Technique:

C++

C#

.NET Framework 4.0

Visual Studio 2012

Task:

I need a c++ dll which has an encryption and decryption method.

The method should be very complex.

I think about a combination of several encryption methods.

This dll has to be integrated in a c# software.

From this c# software a string (see below) will send to the encryption-method and the return value is a encrypted string.

From this c# software a encrypted string will send to the decryption-method and the return value is the decrypted (original) string.

Sample for the original string:

"<Name>Tom Miller</Name><City>London</City><Country>United

Kingdom</Country>"
