## 0.3.0
|
||||
|
||||
* LUKS2 Tokens are now supported by every subcommand
|
||||
* `<credential>` has been converted into the flag `--creds`
|
||||
credentials provided by `--creds` will be supplemented from the LUKS header unless this is disabled by `--disable-token`
|
||||
* `fido2luks add-key` will take an `--auto-cred` flag which allows for credentials to be generated and stored without having to use `fido2luks credential`
|
||||
`fido2luks replace-key` will allow for credentials to be removed using the `--remove-cred` flag respectively
|
||||
* Removed `fido2luks open-token` subcommand
|
||||
`fido2luks open` now fulfills both functions
|
||||
* Added `fido2luks open --dry-run` flag, to perform the whole procedure apart from mounting the LUKS volume
|
||||
* Added an `--verbose` flag to display additional information like credentials and keyslots used if desired

## Setup
|
||||
### Setup
|
||||
|
||||
### Prerequisites
|
||||
#### Prerequisites
|
||||
|
||||
```
|
||||
```rust
|
||||
dnf install clang cargo cryptsetup-devel -y
|
||||
```
|
||||
|
||||
### Device
|
||||
#### Device
|
||||
|
||||
```
|
||||
```rust
|
||||
git clone https://github.com/shimunn/fido2luks.git && cd fido2luks
|
||||
|
||||
# Alternativly cargo build --release && sudo cp target/release/fido2luks /usr/bin/
|
||||
sudo -E cargo install -f --path . --root /usr
|
||||
|
||||
# Copy template
|
||||
cp dracut/96luks-2fa/fido2luks.conf /etc/
|
||||
# Name is optional but useful if your authenticator has a display
|
||||
echo FIDO2LUKS_CREDENTIAL_ID=$(fido2luks credential [NAME]) >> /etc/fido2luks.conf
|
||||
|
||||
# Load config into env
|
||||
set -a
|
||||
. /etc/fido2luks.conf
|
||||
|
||||
# Repeat for each luks volume
|
||||
# You can also use the `--token` flag when using LUKS2 which will then store the credential in the LUKS header,
|
||||
# enabling you to use `fido2luks open-token` without passing a credential as parameter
|
||||
sudo -E fido2luks -i add-key /dev/disk/by-uuid/<DISK_UUID>
|
||||
|
||||
# Test(only works if the luks container isn't active)
|
||||
sudo -E fido2luks -i open /dev/disk/by-uuid/<DISK_UUID> luks-<DISK_UUID>
|
||||
|
||||
```
|
||||
|
||||
### Dracut
|
||||
#### Dracut
|
||||
|
||||
```
|
||||
```rust
|
||||
cd dracut
|
||||
|
||||
sudo make install
|
||||
```
|
||||
|
||||
### Grub
|
||||
#### Grub
|
||||
|
||||
Add `rd.luks.2fa=<CREDENTIAL_ID>:<DISK_UUID>` to `GRUB_CMDLINE_LINUX` in /etc/default/grub
|
||||
|
||||
Note: This is only required for your root disk, systemd will try to unlock all other LUKS partions using the same key if you added it using `fido2luks add-key`
|
||||
|
||||
```
|
||||
```rust
|
||||
grub2-mkconfig > /boot/grub2/grub.cfg
|
||||
```
|
||||
|
||||
I'd also recommend to copy the executable onto /boot so that it is accessible in case you have to access your disk from a rescue system
|
||||
|
||||
```
|
||||
```rust
|
||||
mkdir /boot/fido2luks/
|
||||
cp /usr/bin/fido2luks /boot/fido2luks/
|
||||
cp /etc/fido2luks.conf /boot/fido2luks/
|
||||
```
|
||||
|
||||
## Testing
|
||||
### Test
|
||||
|
||||
Just reboot and see if it works, if that's the case you should remove your old less secure password from your LUKS header:
|
||||
|
||||
```
|
||||
# Recommend in case you lose your authenticator, store this backupfile somewhere safe
|
||||
```rust
|
||||
cryptsetup luksHeaderBackup /dev/disk/by-uuid/<DISK_UUID> --header-backup-file luks_backup_<DISK_UUID>

|
||||
|
||||
## Theory of operation
|
||||
|
||||
fido2luks builds on two basic building blocks, LUKS as an abstraction over linux disk encryption and and the FIDO2 extension [`hmac-secret`](https://fidoalliance.org/specs/fido-v2.0-rd-20180702/fido-client-to-authenticator-protocol-v2.0-rd-20180702.html#sctn-hmac-secret-extension).
|
||||
The `hmac-secret` extension allows for an secret to be dervied on the FIDO2 device from two inputs, the user supplied salt/password/keyfile and another secret contained within the FID2 device. The output of the `hmac-secret` function will then be used to decrypt the LUKS header which in turn is used to decrypt the disk.
|
||||
```
|
||||
|
||||
+-------------------------------------------------------------------------------+
|
||||
| |
|
||||
| +-----------------------------------------+ |
|
||||
| | FIDO2 device | |
|
||||
| | | |
|
||||
| | | |
|
||||
+-------+--------+ +------+ | +---------------+ | | +------------------------+
|
||||
| Salt/Password +-> |sha256+------------------------> | | | v | LUKS header |
|
||||
+----------------+ +------+ | | | | | | +---------------+
|
||||
| | | | +--------+ +------------------------+--------> |Disk master key|
|
||||
| | sha256_hmac +---------> | sha256 +-------> | Keyslot 1 | +---------------+
|
||||
+----------------+ | +----------+ | | | +--------+ +------------------------+
|
||||
| FIDO credential+---------------> |Credential| +----> | | | | Keyslot 2 |
|
||||
+----------------+ | |secret | | | | +------------------------+
|
||||
| +----------+ +---------------+ |
|
||||
| |
|
||||
| |
|
||||
+-----------------------------------------+
|
||||
|
||||
```
|
||||
Since all these components build upon each other losing or damaging just one of them will render the disk undecryptable, it's threfore of paramount importance to backup the LUKS header and ideally set an backup password
|
||||
or utilise more than one FIDO2 device. Each additional credential and password combination will require it's own LUKS keyslot since the credential secret is randomly generated for each new credential and will thus result
|
||||
in a completly different secret.

# fido2luks [](https://crates.io/crates/fido2luks)
|
||||
|
||||
This will allow you to unlock your LUKS encrypted disk with an FIDO2 compatible key.
|
||||
|
||||
Note: This has only been tested under Fedora 31, [Ubuntu 20.04](initramfs-tools/), [NixOS](https://nixos.org/nixos/manual/#sec-luks-file-systems-fido2) using a Solo Key, Trezor Model T
|
||||
|
||||
## Installation
|
||||
|
||||
### From Source
|
||||
|
||||
Installing from source requires the following dependencies:
|
||||
|
||||
Ubuntu: `cargo, libclang-dev, libcryptsetup-dev >= 2.2`
|
||||
|
||||
Fedora: `cargo, clang-devel, cryptsetup-devel`
|
||||
|
||||
To compile the fido2luks binary you can simply run `sudo cargo install --root /usr fido2luks` but since you may want to install the scripts included it this repo as well,
|
||||
it's recommended to clone the repo and install from there.
|
||||
|
||||
``
|
||||
git clone https://github.com/shimunn/fido2luks.git
|
||||
cargo install --root /usr --path fido2luks
|
||||
``
|
||||
|
||||
Continue with further instructions for [Ubuntu](initramfs-tools) or [Fedora](dracut)
|
||||
|
||||
### From Package
|
||||
|
||||
Ubuntu: see [releases](https://github.com/shimunn/fido2luks/releases)
|
||||
|
||||
NixOS: https://nixos.org/nixos/manual/#sec-luks-file-systems-fido2
|
||||
|
||||
ArchLinux:
|
||||
* [AUR](https://aur.archlinux.org/packages/fido2luks/)
|
||||
* [Git](PKGBUILD)
|
||||
|
||||
Fedora: coming soon
|
||||
|
||||
## Credentials
|
||||
|
||||
Depending on the version of cryptsetup and the age of your installation your LUKS header might be in the LUKS2 format already if that's the case fido2luks will be able to spare you from dealing with just another config file by simply storeing all the required information within your LUKS header.
|
||||
If your header is still using the LUKS1 format you may convert it:
|
||||
|
||||
```
|
||||
cryptsetup convert --type luks2 <device>
|
||||
```
|
||||
|
||||
if you want to keep using LUKS1 due to other software such as pam_mount not being compatible with LUKS2 at the moment, you will have to generate credentials by hand an add them to `/etc/fido2luks.conf` otherwise you can skip this step.
|
||||
```
|
||||
fido2luks credential [optional name]
|
||||
```
|
||||
the generated hexadecimal credential can then be added to `FIDO2LUKS_CREDENTIAL_ID=` in `/etc/fido2luks.conf` multiple credentials can be separated by comma.
|
||||
|
||||
## Adding a Key
|
||||
|
||||
If you had to generate a credential in the previous step you'll have to provide it to the following commands as a parameter or via an environment variable:
|
||||
|
||||
```
|
||||
set -a
|
||||
. /etc/fido2luks.conf
|
||||
```
|
||||
|
||||
To then add the key you need to have your current password/keyfile ready:
|
||||
|
||||
without having generated a credential in the previous step: `fido2luks -i add-key --gen-cred <device>`
|
||||
|
||||
with a keyfile: `fido2luks -i add-key --keyfile <path-to-keyfile <device>`
|
||||
|
||||
if you've confirmed at a later stage that everything works as expected you may want to remove your keyfile/password by running the previous commands with the `--exclusive` flag which will remove all other keys from the device.
|
||||
|
||||
## Replacing a Key
|
||||
|
||||
with password: `fido2luks -i replace-key <device>`
|
||||
|
||||
with keyfile: `fido2luks -i replace-key -d <path-to-keyfile> <device>`
|
||||
|
||||
with another fido2 derived key: `fido2luks -i replace-key -f <device>`

## fido2luks hook for mkinitcpio (ArchLinux and derivatives)
|
||||
|
||||
> ⚠️ Before proceeding, it is very advised to [backup your existing LUKS2 header](https://wiki.archlinux.org/title/dm-crypt/Device_encryption#Backup_using_cryptsetup) to external storage
|
||||
|
||||
### Setup
|
||||
|
||||
1. Connect your FIDO2 authenticator
|
||||
2. Generate credential id
|
||||
|
||||
```shell
|
||||
fido2luks credential
|
||||
```
|
||||
|
||||
3. Generate salt (random string)
|
||||
|
||||
```shell
|
||||
pwgen 48 1
|
||||
```
|
||||
|
||||
4. Add key to your LUKS2 device
|
||||
|
||||
```shell
|
||||
fido2luks add-key -Pt --salt <salt> <block_device> <credential_id>
|
||||
```
|
||||
|
||||
`-P` - request PIN to unlock the authenticator
|
||||
`-t` - add token (including credential id) to the LUKS2 header
|
||||
`-e` - wipe all other keys
|
||||
|
||||
For the full list of options see `fido2luks add-key --help`
|
||||
|
||||
5. Edit [/etc/fido2luks.conf](/initcpio/fido2luks.conf)
|
||||
|
||||
Keyslot (`FIDO2LUKS_DEVICE_SLOT`) can be obtained from the output of
|
||||
|
||||
```shell
|
||||
cryptsetup luksDump <block_device>
|
||||
```
|
||||
|
||||
6. Add fido2luks hook to /etc/mkinitcpio.conf
|
||||
|
||||
Before or instead of `encrypt` hook, for example:
|
||||
|
||||
```shell
|
||||
HOOKS=(base udev autodetect modconf keyboard block fido2luks filesystems fsck)
|
||||
```
|
||||
|
||||
7. Recreate initial ramdisk
|
||||
|
||||
```shell
|
||||
mkinitcpio -p <preset>
|
||||
```

## Initramfs-tools based systems(Ubuntu and derivatives)
|
||||
|
||||
For easiest installation [download and install the precompiled deb from releases.](https://github.com/shimunn/fido2luks/releases). However it is possible to build from source via the instructions on the main readme.
|
||||
After installation generate your credentials and add keys to your disk as described in the top-level README
|
||||
then add `initramfs,keyscript=fido2luks` to your `/etc/crypttab`
|
||||
|
||||
Example:
|
||||
```
|
||||
sudo -s
|
||||
|
||||
# Insert FIDO key.
|
||||
fido2luks credential
|
||||
# Tap FIDO key
|
||||
# Copy returned string <CREDENTIAL>
|
||||
|
||||
nano /etc/fido2luks.conf
|
||||
# Insert <CREDENTIAL>
|
||||
# FIDO2LUKS_CREDENTIAL_ID=<CREDENTIAL>
|
||||
|
||||
set -a
|
||||
. /etc/fido2luks.conf
|
||||
fido2luks -i add-key /dev/<LUKS PARTITION>
|
||||
# Current password: <Any current LUKS password>
|
||||
# Password: <Password used as FIDO challange>
|
||||
# Tap FIDO key
|
||||
|
||||
nano /etc/crypttab
|
||||
# Append to end ",discard,initramfs,keyscript=fido2luks"
|
||||
# E.g. sda6_crypt UUID=XXXXXXXXXX none luks,discard,initramfs,keyscript=fido2luks
|
||||
|
||||
update-initramfs -u
|
||||
|
||||
|
||||
sda6_crypt UUID=9793d81a-4cfb-4712-85f3-c7a8d715112c none luks,discard,initramfs,keyscript=fido2luks
|
||||
```
|
||||
|
||||
But don't forget to run `make install` which will install all necessary scripts and regenerate your intrid.

|
||||
//! ## Command line interface
|
||||
//! ### Generating a credential
|
||||
//! Credentials can be generated by using `fido2luks credential`
|
||||
//! this command will take an optional string as username your authenticator might be able to display
|
||||
//!
|
||||
//! `fido2luks credential 'My 2FA protected disk'`
|
||||
//!
|
||||
//! It is advisable to repeat this step and the next step for more than one authenticator, as backup
|
||||
//! ### Securing a disk
|
||||
//! To utilise the previously generated credential you simply run
|
||||
//!
|
||||
//! `fido2luks -i add-key <device> [<credential>,..]`
|
||||
//!
|
||||
//! You can also use `fido2luks -i add-key --exclusive <device> [<credential>,..]`
|
||||
//!
|
||||
//! which will add a new key and then remove ALL other keys.
|
||||
//! This command supports a fair amount of options for instance `--keyfile` which will allow you to
|
||||
//! add an authenticator to the `<device>`
|
||||
//!
|
||||
//! `-f` will utilise an previously added fido protected key to add another one
|
||||
//!
|
||||
//! `--token` will store the credential within the LUKS header, making it easily accessible even if
|
||||
//! you're unable to boot your system.
|
||||
//!
|
||||
//!
|
||||
//! `fido2luks -i replace-key <device> [<credential>,..]`
|
||||
//! works in a similar fashion but instead of adding a new key it'll update an existing one
|
||||
//!
|
||||
//!
|
||||
//! ### Unlocking a disk
|
||||
//! To open an LUKS container using your authenticator you simply run
|
||||
//!
|
||||
//! `fido2luks -i open <device> <name> [<credential>,..]`
|
||||
//!
|
||||
//! if successful your LUKS container will be accessible under `/dev/mapper/<name>`
|
||||
//! To avoid having to specify your credentials you may want to to use
|
||||
//!
|
||||
//! `fido2luks -i open-token <device> <name>`
|
||||
//!
|
||||
//! which should even be faster since it allows for the credential to be matched to the right keyslot
|
||||
//!
|
||||
//!
|
||||
//! ### Common options
|
||||
//!
|
||||
//! `--salt` Determines what data will be provided to the authenticator in order to derive the secret, the default being `ask` which will prompt the user for an password.
|
||||
//! Alternatives being `file:<PATH>` where the specified file will be hashed and then used as input, the same goes for the `string:<STRING>` option which will behave in the same manner as the `ask` option.
|
||||
//!
|
||||
//! `--pin` Allows for a PIN to be passed to the authenticator if needed, it is however recommended not to use a PIN since the bootscript doesn't support this feature atm.
|
||||
//!
|
||||
//! `--help` Will provide context dependant help for each command

//! ```
|
||||
//! dnf install clang cargo cryptsetup-devel -y
|
||||
//! ```
|
||||
//!
|
||||
//! ### Device
|
||||
//!
|
||||
//! ```
|
||||
//! git clone https://github.com/shimunn/fido2luks.git && cd fido2luks
|
||||
//!
|
||||
//! # Alternativly cargo build --release && sudo cp target/release/fido2luks /usr/bin/

//!
|
||||
//! Add `rd.luks.2fa=<CREDENTIAL_ID>:<DISK_UUID>` to `GRUB_CMDLINE_LINUX` in /etc/default/grub
|
||||
//!
|

|
||||
//!
|
||||
//! ```
|
||||
//! grub2-mkconfig > /boot/grub2/grub.cfg

||||

|
||||
//!

|
||||

|
||||
//!
|
||||
//! ## Addtional settings
|
||||
//!
|
||||
//! ### Password less
|
||||
//!
|
||||
//! Remove your previous secret as described in the next section, in case you've already added one.
|
||||
//!
|
||||
//! Open `/etc/fido2luks.conf` and replace `FIDO2LUKS_SALT=Ask` with `FIDO2LUKS_SALT=string:<YOUR_RANDOM_STRING>`
|
||||
//! but be warned that this password will be included to into your initramfs.
