How to create file with APDU

Hello everybody,
It's my first time using Java Card ^_^,I want to create a file and fill the fill with binary data.but i don't know how to create file with APDU commands,so I need help here.
I think that there must be a Manual of the JavaCard's OS in this world,can someone tell me where to download it??
Thanks.
the fllowing is my card:
Samsung S1
Model:TiEx-32J
EEPROM size:32k
Platform Version:OP 2.0.1
Card Manager Status:OP_READY
KMC:40~4F/No derivation

If you look around the forum for a bit, you will see that there is no notion of file systems on JavaCards (lexdabear posted this information less than two hours ago :-)). To store files, you will have to write an applet to hold byte arrays of the required size and handle receiving and sending of these.
As for documentation, you should have a look at the GP (General Platform) specification at http://www.globalplatform.org/, which defines communication between smart cards and other devices, as well as Sun's own JavaCard pages (http://java.sun.com/products/javacard/), which contain several useful resources on JavaCards.

"GemSafeXpresso Card returns "6D 00" for most of APDU commands"

Hi everyone,
I am confused with GemSafeXpresso smart card, GemSafeXpresso card can be authenticate with CardManager but I can not delete the instance of applet with GlobalPlatform Delete APDU command,it returns "6D 00"
In following you can find what was happend on my card:
At first,I installed GemSafe V2.04 applet that is placed on Rom of the card,I mean I created an instance of GemSafe applet with "A0 00 00 00 18 0A 00 00 01 63 42 00" ID successfully, after that I selectd GemSafe applet and Root and then I created some EFs under root ,but now I can not delete the instance of applet that I have created,The card returns "6D 00" ,I can authenticate with CardManager but I can not delete , create or install ,...
I should say ,at first I installed and deleted the instance some times but I can not do now ,I would like to know what is the reason of this problem.
I appreciate for any help,
Yours sincerely,
Orchid

Dear lexdabear,
Thanks a lot for your reply,
Gemalto has written GemSafe applet and has loaded on Rom of GemSafeXpresso card but I can just install it and make an instance of it on the card ,So I don not have source of applet.
In following you can find the APDU command for install ,delete ,...

Issuing apdu commands

I am experiencing problems running the demos that come with the java card kit such as the wallet and javapurse. i am able to run the apdutool utility with the the specified script file as input without any problems. But does it just end there? I thought it was possible for me to key in specific commands for crediting or debiting electronic cash in the wallet applet, for example. My question is-once I generate the output file, how do i proceeed from there - so that finally i can be able to send specific apdu commands to the sample applets. I would appreciate help soon so that i can be able to apply in a project i am undertaking.

Understanding the Delete Applet APDU

Hello all,
I'm trying to understand each byte of the delete APDU command.
I'm using this guide as a reference: http://askra.de/software/jcdocs/kit-user-2.2.1/cJDKinstaller.html#wp8960
My delete command is the following:
80 C4 01 00 08 07 (AID - 7 sets)
Is this understanding correct? When I run the command after selecting the applet, I receive a 6D00 response, stating the command structure is not supported.
Thanks,
Collin

I see you said: When I run the command after selecting the applet, I receive a 6D00 response, stating the command structure is not supported.
you must select the security domain/cardmanager, then send the delete command

'Get Response' APDU command in a script for apdutool

Dear all,
I'm facing some problems with apdutool (javacard 2.2.2 distribution) in executing the 'Get Response' command.
In fact its syntax differs from the one specified for other APDU commands accepted by apdutool, as Lc is replaced by the expected response lenght, i.e. by Le.
I tried inserting a fake P3 (Lc), but I always get ParseException errors.
All previous commands in the script are properly executed, including the one for which the subsequent 'Get Response' is tried. In particular, the SW2 byte returned by the latter command contains the right expected length.
I'm working with T0 algorithm and non-extended mode is specified in the APDU script.
Thank you very much to anyone who could help.
Best regards
Marco

Hi,
You could ensure that both of the text fields are not empty on your 'dashboard' before executing the FS00 tcode. This would negate the popup from ever appearing.
To do this you can use the "IF <text field control ID> Is Empty" statement in your script and then output a custom error message to another text box if the condition is true. then use an "IF <text field control ID> Is NOT Empty" statement to copy the value/s execute the FS00 tcode if the condition is true.
Now if you're going to check multiple fields for entries before executing the FS00 you'll have to get a little more creative and do something like I did in one my scripts (thanks again to Steve Rumsby for the tips) and create a 'check field' where you can enter values for items checked successfully and then use a little bit of javascript to count up the checks and check the result before executing the next part of the script.
Another idea is to check for the existence of the popup and navigate past it in your script, to do this you can use the "IF <control ID> control exists" statement.
Either one should work.

Command APDU is not written in your source code, rather it is sent from PC or programmed Card Acceptance Device/ Card Reader/ Terminal.
The code installed in the Java Card should be able to handle the Command APDU received and process it accordingly, and finally your code should be able to send out response APDU.
You may think your code as a decoder, to retrieve each byte (CLA, INS, P1, P2, DATA, LC) using the Java Card API, you should be able to do it.
Also, I notice in your code that you want to work out with strings, but Java Card does not support strings, chars, long, float, double ...
to send out reponse APDU, there are certain steps that you can use, not just simply print like ordinary J2SE may use.
hope this will help u

What is the data associated with the APDU commands

hi,
Please guide me on what data should be associated with the command APDU.
for eg. we send 00 a4 04 00 for the select command followed by the AID.
Similarly what should be sent as a data (eg. AID in case of SELECT) with following APDU commands::::
LOAD,, InItUPDATE,, External Authentication,, Install
regards,,
PhadkeA

I have the book Javacard technology for smartcards by Zhiqun Chen so
I" ll try to help you. About the install command it's syntax is:
install(byte[] bArray,short bOffset,byte bLength)
The bArray contains the installation parameters, but from what I read in
the book they are optional. From the example of the book it seems
that generally they are some initialization values for the variables of
the applet.
I didn't find any info about the other commands that you mention.Sorry!

Creating an applet instance

Hi
I am using Schulmberger Smart Card Tool Kit in order to create applet and applet instances.
I have created the applet inside the card but I couldn't create an applet instance. Because when I am going to create the applet instance by using the software it asks the install parameters. Still I don't know does it ask the parameters to call the method
// Install method
     public static void install(byte buffer[],short offset,byte length){
     // create a CryptoTest applet instance
     new CryptoTest(buffer, offset, length);
     } // end of install method
How should I give such parameters. Please reply me soon
If you can give me an example, That is perfect
Thanks
Best regards
Denzil jayasinghe
gayandenzil@gmail,com

Normally installation parameters are just passed to the Applet itself. It can evaluate it in the install method. The system specific parameters may be used by the OS to set minimum memory limits. What install parameters are required by your smart card OS, you should find in the data sheet or contact Gemalto customer support (Schlumberger --> Axalto --> Gemalto).
For reference check GP 2.1.1 card specification, 9.5 INSTALL Command, 9.5.2.3.6 INSTALL [for load] and INSTALL [for install] Parameters, Table 9-36: Install Parameter Tags

Subsembly create file with apdu

I read in manual to create file, and it only said that i have to use
E0, for other arguments it didnt say nothing... so what do i put for
p1, p2 and cla nad send data?
I used just size and i got this back:
SW1:6B
SW2:00
It means that p1 or p2 is invalid! So what should i do? help

Apdu command length

Hi
I want to get the length of the entire command in my applet.
I want to know "5" for the following example.
/send 8084000000
Is there such API?

a command parser in process method can be something like that:
byte MY_CLA = (byte)0x80;
byte MY_INS = (byte)0x84;
// get the APDU buffer bytes (get header first)
byte[] apduBuffer = apdu.getBuffer();
// Checking CLA values
switch(apduBuffer[ISO7816.OFFSET_CLA]){
case MY_CLA:
    // For a given CLA value, checking INS values
    switch(apduBuffer[ISO7816.OFFSET_INS]){
      case MY_INS:
        // For a given INS value, checking P1, P2, P3 for example:
        if((apduBuffer[ISO7816.OFFSET_P1] != (byte)0x00) || (apduBuffer[ISO7816.OFFSET_P2] != (byte)0x00))
           ISOException.throwIt(ISO7816.SW_INCORRECT_P1P2);
        if(apduBuffer[ISO7816.OFFSET_LC] != (byte)0x08)
           ISOException.throwIt(ISO7816.SW_WRONG_LENGTH);
        // After the command format checking, i can continue the processing that my command is supposed to do
      break;
      default:
        // Throw iso exception: bad instruction byte value
        ISOException.throwIt(ISO7816.SW_INS_NOT_SUPPORTED);
      break;
break;
default:
    // Throw iso exception: bad class byte value
    ISOException.throwIt(ISO7816.SW_CLA_NOT_SUPPORTED);
break;
}This example is for a case 3 apdu command.
If your command is a case 2, you will need to get Le by invoking setOutgoing() method and checking the expected value of Le.

APDU command chaining

Hello, I am sending some byte array by portions of 255 bytes to my on-card Applet using a sequence of APDU command-response operations. I just wanted to know, in case there is any possibility to make on-side chaining: send some sequence of APDU commands and receive only one response from the applet after the last portion of data received.
Best regards,
Eve

According to ISO 7816-4 the chaining possibilities are
- Extended APDU --> up to 65k data field
- Command chaining --> ICCD responds after each APDU
Your requirement would fit only to extended APDU. Java Card adopts only a certain class of the APDU structure from ISO 7816-4, which does not allow extended APDU: JC 2.2.1 API, javacard.framework.APDU (p. 44) ..
This class does not support extended length fields.
..This is one of the reasons it won't work with a card compliant to Java Card. The other reason are the fixed constants for the ISO7816 interface (e.g. javacard.framework.ISO7816.OFFSET_CDATA, which is 5 --> extended length field not possible).

APDU commands for Globalplatform card

Hi,
I'm trying to develop embedded software that talks to a Oberthur Cosmo 64 card via low level APDU commands. I've looked at the Globalplatform 2.1.1 specs as well as the cosmo 64 technical brief, but it seems that there are only a few APDU commands. I've only worked with native cards before this, and native cards seem to have a lot more commands. For example, I can't even find a "Get Challenge" command nor any kind of authentication/key generation/pin verification commands.
Would like to know how I can get started just sending simple APDU commands for key generation, challenge-response, authentication, etc?

Well I only see 10 commands under Part IV(APDU Command Reference) of the GPP 2.1.1 specs.
However when I see Appendix D I realize there's actually an initialize update and external authenticate APDU command, neither of which are found in Part IV.Yes, the commands for secure channel protocol are located in the Appendices. One can argue if this commands should be listed in APDU Command Reference, but GP Committee wanted to make is as flexible as possible in case another SCP is added, with different commands.
From what I've read so far in Appendices D/E, it seems that the difference is that
1) SCP01 supports mutual auth while for SCP02, only the card auths the host, with an option for the reverse.
2) For SCP01, card ensures host is genuine, but no mention of the reverse to be true. For SCP02, both host and card must be ensured to be genuine.
3) For SCP01, data from host to card is not susceptible to sniffing(encryption?), but no mention of the reverse to be true. For SCP02, both directions are not susceptible to sniffing.You are referencing the R-MAC option. It is only present in SCP02. There is no encryption from the card side (smthg like R-ENCRYPTION), you would need to handle this in your Applet. Be aware that R-MAC is optional, depending on the security policy of the issuer. For example in JCOP, only C-MAC and C-DECRYPTION is supported. Another differences between SCP01 and SCP02:
- The DEK in SCP02 is a session key, and in SCP01 it is static
- The INITIALIZE UPDATE command is different regarding the P2 parameter and the structure of the response
In the latest version of GP 2.2 SCP01 is deprecated.
Seems like other than the initial authentication, SCP02 is always more secure than SCP01?I would only conclude this if R-MAC is supported in SCP02.
Also, where can I find Java Card 2.2.1/2.2.2 specs? I'm not interested in using the API since I'm developing embedded firmware, so I need to talk to the card directly via APDU commands.http://java.sun.com/products/javacard/specs.html

APDU Commands - How they work ?

Hi,
Iam all new to the JavaCard programming and wanted to understand some basics. The APDU Commands (CLA, INS, P1, P2, ...) are they reserved commands (as in reserved words). If so, how do I get a listing of the same.
Eg. I am looking into one of the programs which have the following few lines,
SetLength(DataToSend, 13);
DataToSend[0] := $88;
DataToSend[1] := $10;
DataToSend[2] := $11;
DataToSend[3] := $00;
DataToSend[4] := $08;
DataToSend[5] := $F9;
DataToSend[6] := $FD;
DataToSend[7] := $CE;
DataToSend[8] := $8B;
DataToSend[9] := $F6;
DataToSend[10] := $F4;
DataToSend[11] := $14;
DataToSend[12] := $E0;
FSCard.SendCustomAPDU(DataToSend, ReceiveBuffer);
I believe the above writes info. to the card.
If Yes, how do I retrive the same from Card?
If No, then what does the instruction stand for?
Appreciate your help ....

hI,
Iam trying to write a sample code by trying to write data to card using XOR, converting the same back in the applet to the original string and retriving the same. The return value is still in XOR value and not the original i sent. Please let me know what iam doing wrong here?

Creating Job definition using Command line.

Hi all,
is there a possibility to create a job through command line, with parameter as CMD and source as any batch file and scheduling it on the fly.
Let me know...
Always
sai.

yes, you can use ldapmodify to add objectclasses. You should modify cn=schema and follow the objectclasses and attributes syntax. You can check config/schema directory in any dsee instance for examples.
Other way is adding objectclasses editing directly 99user.ldif schema file whereas dsee is down.
