Only a Security Domain can install or uninstall Applets. And Applets can only gain very limited rights from Security Domain.
So the question you asked is impossible.

A bug in pyResMan
I am using pyResMan to send APDU commands . I found that I could input the non-hex characters, e.g. xyz, in the DATA Field of APDU command. This is a bug.
It should not allow entering non-hex characters.

Re: How to Write on a smart card?
I use JCIDE to build my applet and JCIDE shall generate the CAP file automatically under the project path(e.g. C:\workspace\test\bin\patest\javacard) if your project is built successfully. So if you just want to get the CAP file, just create a project in JCIDE , paste you applet code and build your ...

Re: How to Write on a smart card?
Are you referring to upload and install the applet into your smartcard? If Yes, you can use PyAPDUTool to do this. And then send/receive APDU command to communicate with your applet via this tool. If you need to develop an applet by yourself, this tool can help. In addition, you can look through the...

Re: How to store secure key within the smart card applet
You can use predefined arrays or applet specific installation parameter to instantiate your keys during creation of the applet. Then the private keys shall be stored.
The GP card specification has provided the ways of key loading and content loading. Please take a look at this specification.

How to speed up RSA encryption/decryption in java card
I have already completed a java card applet implementing RSA encryption/decryption in java card.
But I find that RSA 2048 takes much more time than RSA 512 and RSA 1024.
Is there any way to speed up the RSA encryption/decryption?

Re: Delete card manager applet on the java card ?
Hey there,
You can not delete the card manager, since the Card Manager is the card component responsible for all card administration and card system service functions. It handles the application management of the card.
