... And I just found an old post (Sun Oct 3, 1999) by
Ken Krugler who says that EncDES is only conditionally
supported. Here's an excerpt:
On a related topic, while EncDigestMD5()
should always be available on 2.0 or later
versions of Palm OS, note that EncDES()
(also added in 2.0) is conditionally
implemented - if you're running on a non-US
device, then calling that trap generates a
"DES Not Supported" fatal alert. To check
for the presence of this support, you'd
need to use FtrGet, as in:
UInt32 attributes;
Boolean hasDES;
hasDES = (FtrGet(sysFtrCreator,
sysFtrNumEncryption, &attributes) == errNone)
&& ((attributes & 0x01) != 0);
