Encryption – How to Set Encrypted Home Passphrase


I just reinstalled Ubuntu, Natty. I set to use encrypted home, but once the system was running, I was asked to define the encrypted home passphrase. Out of haste, I skipped that, but now I want to define the passphrase but I couldn't find out how (despite how trivial this sounds).

I set my /home to a specific partition, so I may reinstall Ubuntu without losing my data whenever I need it, and I guess this is the passphare that I'd need to supply to recover my data on a new install, am I right?

Please, how can I define/change my passphrase?

ecryptfs-unwrap-passphrase ~/.ecryptfs/wrapped-passphrase 

The information you missed when you skiped was:
