(adjusted most commands to accept a loaded key in memory) (marshmellow) +- `hf iclass readblk` to select, authenticate, and read 1 block from an iclass card (marshmellow) +- `hf iclass writeblk` to select, authenticate, and write 1 block to an iclass card (or picopass) (marshmellow + others) +- `hf iclass clone` to take a saved dump file and clone selected blocks to a new tag (marshmellow + others) +- `hf iclass calcnewkey` - to calculate the div_key change to change a key - (experimental) (marshmellow + others) +- `hf iclass encryptblk` - to encrypt a data block hex to prep for writing that block (marshmellow) - ISO14443a stand-alone operation with ARM CFLAG="WITH_ISO14443a_StandAlone". This code can read & emulate two banks of 14a tag UIDs and write to "magic" cards (Craig Young) - AWID26 command context added as 'lf awid' containing realtime demodulation as well as cloning/simulation based on tag numbers (Craig Young) - Added 'hw status'. This command makes the ARM print out some runtime information. (holiman) - Added 'hw ping'. This command just sends a usb packets and checks if the pm3 is responsive. Can be used to abort certain operations which supports abort over usb. (holiman) - Added `data hex2bin` and `data bin2hex` for command line conversion between binary and hexadecimal (holiman) +- Added 'hf snoop'. This command take digitalized signal from FPGA and put in BigBuffer. (pwpiwi + enio) - Added Topaz (NFC type 1) protocol support ('hf topaz reader', 'hf list topaz', 'hf 14a raw -T', 'hf topaz snoop'). (piwi) - Added option c to 'hf list' (mark CRC bytes) (piwi) - ### Changed +- changed `lf config t ` to be 0 - 128 and will trigger on + or - threshold value (marshmellow) +- `hf iclass dump` cli options - can now dump AA1 and AA2 with different keys in one run (does not go to muliple pages for the larger tags yet) - Revised workflow for StandAloneMode14a (Craig Young) - EPA functions (`hf epa`) now support both ISO 14443-A and 14443-B cards (frederikmoellers) - 'hw version' only talks to ARM at startup, after that the info is cached.
