While powerful, these plugins required explicit user permission, were blocked on mobile devices, and were deprecated in favor of WebAssembly around 2019.
While this is pure JS, advanced users can load a Wasm build of libsodium ( libsodium-wrappers ) for higher performance. For the keyword nacl-web-plug-in , this serves the same functional role. nacl-web-plug-in
