## 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

# 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
|
||||
|
||||
## Setup
|
||||
|
||||
### Prerequisites
|
||||
|
||||
```
|
||||
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/
|
||||
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
|
||||
|
||||
```
|
||||
cd dracut
|
||||
|
||||
sudo make install
|
||||
```
|
||||
|
||||
### 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`
|
||||
|
||||
```
|
||||
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
|
||||
|
||||
```
|
||||
mkdir /boot/fido2luks/
|
||||
cp /usr/bin/fido2luks /boot/fido2luks/
|
||||
cp /etc/fido2luks.conf /boot/fido2luks/
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
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
|
||||
cryptsetup luksHeaderBackup /dev/disk/by-uuid/<DISK_UUID> --header-backup-file luks_backup_<DISK_UUID>
|
||||
# There is no turning back if you mess this up, make sure you made a backup
|
||||
# You can also pass `--token` if you're using LUKS2 which will then store the credential in the LUKS header,
|
||||
# which will enable you to use `fido2luks open-token` without passing a credential as parameter
|
||||
fido2luks -i add-key --exclusive /dev/disk/by-uuid/<DISK_UUID>
|
||||
```
|
||||
|
||||
## 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.
|
||||
|
||||
Import the new config into env:
|
||||
|
||||
```
|
||||
set -a
|
||||
. /etc/fido2luks.conf
|
||||
```
|
||||
|
||||
Then add the new secret to each device and update dracut afterwards `dracut -f`
|
||||
|
||||
### Multiple keys
|
||||
|
||||
Additional/backup keys are supported, Multiple fido2luks credentials can be added to your /etc/fido2luks.conf file. Credential tokens are comma separated.
|
||||
```
|
||||
FIDO2LUKS_CREDENTIAL_ID=<CREDENTIAL1>,<CREDENTIAL2>,<CREDENTIAL3>
|
||||
```
|
||||
|
||||
## Removal
|
||||
|
||||
Remove `rd.luks.2fa` from `GRUB_CMDLINE_LINUX` in /etc/default/grub
|
||||
|
||||
```
|
||||
set -a
|
||||
. fido2luks.conf
|
||||
sudo -E fido2luks -i replace-key /dev/disk/by-uuid/<DISK_UUID>
|
||||
|
||||
sudo rm -rf /usr/lib/dracut/modules.d/96luks-2fa /etc/dracut.conf.d/luks-2fa.conf /etc/fido2luks.conf
|
||||

|
||||
## 0.3.0-alpha
|
||||
|
||||
This is just the program itself, all intitrid scripts are mostly taylored to the latest 0.2.x version and will most likely not work with 0.3.0 due to breaking changes in the CLI interface.
|
||||
I've decided it release the version in this state since I just do not have the time now or in the forseeable future to tewak all scripts since it's quite an tedious tasks which involves rebooting VMs countless times.
|
||||
If you're interested to adapt or write scripts for an particular distro I'd be more than happy to accept pull requests.

## 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>
|
||||
```
