Tails Live CD checksum

Question

If you made USB stick in Linux with the official method, then you first insert the USB stick of Tails Live OS, then run "Disks" from the menu, you can see the USB stick, click it and at the right side of window shows the paragraph about the volumes, click the "play" icon under the "TAILS 1.0.1" partition, then you browse the USB stick by your file browser manager, you can find those files:

If you make the iso in Windows, you just need to open the directory in USB stick.

So do you have the same MD5Checksum? My downloaded ISO file are different with the checksum, what's the files inside? Is that safe to use this USB stick made by this ISO?

Answer 1

As @user194 says, it is difficult to know quite what you are asking. But assuming that you are asking about the unpacked files versus the iso, then I think it is reasonable to say:

1. If you verified the identity of the ISO using the methods described on the Tails site, then the ISO is safe (within the bounds of safety of anything cryptographic!).
2. If you created the USB bootstick using the methods described on the Tails site, and assuming that your machine is not already grossly compromised, then the USB version is safe to use.
3. There is absolutely no reason to expect that the concatenation of all the individual files unpacked from the ISO would give the same MD5 hash as the ISO itself. In fact, if they did, it is then that one would begin to suspect that something was seriously wrong!
