Secure AlmaLinux (RHEL) Server setup with LUKS encryption, Tang, TPM and RAID1 for Hetzner Dedicated Servers.

## Features

- AlmaLinux Server base
- Full disk encryption with LUKS
- Remote unlock via Tang server
- TPM-based boot verification
- mdadm RAID1 + XFS (RHEL standard)
- SSH key-only access with early boot SSH via dropbear
- Best-in-class terminal: zsh + powerlevel10k + evil tmux

## Unlock Strategy

1. **Automatic unlock via Tang/TPM** (default):
   - Configure TPM2 and/or Tang servers in post-install.sh
   - System unlocks automatically if conditions are met
   - No manual intervention required

2. **Manual unlock via SSH** (fallback):
   - SSH to server on port 22 (dropbear in early boot)
   - Enter LUKS passphrase when prompted (twice, once per disk)
   - Used when automatic unlock fails or is not configured

## Install

Boot your Hetzner server into rescue mode and run:

```bash
wget -qO- https://git.dominik-roth.eu/dodox/nullpoint/raw/branch/master/get.sh | bash
```

The installer will:
- Detect your SSH key from the current session
- Ask for hostname and username
- Generate a secure LUKS passphrase (SAVE IT!)
- Download and configure everything
- Run Hetzner's installimage automatically
