We really need private group messages in Nostr

For now your followers kind of act like that. For me its mostly bitcoiners and when the gun guys make it over I'll follow them too.
Non penso siano così necessari. Ma brutti non sono 🤙
The Amethyst_v0.15.3 software, the Upload function of the attachment cannot be used normally.
What do you mean? Can you record a video?
Upload image
do you understand?
Oh. So it's failing to upload? Does it happen with all images and file types? I know that imgur has some limits in file size...
I haven't used this function successfully once. I don't know why. It is recommended that the next version support images, videos and other file types
In addition, the keyword search function should be supported. For example, # news
Thank you very much for the open source software you provided us. I hope it will get better and better。
💯
That would be a very nice thing to have!
How about:
1. Encrypt message with shared symmetric cryptography. Use key "k".
2. Enrypt "k" with each participants public key.
3. Send event with encrypted message and encrypted keys. It shall also contain the public key of participants.
We do. And Amethyst needs to be a little faster please. Even typing is pain in the a** 😔😔
yes, if you want it to be the platform to rule them all
yes, it's really needed
There's a lot of talk about your post.

Those kinds of things will be built once a better nip for encrypted messages than nip4 is decided upon. Nip4 has issues and is inadequate, it needs a successor.
It’s a tough problem to solve but I agree. I’ve been keeping up on the private groups work in secure scuttlebutt. I bet we can learn a lot from how they are approaching it.
We need something like MLS + metadata encryption. Like this: https://eprint.iacr.org/2022/1533.pdf
How about this..
- User creates a group chat
- The client creates a private/public keypair for the group
- User invites others to join, which sends them the keypair
- When a user posts to the group chat, their inner message is signed by their private key. That signed message is wrapped in an outer message signed by and encrypted with the group chat private key
- Timestamps are used to properly order messages in the group chat
That would keep the group chat membership private. Subscribed clients watch for new messages sent to the group's npub.
