Code

The target app must be written in Java for smartcards conforming to at least GlobalPlatform 2.1.1.

Card-specific constants and code must 'live' in a dedicated class. Stubs for such class can be generated automatically from AlgTest results (or a to-be-written dedicated app).

In the written code, readability should be preferred over optimization for performance: slowness comes from public key operations (handled by coprocessor). Better readability makes code review easier and bugs can be found faster.
