Expand description

Credential process JSON protocol version.

If the protocol needs to make a breaking change, a new protocol version should be defined (`PROTOCOL_VERSION_2`). This library should offer support for both protocols if possible, by signaling in the `CredentialHello` message. Cargo will then choose which protocol to use, or it will error if there are no common protocol versions available.
