SharpMusique was a rewrite in C# of PyMusique (written in Python), both programs were iTunes Music Store clients, allowing songs to be downloaded from the iTunes Music Store without DRM.

C Sharp (programming language) Multi-paradigm (object-oriented) programming language

C# is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed around 2000 by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO. C# is one of the programming languages designed for the Common Language Infrastructure.

Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides constructs that enable clear programming on both small and large scales. Van Rossum led the language community until stepping down as leader in July 2018.

Digital rights management (DRM) is a set of access control technologies for restricting the use of proprietary hardware and copyrighted works. DRM technologies try to control the use, modification, and distribution of copyrighted works, as well as systems within devices that enforce these policies.

PyMusique

PyMusique was written by Travis Watkins, Cody Brocious, and Jon Lech Johansen for the purpose of allowing downloading songs from the iTunes Music Store before DRM was applied to them from a Mac, Linux, or Windows computer. It was first released via Johansen's website on March 18, 2005. Although the iTunes Music Store's method of applying FairPlay DRM to the songs was widely known, PyMusique was the first program to exploit a loophole in the system, allowing users to download songs without the DRM restriction. On March 22, 2005, Apple released an update that rendered PyMusique non-functional. The same day, a new version of PyMusique was released that worked again, only without Windows compatibility. On March 31, 2005, Johansen released SharpMusique, the Windows-compatible port of PyMusique. [1]

Cody "Daeken" Brocious is an American software engineer best known for his work on PyMusique and his demonstration of a hotel lock vulnerability in 2012 that affected several million locks in the US and was widely reported in the media.

Jon Lech Johansen, also known as DVD Jon, is a Norwegian programmer who has worked on reverse engineering data formats.

Linux Family of free and open-source software operating systems based on the Linux kernel

Linux is a family of free and open-source software operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution.

PyMusique also allowed songs to be re-downloaded for free, in case a user accidentally deleted their purchase. Within a number of days, Apple broke the client by forcing all users to upgrade to iTunes 4.9. [2] In response to Apple's actions, Johansen released PyMusique version 0.4 on March 22, 2005 , which allows users once again to use PyMusique with Apple's store.

iTunes media player and library software

iTunes is a media player, media library, Internet radio broadcaster, and mobile device management application developed by Apple Inc. It was announced on January 9, 2001. It is used to play, download, and organize digital multimedia files, including music and video, on personal computers running the macOS and Windows operating systems. Content must be purchased through the iTunes Store, whereas iTunes is the software letting users manage their purchases.

With the launch of 0.4, developer Cody Brocious stated on his blog that no future versions of PyMusique would be released with Microsoft Windows support.

Microsoft Windows is a group of several graphical operating system families, all of which are developed, marketed, and sold by Microsoft. Each family caters to a certain sector of the computing industry. Active Windows families include Windows NT and Windows Embedded; these may encompass subfamilies, e.g. Windows Embedded Compact or Windows Server. Defunct Windows families include Windows 9x, Windows Mobile and Windows Phone.

SharpMusique

In September 2005, Jon Lech Johansen released SharpMusique, written in C#, which took over where PyMusique left off. The program was kept updated until version 1.0, at which point it was no longer updated. The iTunes protocol changed, and users of SharpMusique were able to release primitive patches to account for the changes until mid-2006, when the protocol changed drastically. Around this time, without public announcement, the download links for SharpMusique and its source were removed from Johansen's website. [3] As a result, it is no longer easily available.

FairPlay is a digital rights management (DRM) technology developed by Apple Inc. It is built into the MP4 multimedia file format as an encrypted AAC audio layer, and is used by the company to protect copyrighted works sold through iTunes Store, allowing only authorized devices to play the content.

QTFairUse

QTFairUse is a software application first released in November 2003 by Jon Lech Johansen. It dumps the raw output of a QuickTime AAC stream to a file, which could bypass the digital rights management (DRM) algorithm called FairPlay used to encrypt music content of media files such as those distributed by the iTunes Store, Apple's online music store. Although these resulting raw AAC files were unplayable by most media players at the time of release, they represented the first attempt at circumventing Apple's encryption. These early versions of QTFairUse would save only the "raw" AAC, but later incarnations properly supported full conversions.

Apple Lossless, also known as Apple Lossless Audio Codec (ALAC), or Apple Lossless Encoder (ALE), is an audio coding format, and its reference audio codec implementation, developed by Apple Inc. for lossless data compression of digital music.

Traditionally, Apple has referred to the codec as Apple Lossless, though more recently it has begun to use the abbreviated term ALAC when referring to the codec.
