<p>For multiple reasons, it’s very difficult to clearly define the protocol names and versions of the components that make up the AirPlay streaming system.

In order to tidy up this whole mess a bit, I did a little research that I’d like to summarize here:</p>
|
||||
<p>The very origin of the AirPlay protocol suite was launched as AirTunes sometime around 2004. It allowed to stream audio from iTunes to an AirPort Express station. Internally, the name of the protocol that was used was RAOP, or Remote Audio Output Protocol. It seems already back then, the protocol involved AES encryption. A public key was needed for encrypting the audio sent to an AirPort Express, and the private key was needed for receiving the protocol (ie used in the AirPort Express to decrypt the stream). Already in 2004, the public key was reverse-engineered, so that <a href="http://nanocr.eu/2004/08/11/reversing-airtunes/">third-party sender applications</a> were developed.</p>
|
||||
<p>Some time <a href="https://weblog.rogueamoeba.com/2008/01/10/a-tour-of-airfoil-3/">around 2008</a>, the protocol was revised and named AirTunes 2. It seems the changes primarily concerned timing. By 2009, the new protocol was <a href="https://git.zx2c4.com/Airtunes2/about/">reverse-engineered and documented</a>.</p>
