Hi community, are the plans to implement some "real" encryption functions - symmetric or even assymmetric - into AppGameKit Tier 1? I do not talk about hashing, I know that there are SHA functions existing.
Or did someone already implement some encryption function? Besides XOR I mean.
I am using the AppGameKit multiplayer networking functionality and want to transmit encrypted data from client to server for example used for user authentication.

Have a nice day!

Well you can send data over an SSL connection, that would be encrypted.

Well, as I wrote, I am using the AppGameKit Multiplayer Networking functions. There is no SSL there. I sure know that AppGameKit supports SSL for connecting to web resources.

The simplest encryption is simply just add an amount to the asci value of a character at a time
ie your key might be 13
cipher = (value + key) Mod(26) .......... to restrict it to the first 26 printable characters for example
to convert back
ciphertextLetter = (cipher + 65).......65 the starting character

you can also use a library of characters ie an array of the possible characters you want to be able to store
This also adds a double encryption method

I have the code to do the previous somewhere and when il find it il post it

Good old ROT13... I remember doing that in one of my first C++ lessons at college MANY years ago.

It sure was great using C++ and for gaming much better than object c I believe
and with an added array list of printable characters theres no reason why they cant be randomly arranged in the array
with some slight modifications to the formula. But not sure if they call that ROT13 when you do that.

Thought I had the appropriate functions for GDK which wouldn't be hard to convert AppGameKit but ive had a bit of a look with no luck
I will probably go to c versions of AppGameKit when i find a tutorial that covers more of a detailed setup. At the moment i get the
original template code to work but only way i can get other code to work is to modify the source template.
NO need to post here explanations or howto's

A while back, I posted this thread: https://forum.thegamecreators.com/thread/219421

Essentially it takes a random string and use as a key to encrypt and decrypt. Pretty basic stuff.

For user authentication, you should look into using Firebase as an auth server and use tokens from there to gain access to your backend API.
