Response APDU info

Total Length: variable + 2
Data Length: variable

Data	SW1	SW2
encoded info	90	00

The info returned is CBOR encoded. It has a structure similar to the following.

  AC
     01 --data--
     02 --data--
       . . .
     14 --data--

The AC means there's a map of 12 key/value pairs. Each pair is an integer followed by data encoded as specified by the integer, defined in the CTAP 2.1 standard, section 6.4.

The standard specifies integer keys from 01 to 15 (in decimal that is 1 to 21). However, the YubiKey does not support the key 15.

Most of the elements are optional, so that any one encoding may or may not have the same subset of possible key/value pairs.
