Access Data

[James B]

I have been asked to write a windows app that will reside
outside our organization that can Read/Write data that
will be on one of our servers. Since I have never done
this before I'm not sure how I can securely access the
data. I have used web services to send and receive
datasets over the Internet but not encrypted. Any help
would be great.

Hi,

Perhaps look into implementing web services and SOAP over
port 443 (SSL) and let the web servers themselves handle
the encryption over the line.

Unless there is a distinct need to encrypt the data
first, send it as a chunck, and then decrypt - this will
most likely be the easiest method.

Check out the book "Programming the Web with VB.Net -
ISBN - 1-59059-027-9" for good examples.

good luck.

Hello James,

Thanks for your post. I'd like to share the following information with you:

1. If you are using web service to send/receive data, as suggested by inzo,
you can call it using SSL. I believe the following MSDN articles are
helpful:

2. If you are writing a windows app, could you please tell me how you share
the file on server, using FTP?
I believe that you can configure IP Security (IPSec) to encapsulate
Internet Protocol (IP) packets and encrypt them. Please refer to the
article below for detailed information:

Please feel free to let me know if you have any problems or concerns.

Have a nice day!
