如何用pyscard编写智能卡

我正在使用读写器acr38f,我的智能卡是SLE4418。如何在智能卡上读写文本?

例如:Hello World!

apdu = [0XFF, 0X20,0x00,0x00,0x02, 0x00, 0x00]

response, sw1, sw2 = cardservice.connection.transmit( apdu )

apdu = [0XFF,0xA4,0x00,0x00,0x01,0x05]
response, sw1, sw2 = cardservice.connection.transmit( apdu )




apdu = [0XFF,0XB2,0X00,0xA7,0X09]
response, sw1, sw2 = cardservice.connection.transmit( apdu )
print response


apdu = [0XFF, 0XD0,0x00,0xA7,0x09,0xA7,0x02,0xA7,0x02,0xA7,0x02,0xA7,0x02,0xA7] 
response, sw1, sw2 = cardservice.connection.transmit( apdu )

卡响应:

connecting to ACS CCID USB Reader 0
ATR 3B 04 92 23 10 91
>  FF 20 00 00 02 00 00
<  00 00 00 90 0 
>  FF A4 00 00 01 05
<  []  90 0 
>  FF B2 00 A7 09
<  FF FF FF FF FF FF FF FF FF 90 0 
[255, 255, 255, 255, 255, 255, 255, 255, 255]
>  FF D0 00 A7 09 A7 02 A7 02 A7 02 A7 02 A7
<  []  90 0

我没有硬件来测试,但这会让你开始:

与智能卡通信涉及发送APDU(智能卡应用协议数据单元)命令和接收APDU响应。

命令apdu通过读写器(ACR38F)发送,由一个4字节的头和数据(以及关于数据大小和响应大小的信息)组成

Field    Len Description
--------------------------------------------
CLA     (1) Instruction Class
INS     (1) Instruction Code
P1-P2   (2) Instruction Parameters
Lc  (0,1,3) Number of data bytes to follow
DATA    (*) Data to be transmitted
Le    (0-3) Maximum response bytes

答复包括:

Field    Len Description
--------------------------------------------
DATA    (*) Data to be transmitted
SW1-SW2 (2) Command status

SLE4418, in order to write data,的情况下,值应如下所示:

  • 克拉=00
  • INS=D6
  • P1=存储字节的内存地址偏移量的MSB
  • P2=存储字节的内存地址偏移的LSB
  • Lc=要存储的字节长度
  • DATA=要存储的数据
  • Le=(空)

因此在代码中:

WRITE = [0x00, 0xD6]
STARTMSB = [0x00] #change to where on the card you would like to write
STARTLSB = [0x00] #same here
MEM_L = [0x01]
DATA = [0x01]

cardservice.connection.connect()
apdu = READ + STARTMSB + STARTLSB + MEM_L + DATA
response1, sw1, sw2 = self.cardservice.connection.transmit( apdu )
