## Encrypting information being sent to MS SQL database over the internet.


I have a software application written in c# that accesses a database over the internet.  I need a way of encrypting the information being sent back and forth between the application and the database.  We also have a web application running off of the same database, and for this we are using an SSL certificate.  Is there anyway to incorporate this certificate into the application?  I would prefer not to encrypt the information in the database, just the transmission.

Thanks for your help.

How is the information being sent/recieve?. Remoting? proxy objects?.. or are you opening a db connection to a server over the internet?

Check this out: using SSL to secure communication with SQL Server 2000:

If the server is certified and running your app then yes you can run off of its certification. But it depends on the certificate as to how you go about this. Another option is to put another application on the SQL server that acts as an intermediary with your application, and then you can simply throw a plugin that uses Public or Private key encryption (whatever you want) on to it. Just make sure you don't use anything labeled as "Proprietary" just stick to what is tried and true, for example RSA.

Thanks for all your help.  The information is currently being stored at a hosting company.  They will not enable the encryption for me.  We are in the process of removing it from them, and placing it on a local server.  When this is done, (within the next couple of days) I will be able to attempt these methods.

If you are putting the database on a local server, you might not want to encrypt the transmissions at all if you KNOW that your firewall settings are strong and your network is secure. Encryption on a database connection will affect performance considerably, so I wouldn't do it unless I had to.
