    <p>We would like to use SQL Server Encryption to encrypt a couple of columns within our databases. We also need to transfer data between our production and test environment. It seems like the best solution would be to use the same master key, certificate, and symmetric key on the production and test servers so that I could encrypt or decrypt the columns in either production or test environments with the same results.</p> <p>So far I have tried using the same create script in both environments which did not work. It encrypted on one server but did not decrypt on the other after data was transferred to the other server:</p> <pre><code>use &lt;database name&gt; CREATE MASTER KEY ENCRYPTION BY PASSWORD = &lt;password1&gt; use &lt;database name&gt; CREATE CERTIFICATE &lt;certificate name&gt; WITH SUBJECT = &lt;certificate subject&gt; use &lt;database name&gt; CREATE SYMMETRIC KEY &lt;key name&gt; WITH ALGORITHM = AES_256 ENCRYPTION BY CERTIFICATE &lt;certificate name&gt; </code></pre> <p>And I have tried creating the master key, certificate, and symmetric key on one server and then restoring it on the other which doesn’t seem to <em>create the key</em> and therefore doesn’t work either.</p> <pre><code>use &lt;database name&gt; OPEN MASTER KEY DECRYPTION BY PASSWORD = &lt;password1&gt; BACKUP MASTER KEY TO FILE = 'c:\masterkey.txt' ENCRYPTION BY PASSWORD = &lt;password2&gt; use &lt;database name&gt; BACKUP CERTIFICATE &lt;certificate name&gt; TO FILE = 'c:\Cert.txt' WITH PRIVATE KEY ( FILE = 'c:\Key.txt' , ENCRYPTION BY PASSWORD = &lt;password3&gt; ) use &lt;database name&gt; RESTORE MASTER KEY FROM FILE = 'c:\masterkey.txt' DECRYPTION BY PASSWORD = &lt;password2&gt; ENCRYPTION BY PASSWORD = &lt;password1&gt; use &lt;database name&gt; OPEN MASTER KEY DECRYPTION BY PASSWORD = &lt;password1&gt; CREATE CERTIFICATE &lt;certificate name&gt; FROM FILE = 'c:\Cert.txt' WITH PRIVATE KEY (FILE = 'c:\Key.txt', DECRYPTION BY PASSWORD = &lt;password3&gt;) </code></pre> <p>How can I encrypt on one SQL Server and decrypt on another?</p>

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.
