Improvements/Fixes to 14443 sniffing/snooping
- fixed a circular buffer rollover bug in iso14443a.c
- fixed 7 Byte UID handling in hf mf sniff
- fixed "cannot append" error in hf mf sniff d
- fixed hint on mfkey32 in hf mf sim x
- fixed hf mf sniff sometimes showing rogue data from previous calloc
- improve snooping/sniffing by syncing modulation detector window with reader signal (hi_iso14443a.v)
- code cleanup of hi_iso14443a.v

Added an important notice.
Moving the repository from google code to GitHub is up for discussion!
Please check out the following thread and post your comments...

Discussions will close on March 31st.
More robust iso14443a sniffing/simulation functions by
- iso14443a.c: less strict Miller/Manchester decoders
- FPGA hi_iso14443a.v: syncing on external readers' clock when simulating and sniffing.
- fixed iso1443a ManchesterDecoder in order to fix broken Snoop/Sniff
- enhanced tracing: hf 14a list now shows meaningful timing information. With new option f it also shows the frame delay times (fdt)
- small fix for hf 14b list - it used to run into the trace trailer
- hf 14a sim now obeys iso14443 timing (fdt of 1172 or 1234 resp.)
Note: you need to flash FPGA as well.

Various improvements on the Mifare1kSimulation. Fixed issue with tracebuffer not being cleared, fixed issue with 'static' errors, added modes for doing reader-only attack, added interactive mode, added possibility to set UID from cmdline, either 7-byte or 4-byte. See http://www.proxmark.org/forum/viewtopic.php?id=1529 and http://www.proxmark.org/forum/viewtopic.php?id=1649&p=3 for some more background and discussion
- improved reader sensitivity for 14443a cards (FPGA change!)
- implemented ISO 14443A anticollision loop
See http://www.proxmark.org/forum/viewtopic.php?id=1797 further details
Changed html template, in order to make it more generic and be usable on other types of data than mifare, now supports different highlighters. Implemented are NDEF and Mifare
Changes to how dumping is performed, now utilises a library. This is in preparation for a more generic dumping of different types of cards. Also added functionality to html-dump .eml-files

with the declaration of 'uint8_t destination[8]', 'destination' is already a pointer, don't try to get the address of it by using '&destination', then you will get a pointer to a pointer.
Committed mifare_autopwn.lua. For more infromation, see http://martin.swende.se/blog/Proxmark_Scripting_1.html and http://martin.swende.se/blog/Proxmark_Scripting_2.html
Reworked how to call 'standard' stuff from within lua scripts, so now it's much simpler both in lines of code and usage. A script can now call core.console('hf mf nested 1 0 a ffffffffffff') in order to execute anything via the old command line parser
Added a utility script to convert a 'dumpdata.bin'-file into the 'eml'-format that the emulator uses. Did not find any built-in way to do this, perhaps such functionality already exists.. ?
Added a utility which takes a mifare-dumpfile and creates a html-report visualising the data. The html-dump is self-sufficient and standalone .. part 2
Add support in 'hf mf mifare' for some unlicensed/compatible mifare card which always answer NACK.
Change the 'nttmp' start from nt distance 500 to 100 in mifarecmd.c to compatible some unlicensed/compatible mifare card.
Moved script libraries into lualibs/folder, and added a patch to include the folder in the LUA_PATH (a.k.a package.path). See http://proxmark.org/forum/viewtopic.php?id=1750 for more details
Major rework of hf mf nested:
- PM: used GetCountMifare in MifareNested() for improved timing accuracy and to deliver better quality nonces
- PM: MifareNested now delivers exactly two different nonces to avoid time consuming multiple lfsr_recovery32() on client side
- Client: replaced quicksort by bucketsort in crapto1.c which is faster
- Client: use multithreading (two parallel calls to lfsr_recovery32())
- Client: fixed a small bug in mfnested() (always showed trgkey=0)
- Client: introduced a mutex for PrintAndLog() to avoid interlaced printing
Minor rework of hf mf chk:
- Avoid time consuming off/on cycles. Send a "halt" instead.
