My experience with Adobe Flex has been fairly limited, however I have found this package which should allow you to introduce AES encryption into your application. Please check out the <a href="http://code.google.com/p/flex3cookbook1/downloads/list">AES Encryption Code Base for Air and Flex 3</a> in the <a href="http://code.google.com/p/flex3cookbook1/">Flex 3 Cookbook</a>!</em></p><p>I&#8217;ve been pretty busy with work lately, but it has been very interesting. The past couple of days I&#8217;ve been working with the <a href="http://en.wikipedia.org/wiki/Advanced_Encryption_Standard">AES</a>/<a href="http://blogs.msdn.com/shawnfa/archive/2006/10/09/The-Differences-Between-Rijndael-and-AES.aspx">Rijndael</a> to encrypt sensitive user data in the application I&#8217;m currently working on. It has been pretty interesting and has proven to be quite a learning experience.</p><p>The main reason it has been a challenge is that some of this data that we&#8217;re encrypting needs to be decrypted and searched through for reports. We have already decided on using <a href="http://www.microsoft.com/sql/technologies/reporting/default.mspx">SQL Server Reporting Services</a> (which I haven&#8217;t worked with before) to handle these reports, however there was the question of decrypting these fields through SQL Server. Luckily we should be able to <a href="http://msdn.microsoft.com/en-us/library/w2kae45k(VS.80).aspx">create CLR User-Defined functions</a> to handle this.</p><p>I have also spent some time cleaning up the solution. This particular project has been going on for the past year and a half (or so) and has had quite a few hands touching it. I went ahead and organized the projects in the solution and fixed the dependency problems that everyone had been <em>just dealing with</em> for the past year or so. I think taking care of these issues will make my life a lot easier in the long run.</p> ]]></content:encoded> <wfw:commentRss>http://rexflex.net/2008/08/aesrijndael-encryption/feed/</wfw:commentRss> <slash:comments>6</slash:comments> </item> </channel> </rss>
