假设我想向 Mifare Classic 进行身份验证。
我如何知道要发送到卡的确切 APDU 类型?
例子。
这段代码:
bcla = 0xFF;
bins = 0x86;
bp1 = 0x0;
bp2 = 0x0; // currentBlock
len = 0x5;
sendBuffer[0] = bcla;
sendBuffer[1] = bins;
sendBuffer[2] = bp1;
sendBuffer[3] = bp2;
sendBuffer[4] = len;
sendBuffer[5] = 0x1; // Version
sendBuffer[6] = 0x0; // Address MSB
sendBuffer[7] = currentBlock;
if(keyradioButton->Checked==true) // Address LSB
sendBuffer[8] = 0x60; // Key Type A
else if(keynumberradioButton->Checked ==true)
sendBuffer[8] = 0x61; // Key Type B
sendBuffer[9] = keynumber; // Key Number
sendbufferlen = 0xA;
receivebufferlen = 255;
//Invoke the Transmit command
retval = SCardTransmit(hCard, // A reference value returned from the SCardConnect function.
&sioreq,
sendBuffer, // Send buffer
sendbufferlen, // Send buffer length
&rioreq,
receiveBuffer, // Receive butter
&receivebufferlen); // Length of received buffer
是一个尝试向 Mifare Classic 进行身份验证的示例程序。我的问题基本上是,我怎么知道要向卡发送什么样的 APDU?例如,我怎么知道应该是什么sendBuffer
?
