    Problem in Creating DCF file

    Hi,
    I created .dcf and .drc file. I'm using 6230i to test the application. DCF file is loaded and displayed with lock image. But when i loaded drc file it's displaying the "File format not supported" instead of displaying the image which i encrypted in DCF file. The nokia toolkit generated .dcf and .drc file is working fine. Moreover the DCF file contains the padding as RFC2630. but this padding is not supporting in jce. so i used Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");

    could you anyone give me the solution
    reg,

    Hi ,
    How are you loading your drc file , that should be pushed throu a WAP gateway. In your Gateway you have to handle it seperately by using DATA_SM then your drc file will go as sms to your destination mobile.
    I believe you are working in bangalore me too.
    you can reach me at janvekar2004@rediffmail.com

    Re: Problem in Creating DCF file

    Hi,
    How are you generating drc and dcf files using NMIT or you are generating it programmatically. I see that you are using Java and generating the content. Did you succeed in forward lock and combined delivery generating the content using java.
    Regards

    Re: Problem in Creating DCF file

    Hi,
    i generated the dcf and drc files programatically. I can load the dcf file in 6230i and it's displaying with the lock image. That's fine. When i load the drc file which contains the rights to decrypt the content the error "file format not supported" is displaying. Due to this problem i couldn't do the further process. i'm unable to check the forward lock and combined delivery?

    Could you know how to crack that bug?

    Hi ,
    I think it might be a padding issue with jce, if possible use pkcs library.
    Hope this might be helpfull to you.

    I think you are not correctly creating the dcf file.
    What procedure you are following.
    are u adding the iV sequence infront of your encrypted content.
