Question about application privileges

Post by Danieken » Thu Dec 03, 2015 4:05 am

In INSTALL [ for install ] command, application privileges can be set to 1 byte or 3 bytes. But now the tools I am using, such as JCOP/pyApduTool/GlobalPlatform library/pyGlobalPlatform library, all limits the application privileges to 1byte. Why? When can we use the other two bytes?

GlobalPlatform Card Specification 2.1.1:
Application Privileges are coded on one byte ...

GlobalPlatform Card Specification 2.2.1:
Privileges are coded on three bytes ...

For GP compatibility, the privileges is coded on one byte.

The GlobalPlatform/pyGlobalPlatform is implementation of GP211, so the privileges is coded on one byte.
sense and simplicity
