Note the implementations/usage patterns of crypto that are wasm-ready

A great answer popped on up Zulip that might be worth sharing more widely:

[#general > Stable crypto library which can be converted to wasm @ 💬](https://bytecodealliance.zulipchat.com/#narrow/channel/206238-general/topic/Stable.20crypto.20library.20which.20can.20be.20converted.20to.20wasm/near/504933984)

It would be great if there was a page (likely in "Advanced Topics") that pointed at some of these projects for doing crypto w/ WASM, while noting the risks and what is not yet well-tested, along with the usual solution (which is doing it in the host).

Start with the Advanced Topics documentation and the linked Zulip discussion about stable crypto libraries that can be converted to WASM. Identify the projects and usage patterns worth documenting, then describe the risks, testing limitations, and host-side alternative. Done means the page points readers to relevant projects while clearly stating their maturity and security considerations.
