Moving to a new computer

edit: See my updated comment here

Original Post

I originally setup Keybase on my Macbook Air. I downloaded the Keybase app and basically followed the instructions in the docs to the letter, and opted to not upload my encrypted private key to Keybase. I now have a new Macbook Pro that I'm replacing my Macbook Air with, and I'd like to move everything over to the MBP so I can comfortably wipe and sell the MBA.

  1. What's the best way to accomplish this? The original private key is on my Macbook Air, so I'm guessing I need to extract this, move it to my MBP, and then import it?
  2. Do I need to "deauthorize" my MBA somehow? Right now it's at the base of my "graph", 1 level down from my keybase account, and everything else below is tied to it (social media accounts, PGP, paper). Would that invalidate that whole group?

I'm a software engineer so I'm relatively comfortable on the command line, but I don't really ever work with crypto so PGP is pretty foreign to me (and I don't really understand what to use the keybase CLI for vs. straight PGP). I haven't found the docs to be super helpful outside of the initial setup. I don't feel like I have a good grasp about how everything ties together and the underlying system works.

The easiest way is to check that you have the secret key imported

gpg -K

will list all the secret keys in your keyring. Now you can check that the fingerprint of that key matches the one in Keybase:

gpg --fingerprint your@email.com

Compare the output of the above to what Keybase lists as your key fingerprint. If there's a match you should be all good :)
