如何用pyscard写智能卡
[英]How to write smart card with pyscard
问题描述
I'm using reader/writer acr38f and my smart card is SLE4418.
我正在使用读写器 acr38f，我的智能卡是 SLE4418。 How do I read and write text to my smart card?如何在智能卡中读取和写入文本？
For example: Hello World!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 )
card response:卡片回复：

I do not have the hardware to test this, but this should get you going:我没有硬件来测试这个，但这应该让你继续：
Communicating with smart cards involves sending APDU (Smart Card application protocol data unit) commands and receiving APDU responses.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。
Command APDUs are sent through the reader/write (your ACR38F) and consists of a 4-byte header followed by data (and info about the data size and response size)命令 APDU 通过读/写器（您的 ACR38F）发送，由 4 字节 header 后跟数据（以及有关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
The response consists of:响应包括：
Field Len Description
--------------------------------------------
DATA (*) Data to be transmitted
SW1-SW2 (2) Command status
In the case of the SLE4418, in order to write data, the values should be as follows:对于SLE4418，为了写入数据，值应如下所示：
- CLA = 00 CLA = 00
- INS = D6 INS = D6
- P1 = MSB of memory address offset to store bytes P1 = memory 地址偏移存储字节的 MSB
- P2 = LSB of memory address offset to store bytes P2 = memory 地址偏移存储字节的 LSB
- Lc = length of bytes to store Lc = 要存储的字节长度
- DATA = data to store DATA = 要存储的数据
- Le = (empty)乐=（空）
So therefore in code: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 )
