luks recovery

hosszufa12

Hello
I have a drive which was encrypted with LUKS, using the cryptsetup luksFormat /dev/sda1 (no other options, just the defaults) under linux. Then when i wanted to format a pendrive, i accidentally formated that drive instead of my pendrive. But i only wrote a label.
The LUKS faq says that for decryption, the password, the keyfile and the encryption method need to match, and that the keys are stored from the 208th byte, to the 592th byte, each key being 48 bytes. The label is 512 bytes. So as far as i can tell, the last key should still be there, because 592-512>48.
So if i know the encryption algorythm, i have the password, and i have the key, would it be possible for me to get back my data? If yes, then what exact steps do i need to perform for that to happen?
Im currently on dragonflybsd and it does have luks support so i think i can fix it from there.

Install the cryptsetup utility on your DragonFlyBSD system if it's not already installed.
Run the following command to unlock the LUKS-encrypted drive:

cryptsetup luksOpen /dev/sda1 encrypted_drive
Replace "/dev/sda1" with the device path of your encrypted drive. "encrypted_drive" can be any name you choose to give to the mapped device.

Once the drive is unlocked, you should be able to access the decrypted data at the device path "/dev/mapper/encrypted_drive". You can mount this device and copy your data to another location.

Note: The success of data recovery depends on the state of your encrypted drive after the label was written. If the data on the drive was modified or overwritten, it may not be possible to recover all of the data.
