This would be really cool. I'm hoping this eventually means we don't have to call the dynamic Blake3 import in Signify as is done here:

        const b3 = await import('blake3/browser-async');
        await b3.default(
            'https://cdn.jsdelivr.net/npm/[email protected]/dist/wasm/web/blake3_js_bg.wasm'
        );
        await _sodium.ready;

Looks like we still need to await _sodium.ready though. I haven't heard of a Libsodium implementation in pure JS that works for us.

@AlexAndrei98 , the changes in the PR are replicated in #16, which more broadly addresses the dependency issue . It would be cleanest to close this PR out and just merge the other.
