JavaCard Hardware Wallet

Currently just a skeleton for the hardware wallet.

The .gpshell files are meant to be fed to GPShell. The statuswallet_install.gpshell file is actually dependent on the target hw. Currently it assumes that the default VISA AID and keys for the ISD are used, but the version number is 2.

The project is built using Gradle with the Fidesmo Javacard Gradle plugin. You can set the JavaCard HOME not only through the enviroment but also creating a gradle.properties file with the property "com.fidesmo.gradle.javacard.home" set to the correct path

Implementation notes

• This implementation will try to use only features available in JavaCard 2.2.2 for broader compatibility with existing hardware.
• The class byte of the APDU is not checked since there are nor conflicting INS code.
