Without the cap file, how can I operate the applets?

Post by mikegigom » Fri Dec 04, 2015 10:36 pm

I know that my javacard has 3 applets installed. Now I would like to select one among the three, but I don't have these applets'CAP file. So

1. Is there any steps to get the applets- AID without having the cap file?
2. Is there a way to select the applet without its AID?

A1:
pyApdutool can help you get all the packages' or applets' AID in java card even though you don't have the cap file.



A2: If you don't know the AID of the applet, you have no way to select it.

The GET STATUS command P1=0x10 can get information of "Executable Load Files and their Executable Modules only."
So you can get the package AID and applet AID from card use GET STATUS command.

You can do following now:
1 Install the applet instance;
2 Delete the package;
sense and simplicity
