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).
