String encryption in objective C (iPhone) and decryption in C#

Hi All,

Today when I was working on one of my iPhone projects, we decided to use encryption for secure communication with .net web services. But I am very new to objective c and cryptography, so I am little bit worried and posted my question in http://stackoverflow.com and searched the web. Then I found the following blog by David Veksler — http://dotmac.rationalmind.net/2009/02/aes-interoperability-between-net-and-iphone/ , who posted the sample code for iPhone and .net. It really helped me a lot and saved ONE DAY for me.

Download the code directly from here [Download Code]

Thanks David…

Happy Coding…

There is no sdk with specified name or path “unknown path”

Hi all,

I am new iphone development, i just downloaded a project from web and i got following error

There is no sdk with specified name or path “unknown path”.

Here is the solution:

1. Select the main project file in xcode (main sheet which is the name of your project under the groups and files column to the left of your project)
2. Then select the blue circled “I” next to build and go
3. Go to the build panel and under the archetectures section go to the base sdk category and select iphone simulator #.# hit cmd + s and close that then choose that as your build and go method and build and go.

Enjoy….
