* pws: Interpret empty strings as unprogrammed slotsRobin Krahl2019-01-16
| | | | | | | | | | | | Until the last commit, all empty strings returned by the library were interepreted as errors. As the PWS functions return empty strings for unprogrammed slots, the methods to access the PWS data returned an error when querying a slot that is not programmed. Since the last commit, they return an empty string instead. This patch restores the old behavior by returning an error instead of an empty string. Yet we change the error variant: SlotNotProgrammed instead of Undefined.
* Fix result_from_string for empty return valuesRobin Krahl2019-01-16
| | | | | | | | | | | An empty string returned from a libnitrokey function can either indicate an error or be a valid return value. Previously, we assumed that it indicates an error. But instead, we should check the last command status and use it to decide whether to return the empty string or an error code. This breaks the unit tests that assume that empty strings cause errors. These will be fixed in the next patches.

* Use rand_os for random data generationDaniel Mueller2019-01-14
| | | | | | | | | | | | The rand crate comes with a slew of dependencies to cover all sort of randomness related tasks in various scenarios. However, this crate really only requires a tiny subset of this functionality. As it turns out, this core functionality is provided by the rand_os crate. This change drops the dependency to rand in favor of rand_os. In order to accomplish that, it brings back the RngError variant for the CommandError enum to capture the possibility of the creation of the random number generator failing.
* Add the clear_new_sd_card_warning method to StorageRobin Krahl2019-01-14
| | | | | | The clear_new_sd_card_warning method calls the libnitrokey NK_clear_new_sd_card_warning function to reset the corresponding flag in the Storage status.
* Add the get_production_info method to the Storage structRobin Krahl2019-01-14
| | | | | | | | | | | The get_production_info method maps to the NK_get_production_info function of libnitrokey. The Storage firmware supports two query modes: with or without a write test. libnitrokey only performs the query without write test, so the fields that are only set for the write test are ignored in our implementation. This affects: - user and admin retry counts - smart card ID - SD card size

* Add export_firmware to the change logRobin Krahl2019-01-12
|
* Add export_firmware method to StorageRobin Krahl2019-01-12
| | | | | | | The export_firmware method writes the firmware of the Nitrokey Storage to the unencrypted storage. We only test that the command succeeds as mounting the unencrypted storage and accessing the file is out of scope for the tests.
* Document unsupported outdated functionsRobin Krahl2019-01-12
| | | | | | | | | | We do not support old firmware versions on the Nitrokey Storage, so we document that these outdated functions are not supported: - NK_set_unencrypted_volume_rorw_pin_type_user - NK_set_unencrypted_read_only - NK_set_unencrypted_read_write - NK_set_encrypted_read_only - NK_set_encrypted_read_write
* Add set_unencrypted_volume_mode to StorageRobin Krahl2019-01-12
| | | | | | | | | | The new set_unencrypted_volume_mode method sets the access mode of the unencrypted volume on the Nitrokey Storage. Depending on the requested access mode, it calls either NK_set_unencrypted_read_only_admin or NK_set_unencrypted_read_write_admin. Note that this function requires firmware version 0.51 or later. (Earlier firmware versions used the user PIN.)
* Introduce VolumeMode enum in deviceRobin Krahl2019-01-12
| | | | | | The VolumeMode enum will be used when setting the access mode for the unencrypted volume. It can also be used when refactoring the VolumeStatus enum in a future release.
* Move the update PIN from tests/util to tests/deviceRobin Krahl2019-01-12
| | | | | | The update PIN is only used in the Storage tests, so it is moved from the common tests/util module to the tests/device module. This fixes compiler warnings when compiling the other test modules.

* Update readme and todo for NK_get_device_modelRobin Krahl2019-01-11

* Add the wink method to the Storage structRobin Krahl2019-01-11
| | | | | | This patch adds the wink method to the Storage struct that lets the Nitrokey device blink until reconnected. We do not test this method as it does not change the state that we can observe.
* Add the get_library_version functionRobin Krahl2019-01-11
| | | | | | | This patch adds the get_library_version function to the main library module that queries and returns the libnitrokey version. As the version fields are static values, we fetch them all at the same time and do not provide getters for the individual fields.
* Check InvalidHexString error in otp test suiteRobin Krahl2019-01-09
|
* Fix otp::totp_error test caseRobin Krahl2019-01-09
| | | | | Previously the totp_error test case in the otp test suite called hotp methods. This patch fixes the test case by calling totp metods instead.
* Do not check for errors in connect testsDaniel Mueller2019-01-09
| | | | | | | | | The connect_* device tests fail when run in a setup with a Pro and Storage stick present. The problem is that these tests assume only one stick to be present, and that the corresponding connect function for the other stick reports an error. However, in a two stick setup there is no such guarantee. This patch removes tests for those assumptions.
* Make three more error codes knownDaniel Mueller2019-01-09
| | | | | | | | | | | | | Three more error codes are defined in libnitrokey but currently reported as the CommandError::Unknown variant: 200: representing a string that exceeds a limit 202: indicating a string that is not in hexadecimal format when it should be 203: suggesting that the target buffer is smaller than the source buffer and, hence, too small This change introduces the CommandError variants StringTooLong, InvalidHexString and TargetBufferTooSmall, respectively, representing those errors.
* Release v0.3.1v0.3.1Robin Krahl2019-01-07

* Add the connect_model functionRobin Krahl2019-01-07
| | | | | | This patch adds the global connect_model function that can be used to connect to a Nitrokey device of a given model. Contrary to Pro::connect and Storage::connect, the model does not have to be set at compile time.
* Rename device::connect_model to device::connect_enumRobin Krahl2019-01-07
| | | | connect_model will be used for a public function with the next patch.
* Document the Undefined error for the connect methodsRobin Krahl2019-01-07
|
* Add support for the hidden volumes on a Nitrokey StorageRobin Krahl2019-01-06
| | | | | | | | | | This patch introduces the methods enable_hidden_volume, disable_hidden_volume and create_hidden_volume for the Storage struct to support the hidden volumes on the Nitrokey Storage. The enable and create methods require that the encrypted storage has been enabled. Contrary to authentication and password safe access, we do not enforce this requirement in the API as file system operations could have unwanted side effects and should not performed implicitly.

* Prefer assert_eq over is_ok() checksDaniel Mueller2019-01-05
| | | | | | | | | | We experienced various problems running the tests and while they may or may not be caused by local setup issues, it is helpful to have more information than just an indication that an assertion (true/false) was violated. To that end, this change adjusts some of the assert!(<func>().is_ok()) to compare against Ok(()) instead. This way, if the result is not the Ok variant, the error code will get printed.
* Adjust PWS tests to use nitrokey-test crateDaniel Mueller2019-01-05

* Use nitrokey-test for nitrokey device testsDaniel Mueller2019-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is the first in a series to migrate the existing tests to using the nitrokey-test crate. The crate provides a couple of benefits over the existing way testing works: - test execution is automatically serialized (i.e., no more need for --test-threads) - available devices are detected at runtime (i.e., no more need for --features test-pro) - tests capable of running only on a specific device are automatically skipped if this device is not present In addition to that, the crate also offers selection of particular groups of tests by virtue of the NITROKEY_TEST_GROUP environment variable. If set (valid values are "nodev", "pro", and "storage") only tests of the particular group are run (those tests will fail if a required precondition is not met, i.e., if a device is present but "nodev" is set, or if the "pro" group is run but no device or a storage device is present). Unfortunately, it has some limitations as well. Most importantly Rust does not allow us to indicate whether a test has been skipped or not. While it has #[ignore] support, that strictly is a compile-time feature and, hence, not usable. This patch in particular pulls in the nitrokey-test crate and adjusts the existing device tests to make use of it.

* Update documentation and test for factory_resetRobin Krahl2019-01-04
| | | | | | Contrary to my previous beliefs, build_aes_key has to be called even after a factory reset using the Nitrokey API. This patch updates the documentation and the unit tests based on this insight.
* Fix documentation test for Storage::change_update_pinRobin Krahl2019-01-04
|
* Add Storage::enable_firmware_update methodRobin Krahl2019-01-03
| | | | | | | | This patch adds the enable_firmware_update method to the Storage struct that uses NK_enable_firmware_update to put the Nitrokey Storage into update mode. This method is not tested as external tooling is required to resume normal operation and as it is hard to bail out if an error occurs.
* Add Device::build_aes_key methodRobin Krahl2019-01-03
| | | | | | | | This patch adds the build_aes_key method to the Device trait that uses the NK_build_aes_key function to build new AES keys on the device. This effectively resets the password safe and the encrypted storage. It is unclear whether other data (e. g. the one-time passwords) are affected too.
* Add Device::factory_reset methodRobin Krahl2019-01-03
| | | | | | | This patch adds the factory_reset_method to the Device trait that uses the NK_factory_reset function to perform a factory reset. The tests verify that the user and admin PIN are reset and that the OTP storage and the password safe are deleted.
* Add Storage::change_update_pin methodRobin Krahl2019-01-03
| | | | | | This patch adds the change_update_pin method to the Storage struct that uses the NK_change_update_password function to set the password required for firmware updates.
* Document decryption failure for get_password_safeRobin Krahl2019-01-03
| | | | | | After a factory reset, the password safe cannot be accessed as its secret cannot be decrypted. This patch improves the documentation for GetPasswordSafe::get_password_safe to reflect this behavior.

* Preserve unknown error code valuesDaniel Mueller2019-01-03
| | | | | | | | | | The CommandError::Unknown variant, which is used whenever a reported error code is not known, makes it close to impossible to determine the root cause of, say, a one-off error, because all information explaining what went wrong is discarded. With this change we adjust the Unknown variant to include the error report. In addition, we introduce a new CommandError variant, Undefined, that is used when no error code is available.
* Fix typo: occured -> occurredDaniel Mueller2019-01-03

* Extend unlock_user_pin testsRobin Krahl2019-01-03
| | | | | | This patch adds a test case that changes the PIN when calling unlock_user_pin. The previous test case only unlocked the current user PIN.
* Remove CommandError::RngErrorRobin Krahl2019-01-03
| | | | | We switched to rand::thread_rng() which cannot fail. Therefore the CommandError::RngError is no longer needed and removed in this patch.
* Add force argument to ConfigureOtp::set_timeRobin Krahl2019-01-02
| | | | | | | | This patch adds the force argument to the set_time method in the ConfigureOtp trait that allows the user to choose whether jumps to the past are allowed when updating the time. It is implemented by using the NK_totp_set_time_soft function. Previously, jumps where unconditionally allowed.
