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

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

A mad can be written to a Mifare Classic tag using () 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 () and changed using ().

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

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

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.
