+# obs-websocket 4.1 protocol reference
+
+**This is the reference for the latest 4.1 development build. [See here for obs-websocket 4.0.0!](https://github.com/Palakis/obs-websocket/blob/4.0.0/PROTOCOL.md)**
+
+# General Introduction
+Messages are exchanged between the client and the server as JSON objects.
+This protocol is based on the original OBS Remote protocol created by Bill Hamilton, with new commands specific to OBS Studio.
+
+
+# Authentication
+OBSWebSocket uses SHA256 to transmit credentials.
+
+A request for [`GetAuthRequired`](#getauthrequired) returns two elements:
+- A `challenge`: a random string that will be used to generate the auth response.
+- A `salt`: applied to the password when generating the auth response.
+
+To generate the answer to the auth challenge, follow this procedure:
+- Concatenate the user declared password with the `salt` sent by the server (in this order: `password + server salt`).
+- Generate a binary SHA256 hash of the result and encode the resulting SHA256 binary hash to base64, known as a `base64 secret`.
+- Concatenate the base64 secret with the `challenge` sent by the server (in this order: `base64 secret + server challenge`).
+- Generate a binary SHA256 hash of the result and encode it to base64.
+- Voilà, this last base64 string is the `auth response`. You may now use it to authenticate to the server with the [`Authenticate`](#authenticate) request.
+
+Pseudo Code Example:
+```
+password = "supersecretpassword"
+challenge = "ztTBnnuqrqaKDzRM3xcVdbYm"
+salt = "PZVbYpvAnZut2SS6JNJytDm9"
+
+secret_string = password + salt
+secret_hash = binary_sha256(secret_string)
+secret = base64_encode(secret_hash)
+
+auth_response_string = secret + challenge
+auth_response_hash = binary_sha256(auth_response_string)
+auth_response = base64_encode(auth_response_hash)
+```

+# Requests
+Requests are sent by the client and require at least the following two fields:
+- `request-type` _String_: String name of the request type.
+- `message-id` _String_: Client defined identifier for the message, will be echoed in the response.
+
+Once a request is sent, the server will return a JSON response with at least the following fields:
+- `message-id` _String_: The client defined identifier specified in the request.
+- `status` _String_: Response status, will be one of the following: `ok`, `error`
+- `error` _String_: An error message accompanying an `error` status.
+
+Additional information may be required/returned depending on the request type. See below for more information.
