Loading the in-browser cryptography demo. The post-quantum, homomorphic-encryption and secure-multiparty-computation code all run in this tab, so the first load fetches them once.
This demo computes entirely in your browser — post-quantum key exchange, CKKS homomorphic encryption and garbled-circuit MPC — so it needs JavaScript and WebAssembly. There is no server-side fallback, because there is no server-side compute.
