Default Table encryption

If I enable encryption for a table, what kind of encryption is used?

The standard encryption - I think that's Blowfish with some standard key. At
this point (with this level of encryption), people can't read your encrypted
files with notepad, but anyone can read 'em with the EM.

If you want it encrypted uniquely, you need to write your own encryption
engine, which basically involves (at its simplest) getting hold of an
existing encryption engine and changing the key to something proprietary.
But, once you add this custom encryption engine to your nxserver.exe, any EM
can still read it, because the nxserver it uses can read it. So you need to
also make access to your nxserver.exe secured.

HTH,

It should be pointed out that this type of table encryption will fit
single-exe applications very well.
