Michael,
I checked out the article you mentioned. The Hashing won't work
because they are all one-way. And so I would actually need to store the
hashed password and/or the password itself in the application! And the code
at the bottom of the article which takes you step by step thru the
encryption methods is the same as what I've done in Pascal as per my
previous message. This article gave a better overall description of the
processes involved and I wish I had seen this earlier as it might have
shaved an hour or so off the time it took me to figure this out but in the
end it's exactly the same.

Subject: RE: Bytes, strings, and streams
Robert,
Look at this article it covers encrypting strings and moves onto
streams:

sp?frame=true
I spent a good while looking at cryptography in .NET but as you have
found most of it relates to processing large streams. Simply encrypting
a string is called hashing which is much easier to do. In fact most the
cryptography examples I looked at created a string hash to merge into
the encrypted streams, I just didn't realise I was already doing the
string encryption I needed, doh!

> Actually I am using NET and the algorithms I'm trying to use are
those provided by the clr. It seems to have available just about
anything I might need except as I said they all work with a MemoryStream
and byte variables. I tried typecasting but that didn't seem to work
and I don't know if I can substitute a different stream type...but I'll
give it a try and see what happens. One thing though, it seems a
terrible waste to use a stream just for a single string of perhaps 8
chars, but I haven't had any luck finding any specific string handling
encryption routines...good ones...that can be used in NET except for
paid libraries.
