    <p>I actually had a similar requirement. I addressed it by taking my connection string and encrypting it using the Rijndael encryption logic (check it out in System.Security.Cryptography). It's very easy to use. A friend of mine has been attempting to crack this for the past 19 months, using a series of Rainbow tables - yes, he has way too much time on his hands - and has told me that "our solar system will probably go dark before I can get in." I laughed. Way too much free time.</p> <p>I simply took my connection string, which I do store in an XML file (so I can change it out if needed) and encrypted it. My app, as part of its initialization process, reads in this value - decrypts it - then, connects and opens the database.</p> <p>Something like "I am a piece of data that is to be encrypted" ..... once encrypted ends up something like ..... "V27AsTNsJA+BEwoGR2PbiZum5puwiLbfMa41ens8r8sSiEnn6FiT+k8ImEft Qba8ziCpie94s3bEwcPekqRfhO1Noc8lVeERyezmtqN9/0ZgmzJbNbl/3emTLLfb0Qpj" .... which obviously isn't going to be very useful to someone trying to break in.</p> <p>It's worth pointing out that even with a lowly 128-bit encryption (this supports 256-bit also) remember that there are 2 raised to the power of 128 possible values, or 3.4 e+38. Think what a huge number that is:</p> <p>340,000,000,000,000,000,000,000,000,000,000,000,000</p> <p>If you attempt to crack this, for example, at the rate of 1 trillion attempts per second (1,000,000,000,000 / second) it could potentially take you 3 million million million years to get it. Of course, you might get it on the first guess .... probably not, though.</p> <p>A 256-bit key is 1.15 e+77 and a 512-bit key is 1.34 e+154 possible values.</p>

    2. CODuring the initialization process, you say it decrypts the connection string. Is this decryption key also stored in the app or is it typed in by you at runtime?

    3. CO@jskaggz - I honestly can't imagine trying to type a key or IV ... you'd make allot of errors doing it (or at least I would). It's a part of the application itself, but it's obfuscated in case someone tries to reverse engineer the app to get it that way. There's actually several ways of handling this issue - mine allows for me to remotely "push" new crypto to the app because the encryption is also used for communications too, and swapping out crypto makes it all but impossible for anyone to penetrate security.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
