Ever thought about how to run a study group without any third‑party servers? I’ve been drafting a protocol that keeps everything encrypted end‑to‑end and still lets everyone share notes. Think we could prototype something?

Sounds exciting! I’d love to dive in. I can start sketching a secure, end‑to‑end plan, set up a shared folder that encrypts everything locally, and even draft a quick user guide. Let me know the list of tools you’re comfortable with, and I’ll keep everything organized—no risk of anyone losing a note or a password. I’ll get a timeline and checklist ready so we’re all on the same page before we prototype. How does that sound?

Nice. I’m comfortable with GnuPG for encryption, rsync for syncing, and a lightweight local server like Syncthing if we need peer‑to‑peer. Keep the guide minimal—just the commands and key management steps. I’ll review the timeline once you send it. Keep the focus tight, no fluff.

**Minimal Command Guide** 1. **Generate GPG keys** ```bash gpg --full-generate-key # choose default (RSA & RSA, 2048 bits) and set a passphrase ``` 2. **Export public keys for each member** ```bash gpg --export --armor alice@example.com > alice_pub.asc ``` 3. **Import each other’s public keys** ```bash gpg --import alice_pub.asc ``` 4. **Encrypt a file for the group** ```bash gpg --encrypt --recipient alice@example.com --recipient bob@example.com notes.txt ``` (Creates notes.txt.gpg) 5. **Decrypt a received file** ```bash gpg --decrypt notes.txt.gpg > notes.txt ``` 6. **Sync notes with rsync (over SSH)** ```bash rsync -avz -e ssh notes.txt.gpg alice@example.com:/path/to/shared/ ``` 7. **Set up Syncthing (optional)** - Install Syncthing on each machine. - Create a shared folder in Syncthing, add the GPG‑encrypted files. - Set folder to *Read‑only* on your machine to avoid accidental edits. **Key Management Tips** - Keep the private key file (`~/.gnupg/secring.gpg` or keyring folder) in a secure, backed‑up location. - Periodically export the public key and distribute it via email or a secure channel. - If a member leaves the group, revoke their key: ```bash gpg --edit-key alice@example.com # inside gpg: revoke, save, exit ``` - Use `gpg --list-keys` to verify the status of each key. Let me know if that’s what you had in mind, and I’ll draft the timeline next.
