curve25519

Browser-based key agreement for a first-time reader — one real X25519 exchange with both sides' secrets compared byte for byte, the eavesdropper's complete transcript and a guess against the real curve that will not land, and a stranger who answers in Bob's place while every check still passes. No modulus, no exponent, no discrete log.

handshakeless-vpn (Linux)

A command-line demonstration of end-to-end encrypted messaging using modern cryptographic protocols. This prototype implements X25519 key exchange and AES-GCM encryption to simulate secure messaging similar to WhatsApp.

Minimal X25519 (Curve25519) key exchange for embedded systems — pure C99, zero dependencies, zero allocations. Pairs with microcrypt.

An implementation of the X3DH Key Agreement Protocol with Docker containers

Pure-Go WireGuard client - Noise IKpsk2 handshake, ChaCha20-Poly1305 transport, userspace TUN, zero CGo. Built from the official whitepaper.

X25519 adapter for WebAssembly and JS implementations

Go code for those who like golosinas

End-to-end encrypted messaging between Claude Code instances. Curve25519 PFS, Ed25519 TOFU, replay protection.

A secure, client-side GPG/PGP key generator with a modern terminal-inspired interface. Generate cryptographic key pairs entirely in your browser with zero server-side processing for maximum security and privacy.

Curve25519 Diffie-Hellman key exchange (RFC 7748) in pure Standard ML

Python wrappers around Ed25519: high-speed high-security signatures by Daniel J. Bernstein

Encryption library used by Mail.io backend.

Elliptic curve 2-cycle realize pipeline: constructs CM-method curve pairs over p = 2^255-19 for recursive proof composition (IVC/SNARK/FCMP++). Finds polynomial roots over finite fields, converts class invariants to j-invariants, and emits short Weierstrass parameters with twist security analysis

X25519 Curve25519 performance tuning for Commodore 64 (6502 assembly)

Curve25519 Zephyr supervisor for STM32L0: derives per-boot AES/MAC keys, encrypted reset/watchdog state, dual-heartbeat SLAs, safe-mode recovery. Includes native_sim+hardware tests, release logs, provisioning overlay auto-persist tooling, a security backlog, and GitHub Actions CI to keep 8 KB Cortex-M0 nodes audit-safe.

A demo with native C implementation of X3DH Key Agreement Protocol for ESP32

Pure Rust implementation of Annihilative Keys, cryptographic key/antikey pairs bound by proof-of-work and elliptic curve point relationships.
