* Add fill command to overwrite SD cardRobin Krahl2021-01-10
| | | | | | 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.
* Print SD card usage in Storage statusRobin Krahl2021-01-10
| | | | | | | | | | 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.
* Rename device path to USB path in list outputRobin Krahl2021-01-10
| | | | | For consistency with the --usb-path option, this path renames the device path column in the output of the list command to USB path.
* Add --usb-path option to select deviceRobin Krahl2021-01-10
| | | | | | | | | | | | | 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.
* Add test cases for new connection logicRobin Krahl2021-01-10
| | | | | | | | | | | | | 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.
* Refactor connection handlingRobin Krahl2021-01-10
| | | | | | | | | | 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.
* Introduce builder-inspired way for configuring Nitrocli instanceDaniel Mueller2020-08-24
| | | | | | | | 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.
* Remove Nitrocli::model methodDaniel Mueller2020-09-05
| | | | | | | | 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.
* Adjust copyright & license specification to comply with REUSE 3.0Daniel Mueller2020-09-02
| | | | | | | | 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.
* Adjust copyright string to refer to The Nitrocli DevelopersDaniel Mueller2020-09-01
| | | | | This change adjusts the copyright header in all files to no longer mention individuals but refer to The Nitrocli Developers in general.
* Merge ExecCtx and RunCtx into ContextRobin Krahl2021-01-10
| | | | | | | 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.
* Add config test case and example config fileRobin Krahl2021-01-10
| | | | | | | | 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.
* Implement configuration handlingRobin Krahl2021-01-10
| | | | | | | | | 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)
* Remove application global Result definitionDaniel Mueller2020-08-31
| | | | | | | 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.
* Use anyhow for error handlingDaniel Mueller2020-08-28
| | | | | | | | | | | 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.
* Remove UnwrapError test traitDaniel Mueller2020-07-09
| | | | | | 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.
* Remove unwrap_lib_err method from UnwrapError test traitDaniel Mueller2020-07-09
| | | | | This change marks the next step in getting rid of the UnwrapError test trait. Specifically, it removes its unwrap_lib_err method.
* Remove unwrap_str_err method from UnwrapError test traitDaniel Mueller2020-07-08
| | | | | | | | | | 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.
* Change default OTP format to base32Daniel Mueller2020-07-07
| | | | | | | | | | | 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.
* Rename arg_defs.rs to args.rsDaniel Mueller2020-04-11
| | | | | | 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.
* Merge remaining bits of args.rs into main.rsDaniel Mueller2020-04-11
| | | | | | 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.
* Factor out arg_defs.rs for argument parsing related typesDaniel Mueller2020-04-01
| | | | | | | | 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.
* Provide correct mutual exclusion between config set -o and -O optionsDaniel Mueller2020-01-24
| | | | | | | | | | 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.
* Add unit tests for the list commandRobin Krahl2020-01-14

* Bump nitrokey dependency to version 0.5.1Robin Krahl2020-01-14
| | | | | | 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.
* Replace argparse with structoptRobin Krahl2020-01-07
| | | | | | | | | | | | 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.
* Move nitrocli source code into repository rootDaniel Mueller2020-04-04
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.
