Hi All, I need suggestion from all the experts for a concern of mine. I am working on a windows forms app and we need to encrypt certain data and store it on a local file. The key used for encrypting or decrypting certain confidential data (which is finally written to a file) is there in the source code itself. When we deploy our applications the source code can be easily opened up using ildasm or Reflector. It means somebody can comfortably extract out the key used for encrypting the strings. How can I prevent this? I had heard of something called native code deployment using ngen.exe which I have no idea about or its pros and cons. Can someone please suggest as to how should I go about implementing this so that after deploying the application nobody can extract the source code? Thanks in advance Cheers, Girish Jain _________________________________________________________________ Get the new Windows Live Messenger! http://get.live.com/messenger/overview =================================== This list is hosted by DevelopMentor® http://www.develop.com
