We designed a custom case
milled from solid aircraft-grade aluminum that physically closes
access to all ports except power and ethernet, making it
resistant to Evil Maid attacks. Additionally, we disable SSH,
USB, and Wifi on the device. A user boots it up, and an e-paper
display will show a QR code with the address to their Hush Line
Onion Service instance.
