yubihsm.rs
Pure Rust client for YubiHSM 2 devices from Yubico.
About
This is a pure-Rust client library for YubiHSM 2 devices which implements most the functionality of the libyubihsm C library from Yubico's YubiHSM SDK. It provides two backends for communicating with YubiHSMs:
- HTTP: communicate with YubiHSM via the
yubihsm-connectorprocess from the Yubico SDK. - USB: communicate directly with the YubiHSM over USB using the rusb crate.
The yubihsm::Client type provides access to HSM commands.
This is NOT an official Yubico project and is in no way supported or endorsed by Yubico (although whoever runs their Twitter account thinks it's awesome).
NOTE: Looking for a YubiKey library instead of YubiHSM? Check out yubikey-piv.rs instead.
Minimum Supported Rust Version
This crate requires Rust 1.57 or newer.

|---|---|
| ✅ | Supported |
| ⚠️ | Partial/Untested Support |
| ⛔ | Unsupported |
NOTE: Commands marked ⚠️ have not been properly tested and may contain bugs or
not work at all. They are disabled by default: to use them you must enable the
untested cargo feature. If you do get them to work, please open an issue
(or PR) reporting success so we can promote them to ✅.
Testing
This crate allows you to run the integration test suite in three different ways:
- Live testing against a real YubiHSM2 device:
- via HTTP
- via USB
- simulated testing using MockHSM which implements some YubiHSM2 functionality
cargo test: test YubiHSM2 live over HTTP via yubihsm-connector
This mode assumes you have a YubiHSM2 hardware device, have downloaded the YubiHSM2 SDK for your platform, and are running a yubihsm-connector process listening on localhost on the default port of 12345.
The YubiHSM2 device should be in the default factory state. To reset it to this state, either use the yubihsm-shell reset command or press on the YubiHSM2 for 10 seconds immediately after inserting it.
You can confirm the tests are running live against the YubiHSM2 by the LED blinking rapidly for 1 second.
NOTE THAT THESE TESTS ARE DESTRUCTIVE: DO NOT RUN THEM AGAINST A YUBIHSM2 WHICH CONTAINS KEYS YOU CARE ABOUT
cargo test --features=usb: test YubiHSM2 live via USB
Adding the usb cargo feature builds in USB connector support in addition to
HTTP connector, and also runs the test suite live via USB rather than using
the yubihsm-connector process.
ALSO NOTE THAT THESE TESTS ARE DESTRUCTIVE: DO NOT RUN THEM AGAINST A YUBIHSM2 WHICH CONTAINS KEYS YOU CARE ABOUT
cargo test --features=mockhsm: simulated tests against a mock HSM
This mode is useful for when you don't have access to physical YubiHSM2 hardware, such as CI environments.
