authentication key or encryption key

[GoogleCodeExporter]

Hi everyone,

I want to make a program that accesses a DESFire and I have a doubt function 
mifare_desfire_authenticate(MifareTag tag, uint8_t key_no, MifareDESFireKey 
key). This function must be given as an argument MifareDESFireKey structure, 
this structure is the variable data, which I think is the encryption key. This 
data, is it the authentication key (rnda with rndb) or the encryption key (the 
key to the data to transfer)???

Thanks

Another question,

inside the mifare_desfire_authenticate, where use the variable "key->data"??

In the sub-function mifare_cbc_des and mifare_des don't use
