Tapline.Client.Opaque

A .NET client's password sign-in to Tapline by OPAQUE (RFC 9807): the password stretched here (Argon2id), never sent, the router relaying KE1, KE2 and KE3 to the realm's OPAQUE module (Tapline.Wasm). opaque-ke 4.0.1 (ristretto255, Argon2id) as WebAssembly, run by Wasmtime: the same module the browser runs.

var opaque = OpaqueCrypto.Load();              // once: compiling the module takes a moment
var result = await client.SignInWithPasswordAsync(opaque, "north", "alice", password);

Disclaimer: opaque-ke was reviewed by NCC Group in 2021, at v0.5.0 (its fixes in v1.2.0), for WhatsApp's encrypted backups. That review does not cover opaque-ke 4.0.1, nor this package's own code, which has not been reviewed.

Tapline.Wasm

Tapline's WebAssembly, run by Wasmtime: a data provider's folds, finalizers and stale-data functions as sandboxed modules, fuel- and memory-bounded on the router; and password sign-in by OPAQUE (RFC 9807), a module of Tapline's authentication in which the password never leaves the client — on the server, and in the browser (opaque.mjs, tapline-opaque.mjs).
