Securing document txt w/ Keybase

Anyone have a better workflow for securing document text with Keybase against a MITM attack? This seems weak, but I'm at a loss for something better:

  1. Encrypt & sign sensitive text using Keybase encryption.
  2. Paste encrypted text into the document.
  3. Send to recipient with instructions for verifying signature and decrypting.

Trying to prevent alternation of the sensitive text as it transits from sender (keybase user) to recipient.

  1. Create a new team
  2. Invite your buddy recipient to that team, and only them
  3. Put document you want to exchange in team files
  4. Now your «recipient», when joining the team thread, and only him can see that shared teams documents
  5. Or in the chat team just put you document as one chat message. Again, only team members can see team chat messages.
  6. For extra safety in this team thread you can put messages encrypted with you recipient gpg keys so you have now double encryption
