(Bash) Encrypt your /home partition - Dorgendubal

Sun, 28 Jun 2009 10:51:04 UTC

Ideal if you have a laptop. If someone steals it, he will not be able to read all your mails and documents with precious information (about passwords, accounts, credit cards, private stuffs, etc...). This snippet is considering that you are using Ubuntu as OS and you already have a dedicated partition for home (/dev/sda5 in my example). * Steps 1-3 are pre-requirements. * Steps 5-7 encrypts the partition and formats it as ext3 (make sure that you have a backup of your home somewhere!!!) * Steps 10 and 13 are not commands but lines to be added (or modified) in the editing files (Step 9 and 12). You have to be familiar with /etc/fstab to understand it. * Other steps are for configuring your system such your home partition gets automatically mounted on startup (you will be prompted for password during boot). Enjoy security!

* Resized images are generated into TARGET_DIR. * Change the resolution (800x800 in my example) and quality (80) as you want. * The command keeps the image's proportion. 1600x1200 will be converted into 800x600, 1200x1600 into 600x800. _Notice_: the command does also resize images in sub-directories but put them in the same target directory (overwrites any existing file).
