---Suggestions of improvement:
|

--- Add support another types of dumps: BIN, JSON
|

--- Maybe it will be not only as `mfc_gen3_writer`, like a universal dump manager.
|
||||
--- Add undependence from the operation system. At the moment code not working in Linux.
|
||||
--- Add more chinesse backdoors RAW commands for UID changing (find RAW for the 4 byte familiar chinese card, from native it soft: http://bit.ly/39VIDsU)

-- iceman notes:
|

-- doesn't take consideration filepaths for dump files.
|

-- doesn't allow A keys for authenticating when writing
|

-- doesn't verify that card is magic gen3.

That's script gives for you a easy way to write your an *.eml dumps, using a Proxmark 3.
|
||||
It's working for 4 and 7 bytes NXP MIFARE Classic 1K cards.
|
||||
The script has including an injection of UID changig for the Chinese Magic Cards GEN 3.
|
||||
|
||||
Whith choosen an *.eml file you can do:
|
||||
The script gives you a easy way to write your *.eml dumps onto normal MFC and magic Gen3 cards.
|
||||
|
||||
1. Write it to the equals of current card UID.
|
||||
2. Write it to anther card with changable UID.
|
||||
3. Send command to lock UID for the Chinese Magic Cards GEN 3.
|
||||
4. Erease all data at the card and set the FFFFFFFFFFFF keys, and Access Conditions to 78778800.
|
||||
Works with both 4 and 7 bytes NXP MIFARE Classic 1K cards.
|
||||
The script also has the possibility to change UID and permanent lock uid on magic Gen3 cards.
|
||||
|
||||
It supports the following functionality.
|
||||
|
||||
1. Write it to the same of current card UID.
|
||||
2. Write it to magic Gen3 card.
|
||||
3. Change uid to match dump on magic Gen3 card.
|
||||
4. Permanent lock UID on magic Gen3 card.
|
||||
5. Erase all data at the card and set the FF FF FF FF FF FF keys, and Access Conditions to 78778800.

||||

||||
Script works in a wizard styled way.
