I have a LUKS encrypted SSD and I would like to clear it and install a different Linux distro (Debian -> Ubuntu). I want to decrypt my drive and I tried to use:
cryptsetup luksRemoveKey /dev/DRIVE
This is the last keyslot. Device will become unusable after purging this key.
It got me worried so I'm here asking this question. Does this mean that the drive will be completely unusable or will the data simply be erased? If it will become completely unusable, how do I decrypt my drive?
