+
+About
+=====
+
+This is a short howto on changing the harddrive passphrase on your ubuntu system.
+
+
+It was successfully tested on
+* Ubuntu Gutsy
+
+Where is your encrypted partition?
+==================================
+
+* Have a look into '/dev/mapper/'. There should be an entry called '..._crypt', usually its 'sda5_crypt'.
+* Whenever I use "sda5" later on, replace it by whatever '..._crypt' says in your setup.
+
+Changing the passphrase
+=======================
+
+* You can't change the passphrase directly, add another passphrase and remove the old one.
+* Passphrases are stored in "slots". So your first password is in "slot 0", the second will be in "slot 1" and so on.
+* Be sure *never* to delete your *last passphrase*, or your data will be inaccessible forever.
+
+Adding an additional passphrase
+===============================
+
+* Open a 'terminal', and type:
+
+::
+    
+    cryptsetup luksAddKey /dev/sda5
+
+* enter the current passphrase
+* enter the new/additional passphrase
+
+Removing a passphrase
+=====================
+
+ *Warning:* Do NOT delete the last available passphrase, or your data will be lost forever!
+
+* To delete the first passphrase (BE SURE THERE IS A SECOND ONE! TEST THE SECOND PASSPHRASE BEFORE DELETING THE FIRST!):
+  cryptsetup luksDelKey /dev/sda5 0
+
+* To delete the passphrase in the second slot (BE SURE THERE IS STILL ANOTHER PASSPHRASE PRESENT!):
+   cryptsetup luksDelKey /dev/sda5 1
