Arch Linux ARM 64 on Raspberry Pi 3 B+ With Full Disk Encryption And SSH Unlock: 2018 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

Differences to the 32-bit arch linux arm version:

• probably better performance
• can run 64-bit software
• comes without the proprietary video-driver blobs

Generating Authy passwords on other authenticators

---

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

---

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

If you're not familiar: What is fail2ban? fail2ban is an awesome linux service/monitor that scans log files (e.g. auth.log for SSH) for potentially malicious behavior. Once fail2ban is tripped it will ban users for a specified duration by adding rules to Iptables. If you're unfamiliar with fail2ban Chris Fidao has a wonderful (& free!) series about security including setting up fail2ban here.

Recently Laravel released a new feature in 5.1 to throttle authentication attempts by simply adding a trait to your authentication controller. The Laravel throttle trait uses the inputted username, and IP address to throttle attempts. I love seeing this added to a framework out of the box, but what about some of our other apps not built on Laravel? Like a WordPress login? Or even an open API etc.? Ultimately,

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:
