Subject: "hf mf ekeyprn d" doesn't works properly (#904)
X-Git-Url: http://git.zerfleddert.de/cgi-bin/gitweb.cgi/proxmark3-svn/commitdiff_plain/1d4b67cb3daf01ae9908443bc1b0fd32a25060d8?hp=5a03ea993fea2573f0e4f6002c0bca8b2cda003c

"hf mf ekeyprn d" doesn't works properly (#904)

FIX: command "hf mf ekeyprn  d" doesn't use the correct offset to locate the A key in data[] array and record the 2 last bytes followed by 4 0x00 instead of the 6 good bytes (All the A keys are corrupted in file dumpkeys.bin). B keys are not affected.
