* Display available extensions in the help textDaniel Mueller2020-10-11
| | | | | | | | | With recent changes we are able to execute user-provided extensions through the program. However, discoverability is arguably lacking, because nitrocli provides no insight into what extensions are available to begin with. This patch changes this state of affairs by listing available extensions in the help text.
* Introduce support for user-provided extensionsDaniel Mueller2020-10-11
| | | | | | | | | | | | | | This change introduces support for discovering and executing user-provided extensions to the program. Extensions are useful for allowing users to provide additional functionality on top of the nitrocli proper. Implementation wise we stick to an approach similar to git or cargo subcommands in nature: we search the directories listed in the PATH environment variable for a file that starts with "nitrocli-", followed by the extension name. This file is then executed. It is assumed that the extension recognizes (or at least not prohibits) the following arguments: --nitrocli (providing the path to the nitrocli binary), --model (with the model passed to the main program), and --verbosity (the verbosity level).
* Rename numlock, capslock, scrollock optionsRobin Krahl2020-10-11
| | | | | | | | | | | | | | This patch renames the options for the config set command: --numlock ==> --num-lock --capslock ==> --caps-lock --scrolllock ==> --scroll-lock --no-numlock ==> --no-num-lock --no-capslock ==> --no-caps-lock --no-scrolllock ==> --no-scroll-lock The original naming was based on a typo in nitrokey-rs (scrollock vs. scrolllock). Also, the typical spelling for the keys is Num Lock, Caps Lock and Scroll Lock, so using a hyphen is a more natural.
* Remove DeviceModel::as_user_facing_strRobin Krahl2020-10-11
| | | | | | | This patch removes the unused DeviceModel::as_user_facing_str method. The device model is only used for the argument handling. When printing messages for the user, we always use nitrokey::Model. Its Display implementation already prints the model in an appropriate format.
* Support Librem KeyRobin Krahl2020-10-11
| | | | This patch adds the librem device model for the Librem Key.
* Update nitrokey to v0.8.0Robin Krahl2020-10-11
| | | | | | This patch updates the nitrokey dependency to version 0.8.0 and applies all breaking changes (Config fields renaming, DeviceWrapper and Model non-exhaustiveness, changed Display implementation for Model).
* Shorten some error handling pathsDaniel Mueller2020-09-29
| | | | | | | | | When we originally switched over to using anyhow for error handling, we evidently missed to take advantage of its context support in a couple of error paths. The result was that we ended up with rather long winded > result.ok_or_else(|| anyhow::anyhow!(...)) constructs. This change shortens them, making use of the anyhow::Context trait.

* Add the --progress option to the fill commandRobin Krahl2020-09-20
| | | | | | | The fill command starts a background operation on a Nitrokey Storage device that fills the SD card with random data. This patch adds a new option, --progress, to the fill command that checks if a fill operation is already running on the device and shows its progress.
* Show progress bar in fill outputRobin Krahl2020-09-12
| | | | | This patch uses the progressing crate to display a progress bar for the fill command if the output is printed to a TTY.
* Add is_tty field to ContextRobin Krahl2020-09-12
| | | | | | This patch adds the is_tty field to the Context struct that indicates whether stdout is a TTY. This allows us to use TTY features like moving the cursor in our output.
* Add fill command to overwrite SD cardRobin Krahl2020-09-12
| | | | | | 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 Krahl2020-09-11
| | | | | | | | | | 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 Krahl2020-09-09
| | | | | 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 Krahl2020-09-09
| | | | | | | | | | | | | 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 Krahl2020-09-07
| | | | | | | | | | | | | 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.

* Add --serial-number optionRobin Krahl2020-09-07
| | | | | | | | This patch adds the --serial-number option that allows the user to filter the attached Nitrokey devices by serial number. As the Nitrokey Storage does not include its serial number in the USB device descriptor and as we don't want to connect to it just to query the serial number, this option only works for Nitrokey Storage devices.
* Fail if multiple matching devices are attachedRobin Krahl2020-09-07
| | | | | | | | Previously, we just applied our filter (if any) to all attached Nitrokey devices and selected the first match when connection to a Nitrokey device. This may lead to unexpected behavior if multiple devices are attached. This patch changes the find_device function to return an error if multiple matching devices are found.
* Refactor connection handlingRobin Krahl2020-09-07
| | | | | | | | | | 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.
* Add Context::from_env constructorRobin Krahl2020-09-05
| | | | | This patch adds the from_env constructor to Context to make the main function easier to read.
* Merge ExecCtx and RunCtx into ContextRobin Krahl2020-09-05
| | | | | | | 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.
* Remove Stdio traitDaniel Mueller2020-09-03
| | | | | | | With the switch from argparse over to structopt a while back the need for the Stdio trait that we used for abstracting over the different contexts vanished. With this change we remove the trait and its various implementations.
* Add --no-cache option to bypass PIN cacheRobin Krahl2020-09-05
| | | | | | | | This patch adds a new --no-cache option that corresponds to the NITROCLI_NO_CACHE environment variable and the no_cache configuration. This makes the user interface more consistent as all configuration items are now backed by both an environment variable and a command-line option.
* Add config test case and example config fileRobin Krahl2020-09-05
| | | | | | | | 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.
* Use standard configuration file locationsRobin Krahl2020-09-05
| | | | | | | | | This patch uses the directories crate to query the appropriate path for the configuration files. For Linux, paths according to the XDG Base Directory Specification are used. Note that directories does not yet support the XDG_CONFIG_DIRS variable for system-wide configuration files. Therefore we only use a user configuration file.
* Use envy to parse environment variables for ConfigRobin Krahl2020-09-05
| | | | | | | | This patch uses the envy crate to parse the environment. A variable NITROCLI_KEY can be used to overwrite the configuration for *key*. This has the side effect that the NITROCLI_NO_CACHE variable is evaluated as a boolean variable (instead of only checking whether it is set). We also accept two new variables, NITROCLI_MODEL and NITROCLI_VERBOSITY.
* Implement configuration handlingRobin Krahl2020-09-05
| | | | | | | | | 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 warning for missing_copy_implementations lintDaniel Mueller2020-09-01
| | | | | | | The missing_copy_implementations lint is arguably not super useful in an application crate, where no third party is consuming the type definitions. As such, this change removes it from the list of lints causing warnings.
* 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.
* Remove no longer used error moduleDaniel Mueller2020-08-31
| | | | | | This change removes the error module. This module, and the Error type it homes, are no longer used by the application, as everything has been transitioned over to using anyhow's Error type.
* Remove no longer necessary msg parameter from try_with_* functionsDaniel Mueller2020-08-29
| | | | | | | | | With the move to using anyhow's Error type and adding contextual information at the point where we bubble up errors, we no longer require the 'msg' argument that is passed to the try_with_pin_* and authenticate functions. To that end, this change removes this parameter, concluding the switch to using anyhow.
* 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.
* Refrain from using Error::Error variant in pinentry testsDaniel Mueller2020-07-09
| | | | | | | | The pinentry tests currently expect the Error::Error variant to be reported for failures. This patch adjusts the tests to merely compare strings and ignore the exact type of error. Doing so will make it easier to switch to using anyhow for error handling.
* 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.
* Correctly use doc comments in macrosDaniel Mueller2020-07-03
| | | | | | | | | | | | | | | | Our custom macros for conveniently creating types with additional meta information for working with structopt do not actually use the doc comments we have in place -- these comments are solely for in-source documentation. We are an application and as such crates.io will not automatically generate documentation. All of that does not deter rustc from complaining that doc comments are unused. In the past we tried to fudge that by adding a special allowance, #[allow(unused_doc_comments)], but that seems to have seized to work. With this change we finally give in and move the doc comment into the macro itself, where it will be used to annotate the generated type. This step should hopefully silence rustc once and for all -- at the expense of a slight decrease in readability.
* 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.
* Merge config_set function into commands.rsDaniel Mueller2020-04-11
| | | | | | As a next step moving us closer towards removing the args module, this change merges the config_set function into the existing function of the same name in the commands module.
