 Security wise, every incoming message will get processed as follows:
 
-Every message that gets sent to the server get's a signature appended. Signing happens with an RSA key that is generated for you if it doesn't exist already, and then stored in the kde wallet, so your private key for signing doesn't change from that moment on. When starting a connection, the full credentials of the client are sent along, later messages just contain a hash of the key to identify the sender without having to put all the information in every message.
+Every message that gets sent to the server gets a signature appended. Signing happens with an RSA key that is generated for you if it doesn't exist already, and then stored in the kde wallet, so your private key for signing doesn't change from that moment on. When starting a connection, the full credentials of the client are sent along, later messages just contain a hash of the key to identify the sender without having to put all the information in every message.
 Whenever a message is received and the Credential's trustLevel is at least ValidCredentials (meaning, the signature of the message is at least valid for the public key), the combination service name and public key signature is used to see if there are any AuthorizationRules that already match this request. These are both rules defined in /etc/plasma-remotewidgets.conf and rules that are created for the current plasma session only. If a matching rule is found, it is applied (that is, the message is either accepted or denied). Else a new rule is created, that is at that moment still Undefined. This rule, containing an instance of Credential that can be used to obtain a trustLevel, will be passed to the active AuthorizationInterface's authorizationRequest. The interface can then decide to either accept or deny the request, or request PIN pairing, in which case the user will have to enter the same password on both client and server to establish a connection.
 NOT YET IMPLEMENTED: additionally, a message can also be signed with a GPG key, in which case the trustLevel can go beyond ValidCredentials. Either by having that key in your trusted keyring, or, for UltimateCredentials, having it signed by the plasma overlords themselves.
