Instead of implement SSDP protocol or any else, use a very simple mechanism: send to the clients information as a JSON format.\n\nPyDiscover is very flexible and lightweight, and incorporates a cypher mechanism to secure (password based) the communication between server and clients.\n\nFeatures\n--------\n\n- Simple usage.\n- Configurable multicast service discovery.\n- Password protected access to server info (optional).\n- AES encryption (if you defines a password).\n- Custom channel definition.\n- High server performance, based in the new Python asyncio module.\n- Server can spread any information to clients. This information are sent/received as a JSON format.\n- Simple configuration file\n\nInstall\n-------\n\nInstall is so easy:\n\n.. code-block:: bash\n\n    # python3.4 -m pip install pydiscover\n\nHow it works?\n-------------\n\n**Architecture**:\n\nPyDiscover is composed by client and server:\n\n- Server listen for multicast clients request in the port 50000 (by default).\n- Clients send requests using a multicast address to the port 50000.\n\n**Virtual Channels (or magic)**:\n\nClient and server must transmit information in the same *virtual channel (or magic)*. The magic is a pre-shared word that server/client known. Only messages with this word will be attended, performing the \"virtual channel\".\n\n**Hidden mode**:\n\nBy default (per security reasons) server runs as **hidden mode**. This is: if server receives a messages without the correct magic or with wrong password, doesn't answer nothing to the client request. If we want that server answer with error message, we'll activate explicitly.\n\n**Securing communication**\n\nWe can set a password for the server. When it's set, the information will be sent cyphered using AES to the clients. Only in the clients known the password could be understand the messages.\n\n**Sent/received information**\n\nServer must be started with *-d* param. This param referees to a *.cfg* file. This file must have the format:\n\n.. code-block:: ini\n\n    [DEFAULT]\n    services = 10.0.0.1\n    net_password = asfi0j9ask123\n\n- A *[DEFAULT]* section.\n- Any information as: *key = value*.\n\nThe DEFAULT section content will be sent as a JSON format to the clients.\n\nUsage\n-----\n\n**Server**\n\nStarting server in port 40000, with a password an the virtual channel is build by word: \"askskAls828\":\n\n.. code-block:: bash\n\n    # pydiscover-server -p 40000 --password 1238d8KKls_jj -m askskAls828 -d example.cfg\n\nDisablind hidden mode:\n\n.. code-block:: bash\n\n    # pydiscover-server -p 40000 --password 1238d8KKls_jj -m askskAls828 -d example.cfg --disable-hidden\n\nYou can see more examples typing:\n\n.. code-block:: bash\n\n    # pydiscover-server -h\n\n**Client**\n\nConnecting to the server with the above configuration:\n\n.. code-block:: bash\n\n    # pydiscover-client -p 40000 --password 1238d8KKls_jj -m askskAls828 -v\n\nReal example\n------------\n\n.. image:: https://raw.githubusercontent.com/cr0hn/pydiscover/master/pydiscover/example.jpg\n\nWhat's new?\n-----------\n\nVersion 1.0.0\n+++++++++++++\n\n- First version released\n\nLicense\n-------\n\nPyDiscover is released under BSD licence.",
