Written in C# using part of the .Net framework, SecuSave is a game save solution to prevent save hacking. It is as easy to use as PlayerPrefs, with the added protection of AES encryption. Instead of using PlayerPrefs in some convoluted way, it saves its own files to the Application.persistentDataPath.

SecuSave offers the ability to save a large number of data types, including the primitives, arrays, and even some Unity specific types. All data can be deleted and new save files initialized with just a single line of code. Individual entries can also be deleted if desired.

It does depend on several libraries in the System namespace, including Security.Cryptography and Runtime.Serialization, but this has been tested to work on Android and iOS as well. It can even be called from a Javascript file.
