将键加载到读取器易失性内存的错误

Question

我正在尝试将一个FFFFFFFFFFFF键加载到万能5321读取器的易失性内存中。但是我得到了一个错误SW1 SW2: 69 86。有人能说出原因吗？(也许万能键不支持编写易失性键？)。

以下是代码：

bcla = 0xFF;
bins = 0x82;
bp1 =0x0     // Load key in volatile memory
bp2 = 0x20  // store in the volatile memory
len = 0x6;       // Length = 6 bytes
sendBuffer[0] = bcla;
sendBuffer[1] = bins;
sendBuffer[2] = bp1;
sendBuffer[3] = bp2;
sendBuffer[4] = len;

// Now, copy the actual key to the send buffer
for (int k =0 ;k<=5;k++)
         sendBuffer[k + 5] = str3[k]; // This will copy FFFFFFFFFFFF key


// then make call to scardtransmit.. also set length of send buffer to 11

Answer 1

69 86表示"Command not Allowed"。

试试这个..。

CLA = FF

INS = 82

P1 = 00

P2 = 60/61 (键Id，键A为60，密钥B为61 )

Lc = 06 (数据字段中键的长度)

数据字段=键的值(以6个字节为单位)

示例：

FF 82 00 60 06 FFFFFFFFFFFF
