iTunes Connect - Does my app contain encryption?

Im just submitting my app now and it asks me

Export laws require that products containing encryption be properly authorized for export. Failure to comply could result in severe penalties. For further information, click here.

I think i might be using it because im using the unity wiki highscores witch contains the md5.js script.
I think the md5 using encryption anyway. What should i do?

MD5 is not encryption, it is a message digest algorithm. There are many many unity games published and available around the world, so this export restriction should not apply. If your game does use encryption you may want to consult an attorney to discuss whether you need a license.
