Hello Folks.

I am trying to get my head around on how java applet loading works for sysmo-isim-sja2.

At first I used the following, updated example to compile a HelloSTK2.cap: https://github.com/mrlnc/HelloSTK2.git

This works fine and it also loads fine on sysmo-usim-sjs2 using shadysim.py

Now I want to load the exact same file to a sysmo-isim-sja2.

I tried with shadysim_isim.py from https://github.com/herlesupreeth/sim-tools:

---------------8<--------------- $ python shadysim_isim.py --pcsc 2 -l /home/owner/work/simcard_applet_loading/HelloSTK2.cap -i /home/owner/work/simcard_applet_loading/HelloSTK2.cap --enable-sim-toolkit --module-aid d07002ca44900101 --instance-aid d07002CA44900101 --nonvolatile-memory-required 0100 --volatile-memory-for-install 0100 --max-menu-entry-text 15 --max-menu-entries 05 --kic 56B6B26346DEF2A74BC8DFAF3BEA71D6 --kid 8EFE5A4B60C751FD18F33A24886967E7 Traceback (most recent call last): File "shadysim_isim.py", line 494, in <module> ac.load_app(args.load_app) File "shadysim_isim.py", line 369, in load_app self.load_aid_raw(aid, data, len(data) / 2) File "shadysim_isim.py", line 271, in load_aid_raw self.send_wrapped_apdu_checksw('80e60200' + ('%02x' % (len(data) / 2)) + data + '00c0000000') File "shadysim_isim.py", line 246, in send_wrapped_apdu_checksw raise RuntimeError("SW match failed! Expected %s and got %s." % (sw.lower(), response[1])) RuntimeError: SW match failed! Expected 9000 and got 6985. ---------------8<---------------

And I also tried with gp.jar from https://github.com/mrlnc/HelloSTK2.git ---------------8<--------------- $ java -jar ./gp.jar --key-enc 56B6B26346DEF2A74BC8DFAF3BEA71D6 --key-mac 8EFE5A4B60C751FD18F33A24886967E7 --key-dek 3BA47E883FE2462B5D43B85C4CCDF0AC --install /home/owner/work/simcard_applet_loading/HelloSTK2.cap [main] WARN pro.javacard.gp.PlaintextKeys - Don't know how to calculate KCV, defaulting to SCP02 [main] WARN pro.javacard.gp.PlaintextKeys - Don't know how to calculate KCV, defaulting to SCP02 [main] WARN pro.javacard.gp.PlaintextKeys - Don't know how to calculate KCV, defaulting to SCP02 [main] INFO pro.javacard.gp.GPSession - Using card master keys: ENC=56B6B26346DEF2A74BC8DFAF3BEA71D6 (KCV: 1ADB2F) MAC=8EFE5A4B60C751FD18F33A24886967E7 (KCV: 174546) DEK=3BA47E883FE2462B5D43B85C4CCDF0AC (KCV: D7011A) for null [main] INFO pro.javacard.gp.GPSession - Diversified card keys: ENC=56B6B26346DEF2A74BC8DFAF3BEA71D6 (KCV: 1ADB2F) MAC=8EFE5A4B60C751FD18F33A24886967E7 (KCV: 174546) DEK=3BA47E883FE2462B5D43B85C4CCDF0AC (KCV: D7011A) for SCP02 [main] INFO pro.javacard.gp.GPSession - Session keys: ENC=76900ED8B816F1822A29D7DC81F1B843 MAC=02D74CFFA5F85F1F999F23F60C22AF02 RMAC=87AFE7F26DDE69307EA35AE567AC8F26, card keys=ENC=56B6B26346DEF2A74BC8DFAF3BEA71D6 (KCV: 1ADB2F) MAC=8EFE5A4B60C751FD18F33A24886967E7 (KCV: 174546) DEK=3BA47E883FE2462B5D43B85C4CCDF0AC (KCV: D7011A) for SCP02 CAP loaded Error: INSTALL [for install and make selectable] failed: 0x6A80 (Wrong data/incorrect values in data) ---------------8<---------------

As it seems gp.jar seems to work better than shadysim_isim.py. Unfortunately I have no experience in java card programming yet, so its difficult for me to tell where the error could be.

(When I run gp.jar once more it tells me "Error: STRICT WARNING: Package with AID D07002CA44 is already present on card", I can also delete the applet again, so apparently its kind of loaded...)

Is there anyone here who managed to load an applet to a sysmo-isim-sja2 and how?

best regards. Philipp
