Expat（XMLパーサー）やWoff2（フォントパーサー）などをWASMにコンパイルしてから等価なCコードに変換することで、CやC++で書かれていて信頼できない外部入力を受け付ける必要があるライブラリをWASMのサンドボックスに入れるRLBoxという研究プロジェクトの成果がFirefox 95に投入された。

第2世代XiangShanであるNanhuはBitmanipとScalar Cryptoも実装しているのが興味深い。

実装は src/main/scala/xiangshan/backend/fu/Bku.scala や src/main/scala/xiangshan/backend/fu/util/CryptoUtils.scala あたりにある。SHA/AESとSM3/SM4の両方を実装しているところに中国産らしさを感じる。
