ecryptfs is a POSIX-compliant enterprise-class stacked cryptographic filesystem for Linux. It comes standard with Ubuntu. This is probably the most painless way to protect your home directory in the event your computer is stolen. After you log in, either from a console or gdm, your home directory is available as always. Once you log out, your entire home directory (and all sub-directories) is encrypted (both filenames and contents). It works completely transparently.
encfs creates a virtual encrypted filesystem which stores encrypted data in the root directory and makes the unencrypted data visible at the mount point directory. The user must supply a password which is used to (indirectly) encrypt both filenames and file contents. This is a simple way to encrypt, for example, a thumb drive.
encfsctl is an administrative tool for working with EncFS filesystems.
gpg (OpenPGP) is an encryption and signing tool and is simple to use
$ gpg -c myfile
Enter passphrase: secret
$ rm myfile
$ gpg -d myfile.gpg > myfile
Enter passphrase: secret
$
It can't get much simpler
