683cbdf64f Rename mifare_desfire_authenticate.c to mifare_desfire_crypto.c. 2010-12-18 02:50:38 +00:00

d098bf623f Add support for authentication using 3K3DES. 
Please note that according to the NXP documentation of the Mifare DESFire EV1,
the mifare_desfire_authenticate_iso() function can be used using either 3DES or
3K3DES keys.  The former has not been tested yet and is likely not to work. To
word it differently, this is a 3K3DES crypto support, not a ISO authentication
support...

a6e52db696 Workaround invalid write in read_data () (sic) 
This has to be improved to some extend in the near future (hence the FIXME).

5b55528008 Silent down the compiler. 
The create_application() function has iso_ parameters for creating ISO
application but this mode is not available yet so the code is unused which
annoys the compiler when told to be somewhat strict.

e0a28547fd Reset session key in mifare_desfire_select_application(). 
For Mifare DESFire EV1 support, we need to know when the user has called
mifare_desfire_select_application() after being authenticated and before
authenticated again.

02c9d33ce1 Move master key detection and authentication in a convenience library. 
The autohell hack sucks and should be fixed, but I was unable to find the magic
trick to prevent automake from building broken libtool rules which produce
warnings about portability :-/.

9011bc01e3 Don't return directly if we just have a command code. 
Mifare DESFire EV1 with authentication with AES or 3K3DES keys will require to
perform CMACing on each frame, even those with just a command.  So it does not
break anything as of today, but would be a problem later on.

a643e9149d Add an offset parameter to mifare_cryto_preprocess_data() 
Some cryptographic operations are performed on the whole data frame and not
only the payload with Mifare DESFire EV1.  The solution for now is not perfect,
(one new macro wrapping another big macro) but makes the code a bit easier to
read, and with the MIFARE_DESFIRE macro rewriting as a function (at some point
in the future), the whole should be bearable :-)

16ae154b42 Don't swap the status byte in the received data. 
This have been done for consistency with other targets support, but
cryptographic operations with Mifare DESFire EV1 tags would require to swap
again this byte because MACing is performed on the following data (in this
order):
  - Plain data
  - Status
  - Padding
