This patch adds the fill command that overwrites the SD card with random
data. Similar to the reset command, we always require the user to enter
the admin PIN even if is cached.

The Storage device keeps track of the areas of the SD card that have
been written to during this power cycle. This data can be accessed using
the NK_get_SD_usage_data function that returns a range of the SD card
that has not been written. This data can be used as a guide line when
creating new hidden volumes.
This patch adds the SD card usage data to the output of the status
command for Nitrokey Storage devices.

For consistency with the --usb-path option, this path renames the device
path column in the output of the list command to USB path.

This patch adds the --usb-path option as an additional way to filter the
Nitrokey device to connect to. While the serial number is a better
identifier in theory, the Nitrokey Storage devices do not send their
serial number in the USB device descriptor. Having the --usb-path
options allows users to select one of multiple Nitrokey Storage devices.
While we could directly call the nitrokey::Manager::connect_path
function with the specified path, we integrate the --usb-path option
into the existing find_device function for consistent error messages and
to avoid having to duplicate the --model and --serial-number checks.

This patch adds test cases for the new connection logic:
- connect_multiple checks that nitrocli aborts if more than one Nitrokey
device is connected and no filter is set.
- connect_serial_number checks that we can use the --serial-number
option to connect to all supported Nitrokey devices.
- connect_wrong_serial_number checks that nitrocli aborts if it can’t
find a device with the requested serial number.
- connect_model checks that we can use the --model option to select the
Nitrokey device to connect to, and that nitrocli aborts if it finds no
matching device or multiple matching devices.

This patch introduces two new functions, find_device and connect, to
connect to a Nitrokey device. find_device queries the attached Nitrokey
devices, applies the filters (currently only the --model option) and
returns the first match. connect calls find_device and connects to the
returned device.
This refactoring allows us to add more device filters, for example a
--serial-number option, without code duplication.

In the future we would like to provide more ways for tests to create a
Nitrocli instance. In order to prevent explosion of with_XXX methods for
each possible combination of arguments, this change allows for an easier
configuration of an existing object with builder-pattern-inspired
modifier methods.

While the Nitrocli::model() method was well intentioned, we do not
actually need it because we create a Nitrocli instance from the model
passed to the individual test. We can just reuse this model instead.
With this patch we do exactly that, allowing us to get rid of
Nitrocli::model() all together.

With this change we switch to using a REUSE compliant way of specifying
the copyright & license of the program. To be fully in conformance we
also add additional license specifications for the remaining files in
the project. Lastly, a new CI pipeline rule takes care of verifying
compliance on an ongoing basis.
|
| |
|
|
|

This change adjusts the copyright header in all files to no longer
mention individuals but refer to The Nitrocli Developers in general.

Since we moved the model, no_cache and verbosity fields from ExecCtx
into Config and added a Config field to both ExecCtx and RunCtx, RunCtx
and ExecCtx are identical. Therefore this patch merges the ExecCtx and
RunCtx structs into the new Context struct.

This patch adds a simple configuration file that demonstrates the syntax
and contains some documentation. We suggest to ship this file together
with nitrocli and to install it e.g., in the /usr/share/doc/nitrocli
directory. This patch also adds a simple test case that makes sure that
the example file is parsed correctly.

This patch implements basic configuration handling that reads a
configuration file and stores the parsed data in the ExecCtx and RunCtx
structs. It supports three configuration items:
- model (previously only --model)
- no_cache (previously only NITROCLI_NO_CACHE)
- verbosity (previously only --verbose)

In the past we were using an application global custom Result type
definition. This makes less sense now that we switched over to using
anyhow's Error and Result types. We kept that for the time being, but
with this change we remove the type and use anyhow::Result instead.

This patch changes our error handling approach from the ground up:
instead of having a globally used Error enum that contains variants for
all possible errors, we now use anyhow's Error type. This approach is
more dynamic (and not statically typed), but it allows for more fine
grained error messages and overall more user-friendly error reporting.
Overall it also is a net simplification. While we have one dynamic cast
now, in order to be able to handle erroneous password/PIN entries
correctly, that is considered a reasonable compromise.

This change wraps up the removal of the UnwrapError test trait. This
step prepares us for the subsequent removal of the application's global
Error enum type, in favor of the usage of anyhow's Error type.
|
| |
|
|
|
| |
This change marks the next step in getting rid of the UnwrapError test
trait. Specifically, it removes its unwrap_lib_err method.
|
| |
|
|

|
|
|

|

With upcoming changes we intend to move towards a model where we do not
distinguish the individual error variants the program deals with in a
global enum.
In preparation of such a change, this patch marks a first step in
removing the UnwrapError test trait, which relies on the existence of
exactly such typed errors. In particular, we remove the unwrap_str_err
method from it, basically falling back to just working with strings.

An arguably unrepresentative survey of services (GitHub, Google
Authenticator, and Bitbucket) seems to suggests that the base32 format
is the de-facto standard format for OTP secrets. Given that it's not
necessarily obvious what format a secret is in and that most services
refrain from mentioning it explicitly, having the correct default format
is fairly important.
With this change we switch the default format from hexadecimal to
base32 to accommodate for this finding.

We have never been fully satisfied with the name arg_defs. Now that we
have gotten rid of the formerly used args module, this change renames
arg_defs to args.
|
| |
|
|
|
|
| |
This change removes the args module by moving all remaining
functionality in it into main.rs. The result is arguably a nice
consolidation of all context related definitions in a single module.
|
| |
|
|
|
|
|
|
| |
This change marks the first step in a restructuring of the argument
handling code, the ultimate goal of which is a separation of the type
definitions as used by structopt from the logic associated with it. This
change in particular introduces a new module, arg_defs, that contains
all those type definitions that previously resided in the args module.

The -o/--otp-pin and -O/--no-otp-pin options to the config set command
are supposed to be mutually exclusive, with wrong usage detected by
structopt.
That is not the case currently, however, because the argument to
structopt's conflicts_with attribute is supposed to be the resulting
option and not the name of the variable capturing the result.
This change fixes the problem by changing the string accordingly.

This change updates the version of the nitrokey crate that we use to
0.5.1. As part of that, it replaces occurrences of Storage::get_status
with Storage::get_storage_status as the method has been renamed.

This patch changes the argument handling code to use structopt instead
of argparse using the data structures we introduced in the last patch.
As part of that transition we replace the old Error::ArgparseError
variant with ClapError that stores a structopt::clap::Error.
Because of that replacement, the format of the help messages changed,
breaking some of the tests. Hence, this change adapts them accordingly.
Also clap currently prints the version output to stdout, so we ignore
the version_option test case for now.
|
|
|
Now that all vendored dependencies have been removed, this change moves
the program's source code from the nitrocli/ directory into the root of
the repository.
