The lifehacker way: http://lifehacker.com/software/top/geek-to-live--encrypt-your-data-178005.php#Alternate%20Method:%20OpenSSL

"That command will encrypt the unencrypted-data.tar file with the password you choose and output the result to encrypted-data.tar.des3. To unlock the encrypted file, use the following command:"

openssl des3 -d -salt -in encrypted-data.tar.des3 -out unencrypted-data.tar
tar zcf - foo | gpg -c --cipher-algo aes256 -o foo.tgz.gpg
