* Move util::CommandError to the new error moduleRobin Krahl2019-01-20
| | | | This prepares the refactoring of util::CommandError into multiple enums.
* Pass temporary password as *const c_charRobin Krahl2019-01-20
| | | | | | | | | The random number generator used for the temporary password produces a Vec<u8>. The libnitrokey functions using the temporary password require a pointer to a c_char. Previously, we cast the u8 pointer to the Vec<u8> to a i8 pointer (unsigned to signed). This leads to a type mismatch if the char type is not signed. Therefore we now cast to c_char instead of i8.
* 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.
* 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.
* Fix formatting using to rustfmtRobin Krahl2018-12-30

* 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.
* Use {} instead of {:?} where possibleRobin Krahl2018-06-07
| | | | | Most notably, for command errors, this will print a human-readable error message instead of just the name of the enum.
* Implement easier CString creationRobin Krahl2018-06-07
| | | | | | The new get_cstring method in util returns a Result<CString, CommandError>, so mast callers can just use the ? operator to unwrap the result instead of cumbersome unwrapping code.
* Use Result<(), CommandError> instead of CommandStatusRobin Krahl2018-06-07
| | | | | | The Result enum is more idiomatic and easier to use than our custom CommandStatus enum with the same structure. This is especially true for the try operator ?.
* Fix formatting issuesRobin Krahl2018-05-31

* Fix implementation of Authenticate for DeviceWrapperRobin Krahl2018-05-29
| | | | | | Previously, the Authenticate implementation for DeviceWrapper paniced if the wrapped device is a Nitrokey Storage. This patch implements authentication for wrapped Storage devices.
* Add rudimentary support for the Nitrokey StorageRobin Krahl2018-05-29
| | | | | This patch adds the Storage struct and the test-storage feature. It also enables all currently supported Pro commands for the Storage.
* Move Admin, User and Authenticate to auth moduleRobin Krahl2018-05-28
