Generic Trust Anchor API - Command Line Interface

Introduction

The repository provides a command line interface for the Generic Trust Anchor API. It exposes GTA API library functions to the command line and provides high-level use-case examples.

Dependencies

The CLI depends on GTA API Core and GTA API SW Provider.

Local build

• In the project root, initialize build system and build directory (like ./configure for automake):

$ meson setup <build_dir>

• Compile the code, the build directory is specified with the -C option:

$ ninja -C <build_dir>

• To install the following target can be used:

$ sudo ninja -C <build_dir> install

Using the CLI

The CLI reads the environment variable GTA_STATE_DIRECTORY and provides it to GTA API SW Provider to persist its state. If the environment variable GTA_STATE_DIRECTORY isn't set the default directory ./gta_state is used.

• gta-cli --help shows the parameters supported by the cli and how to run it
• gta-cli <FUNCTION> --help shows function specific help

Return code:

• returns EXIT_SUCCESS on success
• returns EXIT_FAILURE in case of error
