coordinates and Montgomery representation to reduce expensive operations. Includes deterministic RFC6979 nonces.

hkdf

c

Self-contained header-only HKDF implementation in C with SHA-256 and HMAC primitives included.

pqxdh

go

Go library for Post-Quantum Extended Diffie-Hellman and XEdDSA. Extends X3DH with ML-KEM to provide stronger resistance against future quantum adversaries.

merkle

goc

Merkle tree implementations in Go and C using SHA-256, including generation and verification of inclusion proofs.

schnorr

python

Schnorr signatures implemented over secp256k1 curve in 100 lines of Python. Serves as an educational implementation without dependencies (related to math).

gocry

go

Proof-of-concept ransomware implementation for educational and security research purposes.

kukka

rust

Small and fast parser combinator library in Rust that uses static dispatch to avoid trait-object overhead. It's mature enough to write parsers for JSON and CSV in a few lines..

ampl

zig

Concurrent programming language written in Zig that explores Erlang-inspired ideas with a less functional style.

mc

go

A simplistic C compiler written in Go with lexical analysis, parsing, IR generation, and x64 assembly output. Stopped working on this after getting a macbook.

haystack

go

Distributed file system inspired by Facebook's Haystack architecture. Uses a Raft-based directory cluster to map files to append-only volumes and coordinates replication across store servers.

distsql

go

Distributed consensus layer built on top of SQLite for coordinating state across nodes.

levelsql

go

Minimal SQL implementation that stores relational data as key-value pairs on LevelDB.

dot

go

A tiny easy-to-use dotfile manager built using in Go in a few hundred lines.

hashvis

c

Small command line utility that generates unique ASCII art based on file contents written in C.
