Well, there are a bunch of books out on PGP, which they can read. And there
are already some good FAQs out on the basics of cryptography--surely
concise enough and yet detailed enough to warn folks away from some
basically flawed programs.

But just how far can one go? Some people just won't be taught, despite the
several very-accessible books on PGP and crypto. So?

And I don't really think there's a problem. Just how many of these "Snake
Oil" crypto programs are people really _buying_? And does it matter if they
buy a reasonably-competent program (*) like "DiskLock" instead of using
3DES or one of the good disk encryption programs?

(* By "reasonably competent" I mean not "snake oil," and roughly able to do
the job for which it was intended. Many people just want casual-grade
crypto, to stop casual attempts to look at what they've written. We may
disagree with them, but, hey, it's their choice. I maintain that these
people are unlikely to read something called "The Snake Oil FAQ.")

To coin a phrase, you can lead a person to strong crypto, but you can't
make him drink.

At some point this become YACB (Yet Another Crypto Book). If you and others
want to donate time to help educate the (small, I think) class of users who
won't read the PGP books, or the PGP articles in the magazines, and yet who
you think are smart enough...blah blah...well, go ahead and write such a
thing.

(BTW, Schneier has a book out on "Security for the Macintosh," a kind of
watered-down intro to crypto and security....he makes the points a "Snake
Oil FAQ" might make...again, I think this is an overcrowded market.)

Wouldn't arguments out of the standard textbooks have been just as
effective, and perhaps even more "credentialled" than words from a FAQ? I
hope you are not expecting that a FAQ would have the precise magic words
dealing with your programmer friend's situation? At best, it would contain
seom reworded arguments out of the well-known textbooks.

I just don't see the point.

But if it keeps folks busy, and happy, I guess it's harmless. (:-})
