A hardware password manager, built around a Paspberry Pi Zero and pass, the UNIX password manager.
This is also an entry for Hackaday.io's Pi Zero Contest.
I am using a Raspberry Pi Zero, since it has USB-OTG support and a lot of GPIO to interface an OLED screen, a button matrix for input and maybe even an ESP8266 for WiFi. The OLED I am intending to use has an I²C interface and a screen diagonal of .96".
The neccessary drivers are available only in the Raspbian 4.4 Kernel, which you can install using
sudo BRANCH=next rpi-update
You also need to activate the device tree overlay dwc2 and load the corresponding kernel module:
echo "dtoverlay=dwc2" | sudo tee /boot/config.txt
echo "dwc2" | sudo tee /etc/modules
To use this program, you have to enable the libcomposite driver on the Raspberry Pi and create a USB HID gadget.
You can use this bash script:
#!/bin/bash
# this is a stripped down version of https://github.com/ckuethe/usbarmory/wiki/USB-Gadgets - I don't claim any rights
modprobe libcomposite
cd /sys/kernel/config/usb_gadget/
mkdir -p g1
cd g1

mkdir -p configs/c.$C/strings/0x409
echo "Config $C: ECM network" > configs/c.$C/strings/0x409/configuration

ln -s functions/hid.$N configs/c.$C/
ls /sys/class/udc > UDC
The version of (pass)[https://passwordstore.org] doesn't format the output as nice, so it is easier to work with. Using the pass-installer.sh will automatically clone from the original repository, apply the patch and install it (make sure, patch and sudo is installed).
You can then check out hardpass-demo.sh to see how to supply a passphrase directly from the command line (without gpg-agent). Keep in mind, that it will show up in your history file!
