That's It! Part 5 of 5
Dropbox has finished installing and you're all setup and ready to go. Thanks for using dropbox. We hope you enjoy it.
CHECK Open my Dropbox Folder NOW.
Click “Finish”

A new folder $HOME/Dropbox is created and you will see messages that it is synced with the Dropbox Server. It has a Photos and Public Directory along with a Getting Started PDF Document. The Dropbox applet starts automatically with KDE-4.5.5


Any Personal Files that are confidential should be encrypted before they are synced with the Dropbox Server. First, setup your Dropbox account and make sure it works. Then, you can use the following commands on a folder before you copy it to the Dropbox folder. In this tutorial assume there is a folder named $HOME/Dropbox that gets synced with the Dropbox Server and the folder with the files to be encrypted called $HOME/Backup

$ cd $HOME
Be sure you are doing this as a Regular Non-Root User!

$ tar czf <Backup-Date>.tar.gz Backup
I use the date of the backup as file name <Backup-Date>, but suit yourself.

$ openssl enc -e -aes256 -in <Backup-Date>.tar.gz -out ./Dropbox/<Backup-Date>.tar.gz.enc
enter aes-256-cbc encryption password: <Password> <ENTER>
Verifying - enter aes-256-cbc encryption password: <Password> <ENTER>

$ shred -u <Backup-Date>.tar.gz
This is a way of shredding files and removing them. You still have your Backup Folder to worry about.

NOTE - A really clever way to get passwords is to use Jesse Smith's idea from the Distrowatch article “Head In The Clouds”. It involves getting an MD5SUM of the *.tar.gz and using only the first 16 characters of the MD5SUM as the OpenSSL Password. You keep track of the passwords by putting them into a text file. You can keep the password file safe by using a TrueCrypt Volume, EncFS Encrypted Folders, or a Vim Password Safe-type file.

To decrypt the file

$ openssl enc -d -aes256 -in <Backup-Date>.tar.gz.enc -out <Backup-Date>.tar.gz
enter aes-256-cbc decryption password: <Password> <ENTER>
