  • That was really hard to do. I created a note for myself and I will also publish it on my website. You can also decrypt the sd using fido2 hardware key (I have a nitrokey). If you don’t need that just skip steps that are for fido2.

    The note:

    Download the image.

    Format SD card to new DOS table:

    • Boot: 512M 0c W95 FAT32 (LBA)
    • Root: 83 Linux

    As root:

    xz -d 2023-12-11-raspios-bookworm-arm64-lite.img.xz
    losetup -fP 2023-12-11-raspios-bookworm-arm64-lite.img
    dd if=/dev/loop0p1 of=/dev/mmcblk0p1 bs=1M
    cryptsetup luksFormat --type=luks2 --cipher=xchacha20,aes-adiantum-plain64 /dev/mmcblk0p2
    systemd-cryptenroll --fido2-device=auto /dev/mmcblk0p2
    cryptsetup open /dev/mmcblk0p2 root
    dd if=/dev/loop0p2 of=/dev/mapper/root bs=1M
    e2fsck -f /dev/mapper/root
    resize2fs -f /dev/mapper/root
    mount /dev/mapper/root /mnt
    mount /dev/mmcblk0p1 /mnt/boot/firmware
    arch-chroot /mnt
    

    In chroot:

    apt update && apt full-upgrade -y && apt autoremove -y && apt install cryptsetup-initramfs fido2-tools jq debhelper git vim -y
    git clone https://github.com/bertogg/fido2luks && cd fido2luks
    fakeroot debian/rules binary && sudo apt install ../fido2luks*.deb
    cd .. && rm -rf fido2luks*
    

    Edit /etc/crypttab:

    root            /dev/mmcblk0p2          none            luks,keyscript=/lib/fido2luks/keyscript.sh
    

    Edit /etc/fstab:

    /dev/mmcblk0p1    /boot/firmware  vfat    defaults          0       2
    /dev/mapper/root  /               ext4    defaults,noatime  0       1
    

    Change root to /dev/mapper/root and add cryptdevice=/dev/mmcblk0p2:root to /boot/firmware/cmdline.txt.

    PATH="$PATH:/sbin"
    update-initramfs -u
    

    Exit chroot and finish!

    umount -R /mnt

    On my Raspberry Pi 4 4gb with encrypted sd is:

    • pihole
    • wireguard server
    • vaultwarden
    • cloudflare ddns
    • nginx proxy manager
    • my website
    • ntfy server
    • mollysocket
    • findmydevice server
    • watchtower

    Pi is overkill for this kind of job. Load average is only 0.7% and ram usage is only 400M

    Thanks for advice! If I upgrade to proton unlimited for next 2 years I get 500gb of cloud storage and (imo) a little worse but still great VPN for 3,5$ less per month.

    Do I have unlimited aliases on Proton Pass or also on SimpleLogin? You can login to simplelogin using proton account.

    I have 15 days left on MullvadVPN and maybe 2 months on SimpleLogin. I’ll upgrade next month.
