the "application specific data" events are always gobbledygook base64 encrypted text
i haven't inspected them closer to ensure they actually consist of a pubkey, nonce prefix and encrypted blob that can be unencrypted by the combination of one's private key and that nonce
there is zero ... i mean zero... understanding of cryptography, as far as i can see, in 95%+ of the nostr dev community
when i joke about making NIP-42 work in nostrudel it's not all a joke... i know the signature checking works, i know that the encryption and decryption works, i am making assumptions based on the fact that i don't know javascript well enough to actually audit how the code running, and yes i don't trust it at all, i hate javascript and thus distrust everything it does
