How Encrypted is it?

[susequint]

I just checked the box for disk encryption and installed Tumbleweed. Does anyone know how encrypted it is?

I didn't/don't see any indicators of key length or anything else in Yast Partitioner or Gparted. I'm just curious if it's strongly or weakly encrypted. I gave it a nice long password, but don't really know how safe I am.

You can get some information (perhaps not as much as you would want) with

# cryptsetup luksDump /dev/sdXn

where you change that the the device name for the encrypted partition.

I think the default is to use AES with a 256 bit key. Your passphrase is hashed and used to encrypt the AES key, though I'm not sure of the details. Also

man cryptsetup

might have useful information.

I think that command tells me the defaults are not watered down and weak.

Thank you nrickert!
