I think so, updated

I think this approach is reasonable. It may be worth considering feature-detecting the availability of UInt8Array.{to,from}Base64()—or using Buffer.toString('base64') in Node < v25—to adopt platform-native encoding/decoding when available. In theory that should be more efficient as it avoids the intermediary "byte string", but I don't know if it makes an actual difference in practice.

I think the same, we can do it in a follow-up PR since in my local tests I found a significant speed difference
