This patch implements the pin unblock command that unblocks and resets
the user PIN. The name unblock is chosen over libnitrokey's unlock to
be consistent with the GnuPG terminology and to avoid confusion with the
unrelated lock command.

We have functionality for changing the Nitrokey's user & admin PINs as
well as for resetting the user PIN coming up. With the prospect of this
new functionality arriving, it makes sense to introduce a new top-level
command for the sole purpose of PIN management.
This change introduces such a command, pin, and moves the existing clear
command for clearing the PIN cache into it.
|
| |
|
|
|
|
|
| |
The mode argument is used to specify the context of the pinentry dialog:
querying an existing passphrase or prompting the user to choose a new
PIN. It is used to choose a description and to decide whether to show a
quality bar that measures the password strength.

This patch changes the otp get command to set the Nitrokey's time before
generating a one-time password using the TOTP algorithm. Per default,
it sets the time to the current system time. If the --time option is
set, it uses its value instead. See issue #34 [0] for a discussion of
this change.

The main change introduced in this patch is the correct usage of - and
\-. Instead of the \(em macro for em-dashes as suggested by
man-pages(7) it uses the \(en macro: Both dashes are typeset as a
single UTF-8 character on my terminal. If spaces are omitted, the
resulting text is very hard to read if set in monospace fonts as the en-
or em-dash is not significantly different from a regular dash. The
em-dash may not be used with spaces, hence the usage of en-dash.

The man page incorrectly documented the otp get command twice. The
second occurrence is supposed to detail the otp clear command. This
change adjusts the code accordingly.
|
| |
|
|
|
| |
This patch adds documentation and examples for config get and config set
to the README and to the man page.
|
| |
|
|

This patch adds a short description of the Nitrokey OTP capabilities to
the OTP section of the man page. This should make it easier to
understand the commands without prior knowledge of the Nitrokey devices.

The 'status' command has traditionally printed information about the
connected Nitrokey and that included storage specific data if the device
present is a Nitrokey Storage.
Given that we have a root-level 'storage' command it arguably makes
sense to move the printing of the storage related status information
into a 'status' sub-command of the said command, which makes the output
more predictable.
|
| |
|
|
|
|
|
|
| |
We have kept the code organized such that the function for handling a
command is located above the functions taking care of handling the
subcommands.
This change moves the storage_* subcommand functions below the storage
function to be more consistent with existing code.

Upon their inception, the 'open' and 'close' commands were pretty much
the only relevant commands the program provided and it made sense to
have them reside in the root namespace. By now we support more commands
and have started to structure them in a more hierarchical fashion.
To go with the flow, this change introduces a new 'storage' command and
makes the existing 'open' and 'close' commands subcommands of it. We
chose the name 'storage' (over, say, 'volume') because we plan to move
the printing of the storage related status from the 'status' root level
command into a subcommand within 'storage'.
|
| |
|
|
|
|
|
| |
With recent refactorings the output of the status command changed
slightly.
With this patch we update the README that happens to provide an example
of said output in accordance with this change.
|

The Nitrokey UG was generous enough to sponsor a Nitrokey Pro as well as
a Nitrokey Storage device for development and testing of the program.
This change mentions the company in the acknowledgments section of the
README.
|
| |
|
|
|

This patch adds the otp commands to the README and describes them in the
nitrocli(1) man page.

This change implements the config set subcommand. The subcommand changes
the configuration of a Nitrokey device.
Its structure is more complex as it allows partial modifications: The
user does not have to change all settings, but may choose to change only
some. At the same time, the binding settings can be either set to a
value or disabled. Therefore, we have the --{num,caps,scrol}lock
options to set a value and the --no-{num,caps,scrol}lock options to
disable the value. If none of the two is set, the setting is not
changed.
|
| |
|
|
|
| |
This change implements the config get subcommand. The subcommand reads
the device configuration and prints it.
|
| |
|
|
|
| |
This patch adds the top-level config command. Its subcommands will
provide access to the device configuration.
|
| |
|
|
|
|
|
|
| |
Currently, the status command fails for a Nitrokey Pro. This patch
changes the command to also print basic status information for Pro
devices. For the sake of consistency, the common status is always
queried using the common `Device` functions, even if the Storage status
includes the same information.
|
| |
|
|
|
|
| |
This patch extracts the print_status function that prints the status
fields common to all supported Nitrokey devices from the
print_storage_status function.
|
| |
|
|
|
| |
The print_status function only prints the Storage-specific status
struct. Therefore it is renamed to print_storage_status.
|
| |
|
|
|
|
| |
This change adds a new section for acknowledgments surrounding the
program to the README. Robin Krahl (robinkrahl @ Github) has been a
great help with respect to recent developments.

This patch introduces the `otp status` subcommand that lists all OTP
slots and their current status. To avoid hardcoding the number of slots
per type, we iterate all slots until we get an `InvalidSlot` error
(assuming that the set of valid slots is {0, ..., n} for some n). The
`status` command is quite slow as we have to query each slot separately.
|
| |
|
|
| |
This patch implements the `otp clear` subcommand that erases an OTP slot.
|
| |
|
|
|
|
|
|
|
|
| |
This patch implements the `otp set` subcommand that configures an OTP
slot. There are two ways to specify an OTP secret: as a hexadecimal
string (that means that every two characters are interpreted as a
hexadecimal representation of one byte of the secret) or as an ASCII
string (that means that the ASCII code of every character is interpreted
as one byte of the secret). As the HOTP RFC mentions both
representations, this implementation supports both.

This patch implements the `otp get` subcommand that allows the user to
generate a one-time password on the Nitrokey device. Before generating
the password, the device configuration is checked so that the user only
has to enter a PIN if it is required for the OTP generation.
|
| |
|
|
|
| |
This patch adds the `otp` top-level command. Its subcommands provide
access to one-time passwords on the Nitrokey.
|
| |
|
|
|
|
| |
This patch implements authentication with the user or admin PIN. This
is a preparation for the `otp get` and `otp set` commands which require
user and admin access to the Nitrokey.
|
| |
|
|
|
|
| |
Currently, we only clear the user PIN if clear is called. This patch
changes the clear command to also clear the admin PIN as we will start
to use the admin PIN in upcoming patches.
|

Currently, `open` directly calls the `pinentry` module and loops until
the user entered a correct passphrase or the retry limit is reached.
This patch moves the pinentry call and the loop into the
`try_with_passphrase_and_data` function. This function queries a
passphrase of a given type and executes a function with that passphrase.
This function has a data argument and may return data that is passed to
the next call of the function (if it failed).
This data-passing mechanism is required for the `nitrokey`
authentication functions: These functions take ownership of the device
and either return an authenticated device after successful
authentication, or an error including the unauthenticated device if the
authentication failed. This patch enables the usage of these functions
in future patches.
|
| |
|
|
|
|
|
| |
Currently, invalid UTF-8 code points in the passphrase returned by
pinentry are replaced with replacement characters by
`String::from_utf8_lossy`. This patch changes the code to use
`String::from_utf8` and returns an UTF-8 error if encountered.

This patch replaces the macro for argument parsing with
`argparse::ArgumentParser` from the argparse crate. It moves the
application logic to the `commands` module and the argument parsing to
the `options` module. An enum is used to represent the available
commands. The code is based on the `subcommands.rs` example shipped
with argparse.
|
| |
|
|
|
|
|
| |
In order to prepare for the new argument parsing support based on the
argparse crate, this change factors out the existing code used for
responding to commands in a new file, commands.rs. No semantic change is
introduced.

Spaces in the arguments for gpg-connect-agent’s `GET_PASSPHRASE` command
have to be esaced using a plus sign. Somehow this was missing for the
prompt argument. This patch adds escaping for the prompt so that the
pinentry dialog is displayed correctly.

In the past we have used the 'devel' branch for more or less early
development work that includes the occasional rebase to fix up mistakes
and keep the history clean. That is a non-starter when it comes to
tagging signed releases, which we have introduced recently.
Hence, there is no point in diverging from what the rest of the world is
doing by using a branch name other than 'master' as the main development
vehicle.
By now we have introduced two dependencies on the branch name into the
code base, which this change fixes up.

This change enables automated code format checking by means of the
rustfmt program in the Gitlab CI pipeline. The check is performed in a
third job in the hope that this helps identify problems more easily:
users can see which of the jobs failed and focus on them in isolation,
as opposed to having a single log file or, worse, just the results of
the stages up to the first failure.
This patch resolves issue #17.

An automated code formatter can help tremendously in reducing the amount
of cognitive energy wasted on thinking about the "best" formatting of
code as well as the number of nitpicks reviews typically get -- the
format is machine checked (and enforced) and there is usually little to
no discussion about the validity.
To reach the goal of having such automated enforcement, we want to run
the rustfmt tool as part of the CI pipeline. With rustfmt having reached
1.0 recently, the believe is that by now the formatting is reasonably
stable and usable for this purpose.
In that light, this change formats the code using rustfmt and prepares
for such an automated style check.

This patch adds a new target to the pipeline that installs clippy and
then uses it to check for various potential problems in the crate.
|
| |
|
|
|
|
|
| |
After the switch to using the nitrokey crate for communication with the
device, we have to warnings standing in the way of enabling clippy
unconditionally for the nitrocli crate. This change fixes those two
warnings.

This change adds another two badges to the repository. The first one
simply lists the most recent version of the crate as published on
crates.io. The second one states the minimum version of rustc that is
required for building. We have recently switched to using Rust 2018 and
with that we have a requirement for version 1.31 of the toolchain. In
the future the hope is that now that we have a proper CI/CD pipeline
based off of Docker images we should be able to build on past versions
of Rust, even if they are not used during development.

This change adds a configuration file for the Gitlab CI/CD pipeline to
the repository. This file (directly or indirectly) controls the
environment in which to build, what exactly to build, and ultimately
would also be used to define what tests to run.
With the pipeline in place the change also adds a badge indicating the
status of the build on the project's front page.
The following other CI services have been evaluated or tested and found
to be insufficient for the needs at hand:
- Travis CI: Does not support configuration in a directory other than
the repository root
- Cirrus CI: Has the same problem
- Semaphore: Does not support Rust
- Circle CI: Does not support Rust
- Google Cloud Build: Pretty much strictly a paid service

Currently, the nitrokey crate is renamed to libnitrokey in Cargo.toml as
there used to exist a nitrokey module in this crate. As this module
does no longer exist and is not likely to return, this patch removes the
customized name for the nitrokey crate.

This patch removes all dependencies that are no longer required since
the hidapi communication is replaced by libnitrokey.
Delete subrepo hid/:hid
Delete subrepo hidapi-sys/:hidapi-sys
Delete subrepo pkg-config/:pkg-config
|
| |
|
|
|
|

This patch removes the raw hidapi implementation of the status command
and all utility methods that are no longer needed. With this patch, all
device communication is performed using libnitrokey.
|

This patch removes the raw hidapi implementations of the Enable
Encrypted Volume and Disable Encrypted Volume commands and replaces them
with the methods enable_encrypted_volume and disable_encrypted_volume of
the Storage struct provided by the nitrokey trait.
To provide some context to the error messages, the errors are wrapped
using the map_err method of the Result enum and the get_error function
that combines a nitrokey error code and a string into a nitrocli error.
It would be more idiomatic to define a conversion from a nitrokey error
to a nitrocli error, but then we would lose information about the
context of the error.

The nitrokey crate provides a simple interface to the Nitrokey Storage
and the Nitrokey Pro based on the libnitrokey library developed by
Nitrokey UG. The low-level bindings to this library are available in
the nitrokey-sys crate.
This patch adds version v0.2.1 of the nitrokey crate as a dependency
for nitrocli. It includes the indirect dependencies nitrokey-sys
(version 3.4.1) and rand (version 0.4.3).

This change bumps the version of the crate to 0.1.3. The following
notable changes have been made since 0.1.2:
- Show PIN related errors through pinentry native reporting mechanism
instead of emitting them to stdout
- Added a man page (nitrocli(1)) for the program to the repository
- Adjusted program to use Rust Edition 2018
- Applied a couple of clippy reported suggestions
- Added categories to Cargo.toml
- Changed dependency version requirements to be less strict (only up to
the minor version and not the patch level)
- Bumped pkg-config dependency to 0.3.14
- Bumped libc dependency to 0.2.45
- Bumped cc dependency to 1.0.25

Given that development is picking up speed again we should accept all
the help we get from the compiler to catch issues as early as possible.
To that end, this change enables more lints for the program. As "usual",
lints that are suspected to potentially change in future versions of
Rust are reported as warnings and not errors.
