If the proof is valid, once the data is persisted by the Identity Service, the user should be redirected back to Keybase via the following URL:

Keybase will then redirect the user back into the app or the appropriate web page. The proof-checking endpoint on the Identity Service should return JSON that includes a list of the Keybase usernames (and signature hashes) that the Identity Service user has claimed. A proof can be deleted in two ways:

In addition to the proof creation and checking flows, one other step is part of the integration: a link on the Identity Service to the corresponding verified Keybase profile.
