+"""Implementation of the TP-Link Klap Home Protocol.
+
+Encryption/Decryption methods based on the works of
+Simon Wilkinson and Chris Weeldon
+
+Klap devices that have never been connected to the kasa
+cloud should work with blank credentials.
+Devices that have been connected to the kasa cloud will
+switch intermittently between the users cloud credentials
+and default kasa credentials that are hardcoded.
+This appears to be an issue with the devices.
+
+The protocol works by doing a two stage handshake to obtain
+and encryption key and session id cookie.
+
+Authentication uses an auth_hash which is
+md5(md5(username),md5(password))
+
+handshake1: client sends a random 16 byte local_seed to the
+device and receives a random 16 bytes remote_seed, followed
+by sha256(local_seed + auth_hash).  It also returns a
+TP_SESSIONID in the cookie header.  This implementation
+then checks this value against the possible auth_hashes
+described above (user cloud, kasa hardcoded, blank).  If it
+finds a match it moves onto handshake2
+
+handshake2: client sends sha25(remote_seed + auth_hash) to
+the device along with the TP_SESSIONID.  Device responds with
+200 if succesful.  It generally will be because this
+implemenation checks the auth_hash it recevied during handshake1
+
+encryption: local_seed, remote_seed and auth_hash are now used
+for encryption.  The last 4 bytes of the initialisation vector
+are used as a sequence number that increments every time the
+client calls encrypt and this sequence number is sent as a
+url parameter to the device along with the encrypted payload
