Hashing strings

Unity Engine

Hi.
How I can hashing some strings like “dog” to “sdgtdf” and back ?

Unity does not provide anything for this matter and unless I’m wrong, Mono 1.2.5 does not have anything out of the box too, so you would have to add in a solution that offers it or implement one yourself

That how I can secure PlayerPrefs in registry ? Player can edit this so it’s not good.

Base64 is quite easy to do. Look into System.Convert.FromBase64String and friends.
