Introducing UniCipher : encrypt your playerprefs and any string to make them unreadable

You want to make your text uneasily readable, try to encrypt it using this method: UniCipher.

I’ve made this simple C# script to convert your text into an unreadable text so no one can easily understand and modify it.

Make a script named UniCipher.cs and paste this:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class UniCipher : MonoBehaviour
{

    public static UniCipher instance;
    public string separator = "@"; //never use @ as a letter right hand pair because it is used as separator.

    List<string> definitions;

    void Start()
    {
        DontDestroyOnLoad(this.gameObject);
        instance = this;

        definitions = new List<string>();

        definitions.Add("a-jkhd");
        definitions.Add("A-htr4");
        definitions.Add("b-4fdd");
        definitions.Add("B-4hfd");

    }

    public string Encrypt(string text) {
        string result = "";
        foreach (char c in text) {
            result += CharEncrypt(c);
        }
        return result;
    }

    public string Decrypt(string text) {
        string[] enctext = text.Split(char.Parse(separator));
        string result = "";
        foreach (string part in enctext) {
            Debug.Log(CharDecrypt(part));
            result += CharDecrypt(part);
        }
        return result;
    }

    public string CharEncrypt(char c) {
        foreach (string definition in definitions) {
            if (char.Parse(definition.Split('-')[0]) == c) {
                return definition.Split('-')[1] + separator;
            }
        }
        return c.ToString() + separator;
    }

    public string CharDecrypt(string part) {
        foreach (string definition in definitions)
        {
            if (definition.Split('-')[1] == part)
            {
                return definition.Split('-')[0];
            }
        }
        return part;
    }

}

Attach it to a game object, and play around with Encyrpt and Decrypt methods of this script.
