From 0956e0dba568044b63636151999c817e76f47964 Mon Sep 17 00:00:00 2001 From: iceman1001 Date: Tue, 10 Nov 2015 11:45:45 +0100 Subject: [PATCH] FIX: an error that I introduced to the csetblock command with wrong length of crc calcs. CHG: variable name in csetblock change. just trying to be consistant. ADD: code clean up in hf 14a, added some help text methods. --- armsrc/mifarecmd.c | 6 +-- client/cmdhf14a.c | 104 ++++++++++++++++++++++----------------------- client/cmdhf14a.h | 4 +- client/cmdhfmf.c | 8 ++-- 4 files changed, 61 insertions(+), 61 deletions(-) diff --git a/armsrc/mifarecmd.c b/armsrc/mifarecmd.c index ba3034bf..1e42d5b4 100644 --- a/armsrc/mifarecmd.c +++ b/armsrc/mifarecmd.c @@ -1092,8 +1092,8 @@ void MifareCSetBlock(uint32_t arg0, uint32_t arg1, uint8_t *datain){ OnErrorMagic(4); }; - memcpy(data, datain, sizeof(data)); - AppendCrc14443a(data, sizeof(data)); + memcpy(data, datain, 16); + AppendCrc14443a(data, 16); ReaderTransmit(data, sizeof(data), NULL); if ((ReaderReceive(receivedAnswer, receivedAnswerPar) != 1) || (receivedAnswer[0] != 0x0a)) { @@ -1118,8 +1118,6 @@ void MifareCGetBlock(uint32_t arg0, uint32_t arg1, uint8_t *datain){ uint8_t workFlags = arg0; uint8_t blockNo = arg1; - Dbprintf("ICE :: CGetBlocks Flags %02x", workFlags); - // variables uint8_t data[MAX_MIFARE_FRAME_SIZE]; uint8_t receivedAnswer[MAX_MIFARE_FRAME_SIZE]; diff --git a/client/cmdhf14a.c b/client/cmdhf14a.c index 33197cf5..f94296c0 100644 --- a/client/cmdhf14a.c +++ b/client/cmdhf14a.c @@ -127,6 +127,48 @@ char* getTagInfo(uint8_t uid) { return manufactureMapping[len-1].desc; } + +int usage_hf_14a_sim(void) { + PrintAndLog("\n Emulating ISO/IEC 14443 type A tag with 4 or 7 byte UID\n"); + PrintAndLog("Usage: hf 14a sim t u x"); + PrintAndLog(" Options : "); + PrintAndLog(" h : this help"); + PrintAndLog(" t : 1 = MIFARE Classic"); + PrintAndLog(" 2 = MIFARE Ultralight"); + PrintAndLog(" 3 = MIFARE Desfire"); + PrintAndLog(" 4 = ISO/IEC 14443-4"); + PrintAndLog(" 5 = MIFARE Tnp3xxx"); + PrintAndLog(" 6 = MIFARE Mini"); + PrintAndLog(" 7 = AMIIBO (NTAG 215), pack 0x8080"); + PrintAndLog(" u : 4 or 7 byte UID"); + PrintAndLog(" x : (Optional) performs the 'reader attack', nr/ar attack against a legitimate reader"); + PrintAndLog("\n sample : hf 14a sim t 1 u 1122344"); + PrintAndLog(" : hf 14a sim t 1 u 1122344 x\n"); + return 0; +} +int usage_hf_14a_sniff(void){ + PrintAndLog("It get data from the field and saves it into command buffer."); + PrintAndLog("Buffer accessible from command 'hf list 14a'"); + PrintAndLog("Usage: hf 14a sniff [c][r]"); + PrintAndLog("c - triggered by first data from card"); + PrintAndLog("r - triggered by first 7-bit request from reader (REQ,WUP,...)"); + PrintAndLog("sample: hf 14a sniff c r"); + return 0; +} +int usage_hf_14a_raw(void){ + PrintAndLog("Usage: hf 14a raw [-h] [-r] [-c] [-p] [-a] [-T] [-t] [-b] <0A 0B 0C ... hex>"); + PrintAndLog(" -h this help"); + PrintAndLog(" -r do not read response"); + PrintAndLog(" -c calculate and append CRC"); + PrintAndLog(" -p leave the signal field ON after receive"); + PrintAndLog(" -a active signal field ON without select"); + PrintAndLog(" -s active signal field ON with select"); + PrintAndLog(" -b number of bits to send.
