WTF is a KDF? A startling revelation from a French prison
Bruteforce of such random password is just not plausible and talks about KDF "weakness" is just a distraction. I think most likely it was evil maid attack.
Here are projects which try to mitigate some of evil maid attack risks:

https://safeboot.dev/

Installation with full-disk, two-factor encryption, secure boot, and TPM
Secure boot and TPM support (à la Mortar: https://github.com/noahbliss/mortar)
-
Complying with the future: Secure Boot and TPM unclocking
There are tools that look to be able to automate it: https://github.com/noahbliss/mortar/blob/master/docs/proxmox-install.md

Prevent backup of vTPM2.0 state?
I just went through the process of setting up new ubuntu VM's using full root disk LUKS encryption and auto-unlock via Proxmox's vTPM2.0 and UEFI ( via this extremely helpful resource https://github.com/noahbliss/mortar )
-
tpm2 + luks + ubuntu 18 setup?
I have used this project with Debian+proxmox and it's been working great. https://github.com/noahbliss/mortar but I did read the arch wiki a bit which helped my understanding.

What do you don't like about Linux? What is Windows doing better?
There's a project called "mortar" (as in, gluing all these bricks together) that was attempting to simplify this. Though it's lost steam, reading through it's simple bash scripts was a great place to start for me. This guide for Fedora also helped a lot.

Authenticated Boot and Disk Encryption on Linux
There have been a number of attempts to solve this problem, but the most complete appear to be Mortar (a project I head) and safeboot.dev
I highly recommend taking a look at either of these projects if you want be able to improve both your convenience through auto unlocking, and security through broadened scope of audit.

Best Evil Maid prototcol for Linux?
Check out mortar. It uses secure boot and TPM along with LUKS. The creator is super helpful and available on the telegram.

Mount encrypted volume at boot?
A more advanced approach would be something like mortar to chain-load signed stuff.

Will Proxmox be able to run Windows 11?
There seems to be a workable solution out there for 2.0: https://github.com/noahbliss/mortar/blob/master/docs/proxmox-install.md

Can I use Security Key C NFC as backup for 5C NFC if I use OpenPGP?
Instead, most people generate keypair(s) on an airgapped machine and write them to two Yubikeys. Or write subkeys to a single Yubikey and keep a backup in encrypted form. See https://github.com/drduh/YubiKey-Guide

Ask HN: Why does YubiCo need my private key?
I'd recommend using the Yubikey as a GPG smartcard[1]. The private key stays on the Yubikey. I also use it for ssh. But make sure you have a backup key or two, just in case the primary Yubikey gives out. FIDO2 and all other regular Yubikey functionality still works with it.

An Opinionated Yubikey Set-Up Guide
The excellent guide by drduh should be mentioned here: https://github.com/drduh/YubiKey-Guide — I've been using this approach for years to store my OpenPGP keys on Yubikeys and use them for SSH.
I don't generate my keys on devices. That lets me be flexible and keep backups, as well as use the same keys on multiple physical devices. Using a single yubikey is a bad idea, as you're bound to eventually lose it or break it. Hasn't happened to me yet in 5 years, but I expect it to happen.

GnuPG Private Key storage on YubiKey: Why are the private keys still present in my .gnupg/ folder?
See https://github.com/drduh/YubiKey-Guide . Also google for OpenPGP card specifications, they will answer your question

Got myself Yubikey and set it up for my password manager and email. What next?
Regarding GPG/SSH keys, there is a great howto: https://github.com/drduh/YubiKey-Guide

Some guidance from those who use their Yubikey to protect their SSH connections.
I'd be lying if I said I understood all of that. I'm definitely going to do some research ahaha. Someone else on this post sentence this like which they said was very good guide. https://github.com/drduh/YubiKey-Guide

When it comes to storing PGP keys what is the difference between a YubiKey and a standard USB key
When storing the key on a Yubikey, however, all you need is just the PIN in order to use the key. It can contain numbers, letters, symbols, etc. and can be quite long, so you can treat it as a passphrase for all intents and purposes. There are actually two PIN codes: one regular one, for a read access, and another administrative one, for write access for when you want to modify the gpg applet settings or the key on the Yubikey. There is also a limit to how many times in a row you can enter pins incorrectly, after which the gpg applet gets locked and the only thing you can do is reset it, erasing the PGP keys. See https://github.com/drduh/YubiKey-Guide for more information.
