[Pcsclite-muscle] Omnikey 5022 CL and authentication Ultralight C

[Sjaak Paridaens]

The Omnikey AG 5022 CL has a Software developer guide with specific example
code to authenticate to a Mifare Ultralight-C card (section 5.4.3 in the
guide). The guide suggests to split the 16 bytes 3DES key for the
authentication into two parts, load the keys via SCardControl() into key
position 0 and 1 of the reader and gives the reader the instruction to
authenticate. Problem is that the reader has only 6 bytes of memory
available, so I got an 0x6989 key length error back. The example code in
the developer guide is meant for Mifare Classic authentication, is my
impression. Not for authentication with an Ultralight-C.

Wich leaves the question open how to authenticate to an Ultralight-C card
with the Omnikey 5022. Anybody who knows the trick? Or has a pointer into
the right direction?
