问题描述
我有一个DESfire Ev1 1.3版卡，我正在尝试使用ISO7816 apdu样式选择文件.
I have a DESfire Ev1 version 1.3 card and I'm trying to select a file using ISO7816 apdu style.
我有一个文件，有一个辅助文件A0 A1 A2，我可以使用纯模式或打包模式进行选择:
I have one file, with aid A0 A1 A2 and I can select it using both native or wrapped mode:
母语:
-> 5A A0 A1 A2
<- 00
包装:
-> 90 5A 00 00 03 A0 A1 A2 00
<- 91 00
但是，如果我尝试使用ISO7816样式进行选择，则总是会出现找不到文件的错误:
However, if I try to select it using ISO7816 style, I always get a file not found error:
ISO7816:
-> 00 A4 04 00 03 A0 A1 A2 00
-> 6A 82
使用ISO apdu时，AID是否采用其他格式?如何使用它来选择此AID?
When using ISO apdu, is the AID in a different format? How can I select this AID using it?
推荐答案
0x00 0xA4 0x04 0x00 0x07 0xD2 0x76 0x00 0x00 0x85 0x01 0x00
**编辑**
改为尝试ISO SELECT DIRECTORY:
ISO SELECT DIRECTORY命令的功能兼容 使用本机DESFire选择应用程序"命令.
The functionality of the ISO SELECT DIRECTORY Command is compatible with the native DESFire "Select Application" command.
所以:
0x00 0xA4 0x04 0x00 0x03 0xA0 0xA1 0xA2
(这在下一页上，也许是您最初想要的.)
(this was on the following page, and probably what you wanted in the first place.)
我认为这与您所拥有的相同，但最后要减去NUL.
I think this is identical to what you had, minus the NUL at the end.
