AES/Rijndael Encryption

Looking for AES encryption using Adobe Flex?
I get a lot of hits from people searching about how to use AES encryption in an Adobe Flex application. 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 AES Encryption Code Base for Air and Flex 3 in the Flex 3 Cookbook!

I’ve been pretty busy with work lately, but it has been very interesting. The past couple of days I’ve been working with the AES/Rijndael to encrypt sensitive user data in the application I’m currently working on. It has been pretty interesting and has proven to be quite a learning experience.

The main reason it has been a challenge is that some of this data that we’re encrypting needs to be decrypted and searched through for reports. We have already decided on using SQL Server Reporting Services (which I haven’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 create CLR User-Defined functions to handle this.

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 just dealing with for the past year or so. I think taking care of these issues will make my life a lot easier in the long run.

    Yeah, gravatar is pretty cool. I started to look into it and the theme I’m using is supporting the old plugin, but wordpress supports it out-of-the-box now. It will come in time :P
