I happen to have solved it now, I ended up using the Delphi LockBox
implementation of 3DES and found on CodeProject an implementation that
was compatable with it for C#.

Hurrah!

Google has been helpful and I did find a whole host of blowfish and
other implementations, unfortunately non seemed to be cross platform
compatible between desktop pc and windows mobile. I also struggled and
didn't particularly have time to understand the IV concept and really
just wanted something fairly quick and out of the box to just work with
a key.

So what you're saying is you don't want to learn how to use the cipher
so you want something that seems plausibly like a solution. Mmm that
blue button!

Also to those "posters" suggesting I use other languages, if I could I
would have. I know a few languages very well, and can obviously fairly
quickly pick up others. It is fairly pointless to suggest that I use
other languages when I am being specific in my need for solutions
between these two, don't you think?

Language wars are what make usenet great. If you don't like it you can
get out of usenet. :-)

FYI, I am using Delphi on the PC as it is a large program that has
already been produced by software engineers past, and I am just
updating it, not least to say that it is a very good language to use
and certainly the forerunner for all MS's .NET stuff (which one of the
orginal Delphi programmers went over to MS to help create).
I am using C# as there is a RAD need for a Pocket PC equivalent of the
PC program. Doing this in older embedded Visual C++ or some other
alternative would just hold things up.

Here's a random totally isolated thought. MVC. :-) Your GUI and your
guts can be programmed in two completely different langs for all it
matters.

C may be "better", faster and closer to the hardware, but I couldn't
really care less as I am not working close to the hardware I am working
at an application level. People can scoff at Delphi/Pascal, .NET, Java,
all they like the fact is that they are easier and quicker to use at
higher levels and produce results quicker at these levels. Perhaps they
aren't as fast when executing but with computers as quick as they are
these days who really cares other than specialists for specialist
needs?

It's thinking like that that enables people to think Vista is a
valued-added proposition.

Sorry for the rant but I found some of the cynicism irritating!

Well maybe we have good reason to object to random buzzword bingo
advocation?
