- STEGO & CYPHERELLA:
- A Cypherpunk Goddess Presents Us With Digital
- Fruit From Her Tree of Knowledge
- by
- Sandy Sandfort
-
- Cypherella is an ace software developer who has unleashed a subversive
- program called Stego, a different kind of encryption software that works
- because snoops can't even tell that you are using encryption software.
-
- How's it work? Let's say Slick Willie wants to hide his voluminous
- Little Black Book where no one can find it. If he puts it in an
- encrypted file on his White House personal computer, anybody who looks
- at the files on his hard disk can tell that he is trying to hide
- something, and by today's unfortunate "if you have something to hide,
- you must be guilty" standards he'd catch hell from the press. Enter
- Stego.
-
- The Stego program uses steganography, a method of disguising messages
- within other media. What that means, in practical terms (so Prez can
- understand) is that he can camouflage his secret Little Black Book
- inside something innocuous: one of Hilary's Vogue pictures scanned into
- a Mac PICT file would do nicely.
-
- Every picture stored on a computer is made up of pixels (picture
- elements). Depending on how many shades of gray or hues of color you
- want to have, a pixel can be expressed using 8, 16, 32 or even more
- bits. If the least significant bit is changed, the shade of the pixel
- is altered only one-256th, one-65,000th or even less. No human eye
- could tell the difference.
-
- What Stego does, is hijack the least significant bit to store only one
- bit of a secret message or file. Because digitized pictures have lots
- of pixels, it's possible to store lots of data in a single picture.
-
- But what if Hillary also has a copy of Stego? (She might want to hide
- her Little Black Book too, you know.) Bill could get busted. And then
- he'd really catch hell. Bill should first use a standard encryption
- program (like Phil Zimmerman's "Pretty Good Privacy") to encrypt his LBB
- before he Stegos the PICT file.
-
- Pretty cool, huh? Bob Packwood would've paid thousands for it. But
- because Cypherella wants you to have Stego, she is offering it as
- shareware. You get it for free. If you like it, you can send her a
- registration fee of $15. For that you'll get her latest updates plus
- special features and other valuable goodies.
-
- Software this great could only come from a wicked cool cypherpunk
- goddess like Cypherella. Also known as Romana Machado (and sometimes
- "Mistress" Romana, Katrina, or just plain Kate), she's an avid reader of
- science fiction, and has tried everything from ballet to Trekkie fandom;
- from drug research experimentation to medical research; from singing in
- baroque choral groups to posing for Playboy (November 1985). When she's
- not writing cunning encryption programs, she keeps herself busy as a
- software consultant, a model, and sometimes movie extra. She's designed
- and made black leather wrist braces to prevent or alleviate carpal
- tunnel syndrome.
-
- It's only natural that she would eventually hook up with the
- Cypherpunks. This self-mockingly-named group vigorously promotes the
- use of strong encryption to preserve personal privacy and freedom. It
- includes some real hotshots in mathematics, cryptography and computer
- science. Yet only a dozen or so of the several hundred Cypherpunks have
- actually worked on cryptographic projects. Of those, only Cypherella's
- Stego and a small handful of others have actually been finished.
-
- Stego was written for the Macintosh. PC and other versions may soon be
- available. To get your copy of Stego, you can FTP it from:
- sumex-aim.stanford.edu, in the info-mac/Recent directory as
- stego-10a2.hqx
-
- To get Stego on a Mac disk, send $15 to: Romana Machado: 19672 Stevens
- Creek Blvd., Suite 127, Cupertino, CA 95014.
