If you stream premium video to iPhones, iPads, Apple TV, or Safari, Apple will not let you protect that content with Widevine or PlayReady. You need FairPlay DRM. It is the only digital rights management system Apple devices accept for HLS playback, which makes it a hard requirement for any service that licenses Hollywood titles, sports, or paid courses to Apple users.<\/p>\n

FairPlay DRM is Apple’s content protection technology that encrypts video and controls who can decrypt and play it. This guide explains what FairPlay DRM is, how the FairPlay Streaming key exchange works, which devices and formats it supports, and what it takes to add it to your own app. By the end you will know exactly where FairPlay fits in a multi-DRM strategy and how to get started.<\/p>\n

What Is FairPlay DRM?<\/h2>\n

FairPlay DRM is a digital rights management<\/a> system built by Apple that encrypts media and restricts playback to authorized devices and users. Apple first shipped it in 2003<\/a> to protect songs and videos bought through the iTunes Store. The modern version, FairPlay Streaming (FPS)<\/strong>, protects streamed video delivered over HTTP Live Streaming and is documented in Apple’s FairPlay Streaming<\/a> developer program.<\/p>\n

In plain terms: FairPlay scrambles your video with an AES-128 key, and only a device that passes Apple’s secure key exchange can get that key back to decrypt and watch the content. The decryption happens inside a protected layer of the operating system, so the raw key and the decoded frames never sit exposed in app memory where they could be copied.<\/p>\n

FairPlay is one of the three major DRM systems studios require for premium content. The other two are Google Widevine and Microsoft PlayReady. Each one covers a different set of platforms, which is why most streaming services run all three together. Understanding DRM-protected content<\/a> starts with knowing which system maps to which device.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

FairPlay vs Widevine vs PlayReady<\/h2>\n

No single DRM covers every device, so the practical question is not “which DRM is best” but “which DRMs do I need together.” FairPlay owns the Apple side. Widevine DRM<\/a> handles Android and Chrome. PlayReady covers Windows, Edge, and Xbox. Run all three and you reach almost every screen with a single encrypted set of files.<\/p>\n\n\n\n\n\n\n\n\n\n

The encryption mode matters. FairPlay historically used CBC mode, while Widevine and PlayReady started with CTR mode. The Common Media Application Format<\/a> and the CBCS encryption scheme now let all three share one set of encrypted CMAF files, so you no longer have to encode and store separate packages per DRM. That single change cut storage and packaging costs for multi-DRM by a wide margin.<\/p>\n

How Does FairPlay DRM Work?<\/h2>\n

FairPlay Streaming works by separating the encrypted video from the key needed to decrypt it. The video can sit on any CDN in the open, because it is useless without the key. The key only travels through a tightly controlled exchange that proves the requesting device is a genuine, authorized Apple device.<\/p>\n

That exchange has three actors: the client app<\/strong> on the Apple device, your key server<\/strong> (also called a Key Security Module), and Apple’s secure hardware on the device. Here is the flow, step by step.<\/p>\n
