Hello everyone!
The Secure Save System is up on the asset store: http://u3d.as/content/autosave-syndrome/secure-save-system
This system is extremely secure and easy to work with.
It’s a class working much like PlayerPrefs but instead of saving to the registry, it saves to a seperate file. It functions by encrypting the data and saving it into a text file. It then loads the data and decrypts it so the data is ready to use. Able to save integers, floats, bools, strings as well as arrays, lists, vectors, colors and quaternions. It can also save transforms (position, rotation and scale).
The price is 15$.
