I'm not an expert, but 3 options I can think of are gnupg (you would need
your keys to unscramble the file) or a password protected zip, or use
TrueCrypt and create a file based encrypted virtual drive, then copy
whatever you want to the drive, unmount the drive, email it to yourself and
use truecrype on the other end to mount the drive and get your stuff...
might want to zip the virtual drive but encrypted stuff tends to compress
