Expand description

Decides what to do with the PIN enrollment, from the algorithms of the encrypted PIN and the user key.

  • A V1 (AES-CBC-HMAC) PIN under a V2 user key is a V1 -> V2 upgrade.
  • Otherwise the PIN must be under the user key itself. A key id, when the PIN carries one, must match; V1 PINs may carry none.
