guides
Long-form walkthroughs of what's hosted here — how each demo is built, what's on the wire, what's a real risk and what's just an alarm. Read front-to-back or jump in. They assume you'd rather know what's happening than take our word for it.
pq-share, a guide
End-to-end encrypted file sharing where every send picks its own cipher suite. Walks through the eight keypairs each account carries, the picker and what it actually controls, the wire format, and the threat model. Built for people who'd rather know.
fhe-vote, a guide
A homomorphic voting system, walked end-to-end. Every ballot is encrypted at the source under a key nobody holds; the server tallies ciphertexts it cannot read; only the per-candidate totals are ever decrypted, by a quorum of trustees, after close. Covers the ring, the ballot format, the two proofs a ballot must carry, cast-or-audit, the Merkle bulletin board, and the seventeen-check universal verifier.
handshake race
Two TLS 1.3 handshakes side-by-side. Pick a cipher suite for each track, hit play, watch the messages travel between client and server with the byte counts ticking on every arrow. The point isn't speed — it's cost. Post-quantum KEX and signatures aren't "a little bigger." They're an order of magnitude bigger.
