transparent home directory encryption

#1 I'm very new to the ubuntu home directory encryption or rather ecryptfs folder encryption. I read about the same within Dustin's blog & tried implementing it. Problem or query is my home directory is encrypted & has a www folder ...

I'm curious to know more about the default ubuntu home folder encryption. I encrypted my drive with the live cd when I was installing ubuntu, and it didn't tell me anything about the encryption scheme! I want to know how many...uh...bits? the encryption has? and the encryption algorithm (the only one I know of is RSA).

I'm a bit of a newb at encryption so bear with me.

Question: Can I create an encrypted directory with ecryptfs that exists outside of my home directory, which uses the same decryption credentials that my encrypted home directory uses?

Here's the situation:

Code: /dev/sda1 (SSD): / /dev/sdb1 (HDD): /home /dev/sdb2 (HDD): /var and /tmp The above works fine, but I have 80GB free on /dev/sda1 that I'd like accessible from my home directory

I set up a friend with 12.04 and he forgot his password. I encrypted his home directory and I have written down the encryption passphrase during the first boot. If he changed his password after I wrote down the encryption passphrase during the first boot is this original encryption passphrase of any use?

I am having issue with my encrypted ecryptfs home directory after I log out and log back in. The home directory won't auto mount and I tried to execute "ecryptfs-mount-private" manually and it does not seem that it does anything.

I have to reboot the box to see my home directory again.

Any idea what is going on and how to fix that? Let me know if you need any additional logs.

Thanks

What I am trying to do is bind: /home/username/Dropbox/Documents to /home/username/Documents on startup.

I have my home folder encrypted. If I change my login password with the passwd command, do I need to change anything else for the encrypted home folder to still work properly?

Also, if I need to access the encrypted directory manually later on (from a liveCD, putting the HDD in another machine, etc.), do I need to use the login password or the passphrase to get into it?

Hi. So I've just installed Arch after using Ubuntu 11.04 and it turned out that U had my home file encrypted (which is weird, because I specificly ordered it not to do it when installing it). But anyway.. I've installed Arch and wanted to replace my Arch's /home with the seperate /home partition I've had (I didn't specified it when installing).

been looking all over and can't seem to find an answer for this...

i recently re-installed ubuntu and enabled an encrypted home directory upon installation.
