See this table for information on each of the tags. There is a difference between that table and the data provided for Set Device Info, namely the lock code. The lock code is 16 binary bytes.

If there is no lock code, and the caller wants to set one, provide it in the data under the tag 0A. For example,

From no lock code to lock code

    0A 10
       9A 30 B5 86 27 F1 1D 99
       40 7C 4E 14 03 BD 82 17

If there is a lock code already set, provide it under the tag 0B.

    0B 10
       9A 30 B5 86 27 F1 1D 99
       40 7C 4E 14 03 BD 82 17

To change the lock code, provide the current code under the 0B tag and the new lock code under the 0A tag.

    0B 10
       9A 30 B5 86 27 F1 1D 99
       40 7C 4E 14 03 BD 82 17
    0A 10
       71 08 B4 96 AC 38 64 F2
       81 D0 48 55 B2 EA 07 73

To remove the lock code (set the YubiKey so that a lock code is no longer needed), set the new lock code to all 00 bytes.

    0B 10
       71 08 B4 96 AC 38 64 F2
       81 D0 48 55 B2 EA 07 73
    0A 10
