     keys Manipulation Functions

LIBRARY
     Mifare card manipulation library (libfreefare, -lfreefare)

SYNOPSIS
     #include <freefare.h>

     MifareDESFireKey
     mifare_desfire_des_key_new(uint8_t	value[8]);

     MifareDESFireKey
     mifare_desfire_3des_key_new(uint8_t value[16]);

     MifareDESFireKey
     mifare_desfire_3k3des_key_new(uint8_t value[24]);

     MifareDESFireKey
     mifare_desfire_aes_key_new(uint8_t	value[16]);

     MifareDESFireKey
     mifare_desfire_des_key_new_with_version(uint8_t value[8]);

     MifareDESFireKey
     mifare_desfire_3des_key_new_with_version(uint8_t value[16]);

     MifareDESFireKey
     mifare_desfire_3k3des_key_new_with_version(uint8_t	value[24]);

     MifareDESFireKey
     mifare_desfire_aes_key_new_with_version(uint8_t value[16],
	 uint8_t version);

     uint8_t
     mifare_desfire_key_get_version(MifareDESFireKey key);

     void
     mifare_desfire_key_set_version(MifareDESFireKey key, uint8_t version);

     void
     mifare_desfire_key_free(MifareDESFireKey key);

DESCRIPTION
     The mifare_desfire_key_*()	family of functions allows management of Mi-
     fare DESFire keys.

     The mifare_desfire_des_key_new(), mifare_desfire_3des_key_new(),
     mifare_desfire_3k3des_key_new() and mifare_desfire_ades_key_new() alocate
     a new key with the	provided data value.  The key version is set to	0.

     The mifare_desfire_des_key_new_with_version(),
     mifare_desfire_3des_key_new_with_version(),
     mifare_desfire_3k3des_key_new_with_version() and
     mifare_desfire_aes_key_new_with_version() functions are equivalent	to the
     previous functions	except that the	key version is read from value (DES,
     3DES, 3K3DES) or set to version (AES).

     The version of a MifareDESFireKey can be extracted	using
     mifare_desfire_key_get_version() and changed using
     mifare_desfire_key_set_version.()

     The mifare_desfire_key_free() has to be called for	each MifareDESFireKey
     after usage to reclaim memory.

RETURN VALUES
     Key allocations functions return the allocaed key of NULL on failure.
