# A Rust library for interacting with CTAP1/CTAP2 Security Keys
|
||
|
|
|
||
|
|
[](https://travis-ci.org/mozilla/authenticator-rs)
|
||
|
|
|
||
|
|
|
||
|
|
This is a cross-platform library for interacting with Security Key-type devices via Rust.
|
||
|
|
|
||
|
|
* **Supported Platforms**: Windows, Linux, FreeBSD, and macOS.
|
||
|
|
* **Supported Transports**: USB HID.
|
||
|
|
* **Supported Protocols**: [FIDO U2F over USB](https://fidoalliance.org/specs/fido-u2f-v1.1-id-20160915/fido-u2f-raw-message-formats-v1.1-id-20160915.html). [CTAP2 support](https://fidoalliance.org/specs/fido-v2.0-ps-20190130/fido-client-to-authenticator-protocol-v2.0-ps-20190130.html) is forthcoming, with work being done in the **unstable** [`ctap2` branch](https://github.com/mozilla/authenticator-rs/tree/ctap2).
|
||
|
|
|
||
|
|
This library currently focuses on USB security keys, but is expected to be extended to
|
||
|
|
support additional transports.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
There's only a simple example function that tries to register and sign right now. It uses
|
||
|
|
[env_logger](http://rust-lang-nursery.github.io/log/env_logger/) for logging, which you
|
||
|
|
configure with the `RUST_LOG` environment variable:
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo build --example main
|
||
|
|
RUST_LOG=debug cargo run --example main
|
||
|
|
```
|
||
|
|
|
||
|
|
Proper usage should be to call into this library from something else - e.g., Firefox. There are
|
||
|
|
some [C headers exposed for the purpose](authenticator/blob/master/src/u2fhid-capi.h).
|
||
|
|
|
||
|
|
## Tests
|
||
|
|
|
||
|
|
There are some tests of the cross-platform runloop logic and the protocol decoder:
|
||
|
|
|
||
|
|
```
|
||
|
|
cargo test
|
||
|
|
```
|
||
|
|
|
||
|
|
## Fuzzing
|
||
|
|
|
||
|
|
There are fuzzers for the USB protocol reader, basically fuzzing inputs from the HID layer.
|
||
|
|
There are not (yet) fuzzers for the C API used by callers (such as Gecko).
|
||
|
|
|
||
|
|
To fuzz, you will need cargo-fuzz (the latest version from GitHub) as well as Rust Nightly.
|
||
|
|
|
||
|
|
```
|
||
|
|
rustup install nightly
|
||
|
|
cargo install --git https://github.com/rust-fuzz/cargo-fuzz/
|
||
|
|
|
||
|
|
cargo +nightly fuzz run u2f_read -- -max_len=512
|
||
|
|
cargo +nightly fuzz run u2f_read_write -- -max_len=512
|
||
|
|
```
