CAP file analyzer - easy method size acquisition
Hi all,
I want to calculate how many bytes each method I have in my JavaCard applet takes. Right now, I am deleting the body of my methods (effectively turning that into a stub) and compile, and subtract the new size from the size of my CAP before removing the method. Can there be an easier way to do this? (A tool to analyze CAP itself, maybe?)
Any directions greatly appreciated..
Regards,
Burak
hi:
i write a program that can parse CAP file, hope that is helpful to you.

Hello all,
Is there any program to analyze the cap file?
the program read the cap file and print out or make a file with cap file information by components user kindly format. like Header Component.tag = 0x01 size=0x0A .....
Thanks,

Cap file Components size limit ( ? )
Hello,
I'm wondering if there is a limitation on the Cap file internal components size.
as specified in the JVM Spec from SUN, a cap file consists on several elements (byte sequences) : Header.cap , Class.cap, StaticField.cap, etc.
Does a component have a size limit ?
I'm asking this question because I'm facing serious problem when loading Applets on Gemplus SIM cards(GemWpressoV3 ) : the load process interrupts sudenly and the card responds with 6F00 !!
For info, the Method.cap components is 11748 bytes !!
Thank you for your Help and Info
Kartagoshere is a complete description of the Cap I can't load :
Header.cap (29 Bytes)
Directory.cap (34 Bytes)
Import.cap (62 Bytes)
Applet.cap (23 Bytes)
Class.cap (94 Bytes)
Method.cap (8484 Bytes)
StaticField.cap (6312 Bytes)
ConstantPool.cap (925 Bytes)
RefLocation.cap (1411 Bytes)
Descriptor.cap (2340 Bytes) -
Analyze netmon .cap file with logparser
Hi all,
I'm trying to analyze a cap file with logparser. I'm exporting all the content of the file to a CSVfile. But when I open the CSV file, it doesn't shows source IP and destination IP for any of the packets. Whereas if I open the file with network monitor,
it does shows all the information. I'm using below mentioned query to export the data to CSV.
logparser -i:netmon "SELECT * INTO test.csv FROM test.cap"

"Known issues on Windows 7
If you are trying to parse the Netmon trace File through Logparser, the SrcIP and the DstIP fields might appear to be blank. This is a known issue with Win 7. However parsing should work just fine on a XP or a Win 8 machine."

I've been trying to parse CAP files, but having trouble figuring out these values...
In Method component: what is the number of elements in "method_info methods[]" array???
in method_info: what is the size of bytecodes[] array???
in type_descriptor_info: what is the number of elements in type_desc[] array???
many thanksSee the JCVM Specifications, the size of the structure arrays u have mentioned is not specified. If you parse these files u can do it with the help of Reference location component. If you use the pointers in C it will be easy as compared to Java.

Accessing a Static Array in one CAP file from another CAP in same project
Hi all,
I have been developing a banking application on JavaCard. So the size of the applet has grown size able and have now split the file to multiple CAP files. I have been using NXP JCOP plugin in Eclipse for development. Below are the steps done
a.) I have created multiple packages under the same project where one project has all the variable which are public static final and don't reference any other class. Also this package does not extend Applet. So it finally generates to a CAP file.
b.) Another package which imports the above package and also extend Applet is the one which has all the UI and logic related to the project. The applet uses the static array defined in the another package to show the menu on phone.
Now the problem is that when the code come to point for fetching the menu data, i have some thing like menu.length . But when the code comes to this point in debugger i get a
+6F 00 Status: No precise diagnosis.+
To cross check i put a watch on the menu variable and found that it has all the data required for showing the menu (which is of 32 byes). So now i am perplexed on why this length is giving this problem. Am i doing some thing wrong. Below is the Snip of the larger code
This code is the package which has all the constants..
package constantsPack;
import javacard.framework.APDU;
import javacard.framework.ISO7816;
import javacard.framework.JCSystem;
import javacard.framework.Util;
public class ConstantsApplet {
//menu array decleration
public static final byte[] MAIN_SETUP_MENU = {
(byte) 0x81, ConstantsApplet.CMD_DTL_LENGTH, ConstantsApplet.CMD_NUMBER, ConstantsApplet.MAIN_CMD_SET_UP_MENU, (byte) 0x00,
(byte) 0x82, (byte) 0x02, ConstantsApplet.DEVICEID_SIM, ConstantsApplet.DEVICEID_ME,
(byte) 0x85, (byte) 0x08 ,'A','B', 'C',' ','A','p','p','s',
(byte) 0x8F, (byte) 0x0D, ConstantsApplet.SB_MENU, 'A','b','c','d','e','f','g',' ','B','a','n','k',
// other constants.
}This is the package which has the applet and which uses the variables of the above package
package myPkgLib;
import constantsPack.*;
import javacard.framework.APDU;
import javacard.framework.Applet;
import javacard.framework.ISO7816;
import javacard.framework.ISOException;
import javacard.framework.OwnerPIN;
import javacard.framework.Util;
import javacard.framework.JCSystem;
public class myApplet extends Applet{
// other code
fetch(ConstantsApplet.MAIN_SETUP_MENU.length);
}Any help regarding this would be very helpful...
Regards
Prakash
Edited by: prakash on Apr 18, 2012 11:57 PMHi lexdabear,
I tried putting a function inside the library package where the static array is present, but the results are the same... Also by try catch . what exception you want to catch... i see Exception has just .equal function... Tried with ExternalException also but does not seem to enter it..
Attaching the source code compilable in eclipse below ..
package constantsPack;
public class ConstantsApplet {
public static final byte[] MAIN_SETUP_MENU = {

(byte) 0x85, (byte) 0x08 ,'A','B', 'C',' ','A','p','p','s',
(byte) 0x8F, (byte) 0x0D, 0x0F, 't','e','s','t','a','p','p',' ','B','a','n','k',
public ConstantsApplet ()
}The applet code where the above static array is used..
package smilePkgLib;

Verify user pin on a smart card & load a cap file on a card (with eclipse)
I have been able install JCWDE (Java card development Kit) successfully on eclipse.Basically all I need to do is verify user pin on a smart card.As in first set a pin and then verify it.
To begin with I have referred many tutorials (here: http://www.javaworld.com/jw-07-1999/jw-07-javacard.html?page=1) and implemented the wallet code in eclipse.I have the cap file generated and the scripts generated.I am not sure how to load it on the smart card with eclipse.
I tried to deploy the cap file but it keeps saying connected.Also when we initiate the applet I get the same result.
output:

I have also tried : http://www.cs.ru.nl/E.Poll/hw/practical.html ........ but no luck.
I have the wallet.cap ,wallet.exp ,wallet.jca ,wallet.opt create.script, select,cap-download.scripts files already generated in eclipse.
How does a successfully implemented applet code on a smart card work?How does this wallet code work if it is successfully implemented ? Does it have like some GUI which prompts the user to enter the pin?

Any help on this would highly appreciated !! :)Hi,
Thanks a lot for reply.But I am not sure as to how can I delete the simulator.
All I want to do is write a pin on the smart card and verify it.But I am not being able to deploy the cap file or initiate the applet.
Also for passing the pin correct me if I am wrong........ according to what you said and what I have understood
If the code is like this :
public static void install(byte[] bArray, short bOffset, byte bLength) {
// create a Wallet applet instance
new Wallet(bArray, bOffset, bLength);
} // end of install method
byte aLen = bArray[bOffset]; // applet data length
// The installation parameters contain the PIN
// initialization value
pin.update(bArray, (short)(bOffset+1), aLen);
Lets say my pin is : 1234
then I would pass it here.....
new Wallet(bArray, 1234, bLength); -
Hello,
I am interested in 3 question:
1. Is there any possibility to get the CAP file from a card.
2. Is CAP file backward convertible to .class or .java files? I.e. is it safe enough for distribution, to avoid the retrieval of the source code?
3. What files should be distributed for extended APIs: EXP, CAP file and stub class files? Am i right?
I appreciate any answers and advices regarding the safety of the CAP files.
Best regards,
newbie.1. Is there any possibility to get the CAP file from a card.Yes. Use google, search on "Javacard attacks" or "javacard hacks". You will find many papers and presentations on what has been done, what works, what does not.
My conclusions: Its possible. Its hard to do. Various people are working on it, so perhaps its getting easier. Vendors are making cards more resistant to attack, so perhaps its getting harder.
2. Is CAP file backward convertible to .class or .java files? No, not backward compatible, or at least not easily. Some information is lost. I have not found any open source or commercial tools for this.
See this thread: http://forum.java.sun.com/thread.jspa?threadID=5217462&tstart=0
I.e. is it safe enough for distribution, to avoid the retrieval of the source code?Probably. It will take significant effort to reverse a CAP file all the way back to Java source that will compile and execute with the same results as the original. Probably 100's of hours of work.
3. What files should be distributed for extended APIs: EXP, CAP file and stub class files? Am i right?At minimum the EXP and CAP. A developer has no way to use the CAP file without the EXP file. The EXP file contains all of the class, method and field names for the public methods/fields that the converter tool needs (there are no String names in the CAP file).
Read the JavaCard Virtual Machine specification. Its very enlightening.

conversion completed with 73 errors and 1 warnings.It seems there is a variable of type "long" in your applet. The "long" type is not supported by Java Card, so you should remove all variables with type "long".
Otherwise, without the source code, it is difficult to help you find out what's wrong. -
How to load the .cap file in a Smart Card?
Dear All,
Hello..!!
I am using JCDK 2.2 and have used Eclipse JCDK.
I have written a simple read/write applet and created a .cap file using Eclipse's Converter Java Card tool.
What is the next step to be done?
I have a smart card device and have installed its drivers.
When do the APDU commands come into picture?
Expecting help.
Thanks a lot.

SurilHi all,
Is Mr. thread starter has solved his problem?
I profit this thread to post my question. I'm working with new environment and I have problem loading cap file into my smartcard.
specification come first :-)
- My smartcard is said to be JC2.2.1 and GP2.1.1 compatible
- My code (for testing) is written in Java under eclipse Helios service 2 with JavaCard plugin (for JC2.2.2)
I compile my code with JDK 1.3 (for compatible version) and using the JC plugin to generate cap file (along with exp and jca).
My problem is exactly the same as one that was posted in this forum about 2 years ago but is not answered :-)

How do I get iTunes 10 to play movie files as their actual size?
In iTunes (10), I have several iTunes purchases/rentals as well as movie files I've created on my own and converted into .mp4 format. My problem is that I really would like to play these files as their actual size, but can't seem to get iTunes to cooperate. I'm sure there's an easy way to do this and I've tried the quick-keyboard command (command-1), but without luck for both the iTunes official files (m4v) and the .mp4s. Any help is very appreciated.
Chris CA wrote:
Double click to play it then right click > Open in separate window.
Or you can set iTunes to always open movies in their own window.
iTunes prefs > Playback.
iTunes 10.5 (on 10.6.8) doesn't have a "playback in separate window" option.
Fortunately, the effectively hidden right-click "Playback Video in Separate Window" option is still available, and this choice holds for future videos.
I can keep my iTunes window on my left monitor and playback videos on my larger, widescreen middle monitor. -

thanks in advanceHi,
I am not sure why you are trying to convert the API packages into CAP files. The JAR files that ship with the JCDK are only stub implementations for compiling against. They do not have an actual implementation. You will find methods returning a short always return 0 etc. You should only need to convert your code into CAP files. You will just need to reference the .exp files that are included in the JCDK for the API so your code can be converted.
Cheers,

Hi everybody ,
I'm trying to build a javacard project by using ANT tool . The problem is when i use the JCOP tool converter (tric.jar) with JRE 1.4 or 1.5 i got the following error :
Error: class java.lang.RuntimeException, resolving constant-pool of clazz Lhun/eid/javacard/EIDApplet; failed: no such method getClass, ()Ljava/lang/Class; in Ljava/lang/Object;
and JCOP tool converter with JRE 1.6 , igot another error : invalid magic cafebabe
After that , i replaced the JCOP tool's converter by using the java_card_kit-2_2_2's converter , and i got another error :

Hi,
I'm trying to reproduce the APDU install (for load) and load (CAP file) commands the JCOP shell executes when you run an applet whith JCOP 3.1.
I noticed that the JCOP shell executes as many load commands as the CAP file size requires since the max datafield size of an APDU command is 255 bytes. But when I add the size of of the commands, I get 793 bytes when the CAP file size is 4695 bytes.
I found in the JavaCard JCVM specification, which describes the CAP file format that a CAP file is divided in several CAP files. So It seems to me that JCOP parse the "global" CAP file and only load parts of it in the emulated card.
The question is, which "little" CAP files are required to load the applet correctly and how could you know how the CAP file is actually structured in order to parse it correctly ?Hi,
the CAP-File is a special and very complex format and the result of the JCOP build process for a package (all applets of this package).
Loading an applet from a CAP-File via the JCShell "upload" command consists of 2 steps:
- first: send the upload initialization command
- second: send the code for this applet in (n) max. 255-byte blocks
Every code block has 6 leading command bytes.
The byte stream to send to the card or emulation depends on some requirements like header, code, debug-info, description...
So it cannot have the same size like your CAP-file!!
