DESCRIPTION

Mifare Application Directories (MAD) can be easily manipulated using the mad_*() set of functions.

A mad can be loaded form a Mifare Classic tag using mad_read() or generated from scratch using mad_new() and providing the version of the mad to generate. After using a mad, the memory can be reclaimed using mad_free().

A mad can be written to a Mifare Classic tag using mad_write() and providing the B keys required for writing to sectors 0, key_b_sector_00, and the one required for writing to sectors 10, key_b_sector_10. When writing a MAD version 1 mad, the key_b_sector_10.

The version of a MAD mad can be read using mad_get_version() and changed using mad_set_version().

The card publisher sector number cps can be read read using mad_get_card_publisher_sector() and writen using mad_set_card_publisher_sector().

Sectors allocation in the mad is handled by the mad_get_aid() and mad_set_aid() functions. These functions fill-in or read the Application Identifier, aid for the given sector.

RETURN VALUES

The mad_new() function return NULL on failure and allocates memory that has to be freed using mad_free() on success. Unless stated otherwise, all other functions return a value greater than or equal to 0 on success or -1 on failure.
