iOS Web Push Decryption Code

This code is the client-side decryption code from the Toot! iOS client, which uses the toot-relay web push proxy. It sets up keys and decrypts incoming notifications relayed over APNS from the web push proxy.

The code should compile stand-alone, but may contain some Mastodon-specific parts still. Use it as the basis of your own implementation!

This code includes a slightly edited copy of Luke Park's SwiftGCM code to handle aes-gcm decryption.
