I need to send data from flash to t开发者_开发百科he server, so I'm looking for a flash ActionScript 3.0 script that will encrypt a text and a C# .net script that decrypt the text.

Can anyone help me here ?

Check out the as3corelib crypto package: http://code.google.com/p/as3corelib/source/browse/trunk/src/com/adobe/crypto/?r=49

And .NET has it's own cryptography namespace too: http://msdn.microsoft.com/en-us/library/system.security.cryptography.aspx
