Updates to the functionality of iclass sim -t 6 to specifically target the last SIO block and to do it automatically.
It now checks the AIA to determine if the card is SR or SE and adjust the block to jam based on the SIO length declared in block 6 (if SE) or fixed length if SR.
Added an option for hf iclass legrec to further increase speeds by using a shorter delay of 1500 vs the default of 3390.
This seems to be stable on new silicon especially now that we're keeping the field always on.
It may be more risky for the --fast operation.
Implemented key nibble based multithreading support for hf iclass legbrute.
It takes the whole iclass keyspace based on the first 4 bits of the key value (from 0x0 to 0xF) and divides it across the number of available threads.
E.g. on a 8 threads implementation:
- thread 1 will test keys starting with 0x0 onwards
- thread 2 will test keys starting with 0x2 onwards
- thread 3 will test keys starting with 0x4 onwards
- thread 4 will test keys starting with 0x6 onwards
- thread 5 will test keys starting with 0x8 onwards
- thread 6 will test keys starting with 0xA onwards
- thread 7 will test keys starting with 0xC onwards
- thread 8 will test keys starting with 0XE onwards
1- Added a --fast option for hf iclass legrec that further increases the speed from 4.6 key updates/second to 7.4 key updates/second. This is achieved by skipping some safety checks and is a very fast but more risky operation.
2- Automated AA2 block selection based on the values in the config block
3- Other minor code cleanups
Improved the speed of hficlass legrec from 7200 keys / hrs to 17800 keys / hr by removing the need to drop the field and re-select, re-authenticate with the card at every loop.
Re-select and re-authenticate will still happen if there's a read error and a loop needs to be repeated.
### Updated
- `000001` is not the MAD Tarjeta Transporte Público AID; it is actually `010000`, so removed references to it on that AID.
- `010000` removed the `(Alternative Endian)` designation.
Many thanks in advance, and kind regards
