Thank You.

Encode them, store the encoded string in a resource file, include the resource and use a reverse algorithm to decode your strings.

But i doubt that will stop a medium cracker anyway. They will debug your tool and track your decoding algorithm.

You could get a good obfuscator that supports string encryption.
