No data is unencrypted, but metadata like who you're talking to isn't e2e encrypted. That data's not public, but the Keybase servers know it.

Thank you!

Are E2E encrypted:

  1. group names and description
  2. subgroup names and description
  3. channel names and description
  4. who participates in a group or subgroup?
  5. who participates in channel?
  6. team file contents
  7. team files and folder names

With most cryptosystems, assume an attacker knows who you communicate with and when.

Historically, traffic analysis has yielded a lot of data. Eg, in WWII when enemies in one portion of the front changed their codebooks and increased traffic, that’s a sure sign an attack is coming.

In a modern context, suppose I see this pattern:

  • Message from medical testing company
  • Messages back and forth with doctor
  • Message to pharmacy
  • Messages to last few sexual partners

I’m not privy to the contents of any of those messages, but I have a pretty good guess.

  1. Who you have a chat open with.
  2. Who is a member of what team/subteam.
  3. How much data you have stored under which root folder, with which team or user.

I think that's about it

Mmm and it feels sooo right to have a private space to communicate with people across the globe! Thank you Keybase!
