It is because the root file system is also encrypted, so the key is safe. The root file system is decrypted during the initramfs stage of boot, a la Mikhail's answer. I have another entry in the /etc/crypttab file for that: crypt1 UUID=8cda-blahbalh none luks,discard,lvm=crypt1--vg-root and I describe setting up that and a boot usb here Add Linux Unified Key Setup (LUKS) by davidhicks · Pull ...

The key slot state can only be ENABLED or DISABLED, so I've made it an enumeration as suggested. ...

I have the same decryption problem with full LUKS encryption. It does take about 30s for me which is way too long. Maybe I’ll try that solution when I get home. I tried to create completely new LUKS headers (for all partitions?!) once but they did not work when I tried the decryption during boot (pw not accepted). linux - LUKS passphrase doesn't work - Unix & Linux Stack ... If there is corruption in the LUKS header (more than just a single byte), it's pretty much impossible to recover. The LUKS header does not have a checksum for its key material, so - if it's damaged in any way, the cryptsetup luksDump will look same as always, but your passphrase simply won't work anymore. cryptsetup(8) - Linux manual page - Michael Kerrisk
In this example, we are deleting the key from LUKS slot#2. For this, you have to enter the LUKS key for any one of the slots. This is only as a validation before it delete the Key from slot#2. # cryptsetup luksKillSlot /dev/sdb1 2 Enter any remaining LUKS passphrase: As you see from the following luksDump output, the key in Slot#2 is now erased.
For LUKS operations that add key material, this options allows you to specify which key slot is selected for the new key. This option can be used for luksFormat, and luksAddKey. In addition, for open, this option selects a specific key-slot to compare the passphrase against. Encrypting containers (or partitions) with Cryptsetup and… Linux Unified Key Setup (LUKS)LUKS provides a standard on-disk format for encrypted partitions to facilitate cross distribution compatability, to allow for multiple users/passwords, effective password revocation, and to provide additional security against low entropy attacks.

Actually LUKS does not encrypt the MasterSecretKey with a password but with a key, generated with a PBKDF. A similar approach is used by GPG when you send a message to a set of distinct recipients. This is usally know as KEM/DEM paradigm: Key Encapsulation Method/Data Encapsulation Method and it is the standard method when you use public key to encrypt something.
However, immediately a valid platform key is written into PK (in practice, this would be an X.509 public key, using a 2048-bit RSA scheme), the system (aka, 'platform') enters user mode. 0013955: [abrt] xorg-x11-server-Xorg: Xorg server crashed… backtrace (523 bytes) 0: /usr/bin/X (xorg_backtrace+0x55) [0x555d776e5655] 1: /usr/lib64/xorg/modules/input/synaptics_drv.so (0x7fe160625000+0x4f28) [0x7fe160629f28] 2: /usr/lib64/xorg/modules/input/synaptics_drv.so (0x7fe160625000+0x6c22 … TimeDicer - Free Secure Local and Remote Windows Backup and…
dm-crypt/Device encryption - ArchWiki - Arch Linux The most notable expansion was for the Linux Unified Key Setup (LUKS) extension, which stores all of the needed setup information for dm-crypt on the disk itself and abstracts partition and key management in an attempt to improve ease of use. Devices accessed via the device-mapper are called blockdevices. Ubuntu Manpage: cryptsetup - manage plain dm-crypt and ...
