Hi,All:



I tried to change cryptoflex e-gate 32k card’s PIN through APDU command…

According to the “Cryptoflex Cards Programmer’s Guild” , I send a command as follows:



CLA    INS    P1    P2    Send   Body(16)

F0      24     00    01     10     30303030303030303131313131313131



My source PIN is : 00000000

My destination PIN is : 11111111



Return Status always : 6D00 (Unknow command class value entered.)…

Does my command error ? and what is correct command in this case ?

Thanks All !!


Well, I have looked in the specification of GlobalPlatform 2.0.1' and GlobalPlatform 2.1.1 and no command for this purpose is defined, although they does support a Global PIN. But the documentation of my Giesecke & Devrient and also your documentation of the Cyberflex (It does, look at page 114 in the Programmers Guide) support this command

CLA     INS     P1      P2              Lc              Data
80/84   24      00      00/03–0F         00/08/10 (+)    PIN data

Le      Mode
—        —/S

This should work. Mode S means that you have to have established a secure channel. For the other parameters look into the doc.

Bye, Karsten
