Java Card applet to test features and performance of a Hierarchical Deterministic Bitcoin Hardware Wallet implementation

Ledger Wallet Java Card Eligibility applet

This applet let you test the performance of your Java Card platform to run a Hierarchical Deterministic Bitcoin Hardware Wallet implementation.

It tries to find out all available algorithms, provide a pure Java implementation for the missing ones and gives a detailed report on support and performance.

If you have access to proprietary APIs, you can easily enable additional tests by providing an implementation of the ProprietaryAPI class
