in the US, I downloaded the export version
of Strip and to my surprise, I found out that the basic encryption is
a Palm OS call to EncDes() ... which I could find no reference to at
all in the Palm Reference Guide. So
1) does the US version of Strip has stronger encryption that is not
part of the Palm
I decided to follow the advice. I implemented the very famous (and simple)
sysmetric-key encryption scheme (too bad I forget the name of it). It is
theoreticaly unbreakable (in ideal conditions) if the key is long enough and
the data is truely random.

I found function EncDES in encrypt.h in the Core include directory. Has anyone
tried it? Does it work at all? I couldn't find any reference on that, not
even in the Palm OS Reference.pdf or any book I have. Is that function left
intentionly hiden from public use?
Thanks.

... And I just found an old post (Sun Oct 3, 1999) by
Ken Krugler who says that EncDES is only conditionally
supported. Here's
, then I'm not sure you can assume it
to be in *any* version of Palm OS. And if it is, for all you know,
EncDES is someone's code word for Erase the storage heap.
Don't use undocumented functions. It's as simple as that. If you
want encryption, there are other, supported avenues available to you

officially in US considered a US device?

Do you mean supported by PalmOS? What are those then?

I don't keep records on those particular solutions. However,
performing searches on the standard sites (google, sf.net, the forum
archives) will reveal many options to you.

you really want to know is whether or not
a Japanese branded Palm OS device contains EncDES in
the ROM, I don't know, but it probably does not. You
could easily get a Japanese ROM and test it.
However, it would be better to heed Keith's advice and
not use unsupported functions which could disappear
I thought there are some solutions from PalmOS (the company) and supported by
PalmOS (the company). I haven't found any.
Before I use any third party or code my own, I always check the solutions made
available by PalmOS.

BTW, I'm currently double-checking on this one. EncDES (and two
other functions I just noticed
. But it looked for a moment there like you
were going to go ahead and use EncDES. I just wanted to head that
off. Please keep it near the top of your stack that undocumented
functions are neither solutions nor supported.
