* Use NK_get_status to implement Device::get_configRobin Krahl2020-02-03
| | | | | | | | | | | | libnitrokey’s NK_read_config function returns a pointer to an array that has been allocated using new[]. We would have to delete this pointer using delete[], but we only have access to free. Therefore this patch modifies the Device::get_config function to call NK_get_status instead of NK_read_config. This also makes the code more safe as we get the data as a struct instead of an array. It does not add much overhead as NK_read_config also executes the GET_STATUS command on the Nitrokey device.
* Implement From<&NK_status> for RawConfigRobin Krahl2020-02-03
| | | | | | This makes it easier to parse only the config part of the NK_status struct and avoids code duplication in the upcoming get_config refactoring.
* Implement std::convert::TryFrom<Config> for RawConfigRobin Krahl2019-12-27
| | | | | | Previously, the RawConfig struct had a try_from function. As the TryFrom trait has been stabilized with Rust 1.34.0, we can use it instead.
* Add license and copyright informationRobin Krahl2019-01-23
| | | | | | | This patch adds license and copyright information to all files to make nitrokey-rs compliant with the REUSE practices [0]. [0] https://reuse.software/practices/2.0/
* Refactor and clean up all codeRobin Krahl2019-01-23
| | | | | | | This includes: - using idiomatic Rust - limiting the scope of unsafe blocks - simplifying code
* Refactor library errors into LibraryError enumRobin Krahl2019-01-20
| | | | | | Previously, library errors were part of the CommandError enum. As command errors and library errors are two different error types, they should be split into two enums.
* Return Error instead of CommandErrorRobin Krahl2019-01-20
| | | | | | | | | | This patch changes all public functions to return the Error enum instead of the CommandError enum. This breaks the tests which will be fixed with the next patch. This patch also adds a placeholder variant Error::CommandError and a placeholder enum CommandError to make the transition to a new nitrokey-test version easier.
* Move util::CommandError to the new error moduleRobin Krahl2019-01-20
| | | | This prepares the refactoring of util::CommandError into multiple enums.
* Use the crate:: path qualifier for modulesRobin Krahl2018-12-16
| | | | | | This patch changes use declarations for modules within this crate to use the crate:: path qualifier. This will be mandatory in Rust edition 2018.
* Rewrap documentation comments to 100 charactersRobin Krahl2018-05-28

* Restructure code by functionalityRobin Krahl2018-05-22
In future versions, we want to support not only the Nitrokey Pro, but also the Nitrokey Storage. This requires a better code layout. This patch introduces two main changes: First, the OTP-specific methods are moved from the Device trait and the AdminAuthenticatedDevice struct to the functionality-based traits ConfigureOtp and GenerateOtp. This will hopefully make it easier to integrate the Nitrokey Storage. Secondly, the code is split into separate modules. These modules are currently all private and re-exported in the lib module, but we can consider making them public in the future.
