Newbie question. I am trying to set up game circle and hopefully game-save sync.
While setting up
Add or Edit GameCircle Configuration
I am stuck at step 2
Select a platform to generate the API key
as it requires MD5 Signature and SHA256 Signature. I know how to get MD5 Signature from this blog https://coronalabs.com/blog/2014/08/26/tutorial-understanding-android-app-signing/
but I can't find anywhere how to get the SHA256 Signature.
Question 1: How to generate a SHA256 Signature?
Question 2: If I like to save a json.encode save game(with lots of strings, numbers, texts), I should gamecircle.Whispersync.DeveloperString use is that correct?
Thank you in advance. I am really not good with all these signing and networking thing.
