You can also have a look at the -[`nitrocli`][] crate, a command-line interface for Nitrokey devices that uses -this crate. - -## Compatibility - -This crate provides access to all features of the [`libnitrokey`][] C API for -both the Nitrokey Pro and the Nitrokey Storage: general configuration, one-time -password generation, the password safe and the secure storage on the Nitrokey -Storage. - -The required `libnitrokey` version is built from source. The host system -must provide `libhidapi-libusb0` (Linux) or `libhidapi` (non-Linux) in the -default library search path. Depending on your system, you might also have to -install the [Nitrokey udev rules][]. - -If you want to use a precompiled version of `libnitrokey`, you can set the -`USE_SYSTEM_LIBNITROKEY` environment variable during build. In this case, -`libnitrokey` must be available in the library search path. - -### Unsupported Functions - -The following functions provided by `libnitrokey` are deliberately not -supported by `nitrokey-rs`: - -- `NK_connect_with_ID`, `NK_list_devices_by_cpuID`. These functions can be - replaced by calls to `NK_connect_with_path` and `NK_list_devices`, which - also have a cleaner API. -- `NK_enable_firmware_update_pro`, `NK_change_firmware_password_pro`. These - functions execute commands that are not yet supported by the Nitrokey Pro - firmware. -- `NK_get_device_model`. We know which model we connected to, so we can - provide this information without calling `libnitrokey`. -- `NK_is_AES_supported`. This function is no longer needed for Nitrokey - devices with a recent firmware version. -- `NK_send_startup`. Currently, this function is redundant to `NK_get_time`. -- `NK_set_unencrypted_volume_rorw_pin_type_user`, - `NK_set_unencrypted_read_only`, `NK_set_unencrypted_read_write`. These - functions are only relevant for older firmware versions (pre-v0.51). As the - Nitrokey Storage firmware can be updated easily, we do not support these - outdated versions. -- `NK_totp_get_time`, `NK_status`. These functions are deprecated. -- `NK_read_HOTP_slot`. This function is only available for HOTP slots, not for - TOTP. We will support it once both types are supported by `libnitrokey`. -- All `*_as_string` functions that return string representations of data - returned by other functions. - -## Tests - -This crate has tests for different scenarios: Some tests require that no -Nitrokey device is connected, others require a Nitrokey Storage or a Nitrokey -Pro. We use the [`nitrokey-test`][] crate to select the test cases. You can -just run `cargo test` to auto-detect connected Nitrokey devices and to run the -appropriate tests. If you want to manually select the tests, set the -`NITROKEY_TEST_GROUP` environment variable to `nodev` (no device connected), -`pro` (Nitrokey Pro connected) or `storage` (Nitrokey Storage connected). - -Note that the tests assume that the device’s passwords are the factory defaults -(admin PIN `12345678`, user PIN `123456`, update password `12345678`) and that -an AES key has been built. Some tests will overwrite the data stored on the -Nitrokey device or perform a factory reset. Never execute the tests if you -don’t want to destroy all data on any connected Nitrokey device! - -The test suite contains some test that take very long to execute, for example -filling the SD card of a Nitrokey Storage with random data. These tests are -ignored per default. Use `cargo test -- --ignored` to execute the tests. - -## Acknowledgments - -Thanks to Nitrokey UG for providing two Nitrokey devices to support the -development of this crate.

Provides access to a Nitrokey device using the native libnitrokey API. -//! -//! # Usage -//! -//! Operations on the Nitrokey require different authentication levels. Some operations can be -//! performed without authentication, some require user access, and some require admin access. -//! This is modelled using the types [`User`][] and [`Admin`][]. -//! -//! You can only connect to one Nitrokey at a time. Use the global [`take`][] function to obtain -//! an reference to the [`Manager`][] singleton that keeps track of the connections. Then use the -//! [`connect`][] method to connect to any Nitrokey device. The method will return a -//! [`DeviceWrapper`][] that abstracts over the supported Nitrokey devices. You can also use -//! [`connect_model`][], [`connect_pro`][] or [`connect_storage`][] to connect to a specific -//! device. -//! -//! To get a list of all connected Nitrokey devices, use the [`list_devices`][] function. You can -//! then connect to one of the connected devices using the [`connect_path`][] function of the -//! `Manager` struct. -//! -//! You can call [`authenticate_user`][] or [`authenticate_admin`][] to get an authenticated device -//! that can perform operations that require authentication. You can use [`device`][] to go back -//! to the unauthenticated device. -//! -//! This makes sure that you can only execute a command if you have the required access rights. -//! Otherwise, your code will not compile. The only exception are the methods to generate one-time -//! passwords – [`get_hotp_code`][] and [`get_totp_code`][]. Depending on the stick configuration, -//! these operations are available without authentication or with user authentication. -//! -//! # Background operations -//! -//! Some commands may start background operations. During such an operation, every new command -//! will cause a [`WrongCrc`][] error. To check whether a background operation is currently -//! running, use the [`get_operation_status`][] method. -//! -//! Background operations are only available on the Nitrokey Storage. Currently, -//! [`fill_sd_card`][] is the only command that triggers a background operation. -//! -//! # Examples -//! -//! Connect to any Nitrokey and print its serial number: -//! -//! ```no_run -//! use nitrokey::Device; -//! # use nitrokey::Error; -//! -//! # fn try_main() -> Result<(), Error> { -//! let mut manager = nitrokey::take()?; -//! let device = manager.connect()?; -//! println!("{}", device.get_serial_number()?); -//! # Ok(()) -//! # } -//! ``` -//! -//!
