DESCRIPTION¶
The
mifare_desfire_key_*() family of
functions allows management of Mifare 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.
