The Illustrated TLS 1.3 Connection: Every byte explained

The Illustrated QUIC Connection: Every byte explained

A simple tool to securely communicate with others.

📜 End-to-end encrypted messaging on Algorand with hybrid ECDH + PSK ratcheting

Quinto tool della serie EntropyPipeline: trasforma entropia verificata in materiale crittografico utilizzabile tramite HKDF-SHA256, con rigorosa separazione di dominio per AES, HMAC, X25519, Ed25519 e RSA.

A self-contained web app demonstrating secure, end-to-end encryption for Ethereum wallets using X25519 keypairs, on-chain public-key registration, and off-chain message envelopes.

X25519-only TLS ends for GHE

End-to-end encrypted, serverless peer-to-peer messenger that runs entirely in the browser. Deniable X25519 handshake, double ratchet, out-of-band safety numbers. No server, no account.

Hybrid classical + post-quantum key exchange for IoT: real benchmarks of ML-KEM, ML-DSA, Falcon, SPHINCS+ vs X25519/ECDH, side-channel timing analysis, and a novel adaptive hybrid ratchet protocol.
