# Keymaster Benchmark

The Keymaster Benchmark is a standalone tool for measuring the performance of keymaster implementations.

## Building

Build:
`m  keymaster_benchmark`

Transfer to device/emulator:
`adb sync data`

The benchmark executable should will be located at `data/benchmarktest/keymaster_benchmark/keymaster_benchmark` on the device.

## Usage

Keymaster Benchmark is built on [Google microbenchmark library](https://github.com/google/benchmark).
All of the commandline arguments provided by the microbenchmark library are valid, such as `--benchmark_filter=<regex>` or `benchmark_out_format={json|console|csv}`.
In addition to the command line arguments provided by microbenchmark, `--service_name=<service_name>` is provided allow specification of the keymaster service name, e.g. specify `--service_name=strongbox` to benchmark strongbox.
