There was a problem hiding this comment.
Using wasm32-unknown-unknown because:
- we don't need 64 bit memory
- wasm32-unknown-unknown is a Tier 2 without Host Tools platform (wasm64-unknown-unknown is tier 3)
- this crate doesn’t need any assumptions about the host environment, so it’s fine to use unknown-unknown

This PR is the first part of the password component described at https://app.notion.com/p/convex-dev/Convex-Auth-v2-Passwords-38ab57ff32ab80a4b395f94378ebb958?source=copy_link. As described in the design doc, we’re going to implement Argon2id hashing using a small WebAssembly module we’re going to embed in the component. This PR adds this module, while the actual component itself will be implemented in subsequent PRs.
This module is a thin wrapper around the
argon2Rust crate. It’s maintained by the RustCrypto organization and considered a “blessed” crate. The Rust code is compiled to a WebAssembly file (66 KiB1).Footnotes
The Wasm esbuild bundler in the Convex CLI encodes the contents of the Wasm file as base64, so the size of the actual module is slightly larger. If we wanted to reduce the module size, we could modify the push process to accept binary WASM files. I think the module size is fine for now, because this will only be loaded when the password component functions run, which is a small fraction of a real app workload. ↩
