Why not write an algorithm of your own?
If you want to go the world standard way then mail me personally. I
have done some heavy encryption work and I don't mind sharing
the code of some standard classes written by me.
The combination includes -
MD5 - (hashing)
RC4 (128) - (encryption)
RSA

Thanks for that suggestion. I'm out of the office today
but will examine it to see what makes it tick tomorrow, and see if I can use
something along those lines.
Appreciate your help.

It might not be insecure if you use it in the right way,
1. Make sure your key is random
2. Make the key as long as the message
3. Never re-use the same key
This will turn this cypher (a viginere with a feedback loop (?)) into a
One-Time-Pad which is proven to be unbreakable.

Thanks for the offer Nirav but I'm successfully using a variation of
Phil Scadden's simple routine. I've just added a simple checksum to it
so I can tell if it's been tampered with.
Cheers,

Brendon,
You don't say whether the data in your .dat file is sorted, or how many
entries you are likely to be expecting, or whether you're developing for
Win32 or Win16.
However:
If the records in the .dat file are unsorted and you don't want to lad the
