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).

从 Advanced Topics 文档以及关于可转换为 WASM 的稳定加密库的相关 Zulip 讨论开始。确定值得记录的项目和使用模式，然后描述风险、测试限制以及主机端替代方案。完成的标准是：页面能将读者引导至相关项目，同时清楚说明它们的成熟度和安全性考量。
