It was expected and unfortunately it has come to pass. Niantic has force updated their official Pokemon Go app to encrypt communication, rending 3rd party apps (of which there are many on Android and the web) unusable.
One of the developers of PoGo writes:
Like you already know the PoGo app doesn’t work.
The reason for that is that Niantic updated their server.
The update ruined the API, the requests are now cryptographically signed.
The latest update was forced so the app could read it.
Does this mean that it is over?
No, the makers of the API are looking in to this, it is not sure if they can fix it.
What do you say? Is it over in your opinion?
Sadly, yes. I dont think that the API creators will be able to decrypt it and if they will be able to get it to work, Niantic will probably add more encryptions. This is probably one of the I don’t know how many encryption they will add.
We have to wait till the API creators have more news, I will keep you updated.
Or, you can look by yourself.
Fortunately for Windows Phone users there is a massive community of hackers trying to decipher the new protections on other platforms, with much progress already been made.
It will however remain a cat and mouse game between Niantic and Developers making a stable client for Windows Phone an issue going forward.
The progress of the hacking effort can be followed here.
