Hey #nostr I was thinking: is anyone developing an Android app (and related NIP) for Nostr key management, similar to Amber but, instead of relays, using local/near field connections? Like, NFC, USB/serial, Bluetooth? So it wouldn't require network connection between signing device and Nostr client?

@nprofile…7gha I'm interested in your Nostr subkeys NIP proposal https://gist.github.com/melvincarvalho/0eeba92ad49bd7f8907694751ec20cbd I was wondering if there is any update on it?

@nostr @nprofile…7gha #nostr is there a way to import a Nostr key as a subkey part of a PGP key?

I did an amazing InterRail trip to France and Spain, with some friends from Italy, back in 2002. It was our first backpacking experience, I remember we stuffed our backpacks with packs of pasta (the proper type, not the "ready to cook" one), jars of tomato, salt, garlic, peperoncino, and olive oil. For 4 weeks of nomadic camping, our diet was mainly that, plus the sporadic tuna can or chorizo to reintegrate proteins. One of those trips you can only survive when you're 19. It was the early times of the Euro, I remember how magic it felt going to a foreign country and buying grocery in cash without having to juggle currencies. Memory unlocked.

#Nostr privacy questions:
1) am I correct that events are only signed, not encrypted, and hence relays can see the content that I, user, publish and fetch?
2) Are relay connections always HTTPS-encrypted?
3) If I fetch events through relay A, and relay A requests them to relay B, does relay B know that I (user) requested that content? Or only knows that "somebody behind relay A" did?

Hey @nprofile…qgly I want to say I appreciate a lot your presence on federated/decentralized social media. May you set a good examples for all those EU official entities who still have their main presence on Facebook/Twitter.

Tomorrow I'll be at the Swiss Crypto Day in Lugano. Looking forward to this local but important event! #swisscryptoday #swiss #switzerland #cryptography #lugano

Bellissimo rant. Purtroppo non credo sia così solo in Italia. Il profilo che citi è quello che si definisce "cryptobro" e, sì, è imbarazzante. Frens, don't be like that!

I'm trying to follow https://github.com/nostr-protocol/nips/blob/master/05.md in particular at the section "Showing just the domain as an identifier" so I use _@tomgag.net in my profile's NIP-05 field. Basically I would like people to tag me with @tomgag.net rather than something@tomgag.net . Am I doing it wrong?

Amazing, thanks, I missed that! Now the CORS tester greenlights, bit I still cannot see myself as verified in both Coracle and Amethyst, I hope it's just a matter of time for the client to fetch the updated status?

Seems OK? https://tomgag.net/.well-known/nostr.json

Can someone explain me why my #NIP-05 verification doesn't seem to work? I am using a JSON file at my domain tomgag.net but I see a red exclamation mark next to it (on #Amethyst )

Let's give this a try. #nostr sounds cool, I like the idea. I don't like too much that apps can bridge profiles from other media and make them look like the real thing. For example, this ( npub1un4zcpgku6z6cgaqd67haeq4mym8u5teeqdw5r4kaa5eye8x8vcs87tqn3
tomgag@infosec-exchange.mostr.pub ) is a bridge to my (legit) #mastodon account ( @tomgag @infosec.exchange ). A bit confusing if you ask me, because I do not control the private key for that bridge, you have to trust @mostr.pub to not impersonate accounts.
