The 1-byte block address (adr)
The 4-byte card serial number (uid)
It provides as output :
The 6-byte Mifare key specific to the couple card + address (Ku).

b. Diversification based on UID only
If this option is selected, the
adr
input parameter is fixed to
h
00 whatever the
block to be read is.
c. Diversification based on UID and address
If this option is selected, the
adr
input parameter is the Mifare sector number
(not the block).
Here’s an example with a Mifare 1k card :
Data is located on block 29,
Block 29 belongs to sector 7 (29 / 4),
The diversification algorithm will be fed with adr = 7.
Here’s an example with a Mifare 4k card :
Data is located on block 231,
Block 231 belongs to sector 38 (32 + (231-128) / 16),
The diversification algorithm will be fed with adr = 38.
