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()  alo-
       cate 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.
