    Works both ways, plus it's really simple! :-)

    You could also just XOR the data and back again.. a bit more "secure" than
    above, but still fairly simple and easily broken. (Kid-sister scrambling unless
    you've got a secure channel to transfer the XOR chunk back and forth, AND are
    able to generate a new key each time, AND those keys are identical in length to
    the original data) It'd probably work to keep grep from finding your string
    though.
