Why the cryptographic key was not provided at ubuntu 12.04 first run?

Question

So I installed Ubuntu 12.04 a few days ago and strangely I missed the part where we choose to encrypt home folder.

However I already ran the commands on this question (How to check if your home folder and swap partition are encrypted using terminal?) to check if home folder and swap partition are encrypted and they are.

So why is that Ubuntu did not provide me the cryptographic key the same way it happened when I installed Ubuntu 11.04???

Thanks @ObsessiveFOSS for reminding me, some of this problems were about Lubuntu, which meanwhile I uninstalled in order to use default Ubuntu, and I forgot about some of the previous questions. I am now marking best answers to close the questions :) — Neptunno, Jun 04 '12 at 23:39

Well, I still don't know why the passphrase for home folder encryption was not provided at first run, anyway, with a simple command in terminal, it is possible to get this passphrase.

ecryptfs-unwrap-passphrase

This is useful if it is ever needed to make a manual recovery of the data present in encrypted home folder, as described here:
