How to mount LUKS encrypted file?

Question

I have a file (about 13GB).

When I execute the command file "filename" in terminal, It shows tails_filesystem: LUKS encrypted file, ver 1 [aes, xts-plain64, sha1] UUID : blahblah

And, when I mount in FTK imager for viewing filesystem, It shows Unrecognized file system [unknown]

I know LUKS passphrase for this file dump.

But I don't know how to mount this file dump for analysing.

Google contains only a few methods of encrypting volume by dm-crypt... :'( (In addition, I tried to analyse with freeOTFE & librecrypt. This failed.)

How can I see files in LUKS encrypted filesystem dump??

Solution

Be sure dm-crypt kernel module is loaded.

modprobe dm-crypt

Then I would suggest:

cryptsetup open --type luks /path/to/dump desired-name

This should create a device /dev/mapper/desired-name which you can then mount as used to.

mount /dev/mapper/desired-name /mnt

I'm not sure if this works for a dump. But it's quite possible.
