Requirements / Recommendations

1. Hardware / Operating System

I would recommend buying a Raspberry PI 4 or 5 and running the PI as a 24/7 server in your home network. This will give you the most cost-effective, reliable hardware possible. Operation with LAN (I would not recommend WLAN!) and “ssh” is sufficient. Personally, I would not set up a Windows-based device for this purpose (nor do I describe it)!

2. Software

• currently the Raspberry OS is based on Debian 12 (Bookworm)
• I would recommend the OS Lite 64-bit
• You need "openssl", which is available in the standard PI OS

3. additional Software

Since the SSL implementation is so closely linked to DNS mechanisms, I would also recommend a DNS resolver. Recommendation: Technitium! If PI-Hole & AdGuard fans are now shaking their heads, please watch this video:
