This prepares the refactoring of util::CommandError into multiple enums.

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.

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.

We switched to rand::thread_rng() which cannot fail. Therefore the
CommandError::RngError is no longer needed and removed in this patch.

This patch changes use declarations for modules within this crate to use
the crate:: path qualifier. This will be mandatory in Rust edition
2018.

Most notably, for command errors, this will print a human-readable error
message instead of just the name of the enum.

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.
|

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 ?.

Previously, the Authenticate implementation for DeviceWrapper paniced if
the wrapped device is a Nitrokey Storage. This patch implements
authentication for wrapped Storage devices.
|
| |
|
|
|
| |
This patch adds the Storage struct and the test-storage feature. It
also enables all currently supported Pro commands for the Storage.
