Sure, but consider this:<p>Do you know what stops all passive attackers and most active attackers? TLS.<p>Do you know what WebCrypto adds that TLS doesn&#x27;t? Nothing.<p>That&#x27;s why this is useless. Just use TLS correctly and you&#x27;re better off.<p>Now, reframe this as &quot;desktop application that uses libsodium in a protocol designed by cryptography engineer&quot; and suddenly my interest is piqued.
