Mifare 4K change of keys in trailing block returns error "99" using ACR1252 and pyscard

We receive Mifare 4k cards from a supplier who pre-encodes each sector trailer as follows:

Turns out the access bit subsequently set by the supplier ff0780 means you need to authenticate the read_key (Key A) in order to write to the trailer block. Very counterintuitive, but works for Mifare 4K card where the access bit was previously set to ff0780:

Converting dynamic data to hex in array

Asked 2021-Mar-09 at 20:29

I am working on a smartcard in python and using pyscard library. I have the following data:

WRITE_PREF = [0X80, 0X12, 0X00, 0X01, 0X12, 0X01, 0X00, 0X00, 0X20, 0X00, 0X00, 0X00]

I am receiving random data(of length 10) in string format. After conversion to hex, I get the array with hex values of the random string data.

Problem: The array of hex values has the values in string form.

Example: ['0x33','0x32'....]

When I append WRITE_PREF and this hex data, I get the array like this:

[128, 18, 0, 1, 18, 1, 0, 0, 32, 0, 0, 0, '0x33', '0x32']

I convert the first part to hex and replace the array values of integer with the hex ones. When I transmit data using the command:

You have a str representing a hexadecimal number, let's turn that into an int. We save space using int, also int is flexible. We can choose how to represent this int.

Python converting a hexString

Asked 2020-Jul-23 at 14:26

Working with NFC with pyscard I received a hexstring like this "01 CB"

I need to convert it to something like that b'\x01\xCB'

I know it is a 2 octet big endian and should be equal to 459.

I basically want to run that after the conversion int.from_bytes(b'\x01\xCB', byteorder='big')

Any help is appreciated, thanks

If you need just integer value you might simply remove space and treat it just like hex-number i.e.:
