Hi,
I have coded a Java card applet.
It doesn't contain any OP code. It is coded using JCDK only !
I'm trying to apply OP commands like Initialize Update,
External Authenticate to it, from Host Application .
Can somebody tell me, is it possible to apply OP commands to such an
applet ?
I've become successful in selecting Card Manager,
for Initialize Update it returns 90 00, however for External
Authenticate it returns 63 00.
I'm not using OpenSecureChannel() or verifyExternalAuthenticate()
methods of ProviderSecurityDomain,
I've formed Command APDUs from byte arrays.
Can somebody help me out ?
Following is host application code,
