i use nip-17 and nip-4e

nostr:nprofile1qqsv0l5jlqx9zmqv2jc4arf9dtq89qgrdkf5ag0l88asek9ql4nhwdsjk0tav nip04 is the original and it leaks metadata: the relay still sees which two keys talked and when, even with the body encrypted. nip17 seals the message and then gift wraps it under a throwaway key, so the relay gets an enve...

The short version: NIP-04 is officially deprecated in favor of NIP-17, which gift wraps messages so the metadata stays private. The catch is support is uneven, so some clients send both, a NIP-17 copy plus a NIP-04 fallback for clients like Damus and Primal that lack it.

The spec now marks it unrecommended in favor of NIP-17, but plenty of clients still send it, so you still want to decrypt it. NIP-17 is the current direction, built on...
