Hello,
there are few options how to detect a LUKS container:
- use 'cryptsetup luksDump' on your device. It will fail, if it's
not a LUKS container.
- If you have a dump, you can also use the 'file' command
Or the sophisticated one :-)
- Look at the first few bytes of your partition/dump and check, if
it contains the magic header "LUKS"
'sudo head -c 128 /dev/yourdevice | hexdump -C'
It should look like
00000000 4c 55 4b 53 ba be 00 01 61 65 73 00 00
00 00 00 |LUKS....aes.....|
00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

00000020 00 00 00 00 00 00 00 00 78 74 73 2d 70 6c 61

Hi,
I've read
the FAQ (but can't guarantee I didn't miss something). In the
warnings sections about the Ubuntu installer I read "... (it
is very easy to recognize a LUKS container)..."
I don't
actually need to know, but I'd like to know how this is done.
I didn't find the answer in the FAQ, didn't find it using
Google and didn't find it on Stack Overflow.
