In 1984, Laind Huntsman, the head of software development for Formaster, a software protection company, commented that "no protection system has remained uncracked by enterprising programmers for more than a few months". Therefore, software producers generally tried to implement some form of copy protection before releasing it to the market. Softwares are inherently expensive to produce but cheap to duplicate and distribute. Educational resources for reverse engineering and software cracking are, however, legal and available in the form of Crackme programs. It might be legal to use cracked software in certain circumstances. There have been lawsuits over cracking software. The distribution of cracked copies is illegal in most countries. Software cracking is closely related to reverse engineering because the process of attacking a copy protection technology, is similar to the process of reverse engineering. A nukewar has shown that the protection may not kick in at any point for it to be a valid crack. nfo files that these type of cracks are not allowed for warez scene game releases. A well-known example of a loader is a trainer used to cheat in games. A loader modifies the startup flow of a program and does not remove the protection but circumvents it. This has the advantage for a cracker to not include a large executable in a release when only a few bytes are changed. A patch is a small computer program that modifies the machine code of another program. A keygen is a handmade product serial number generator that often offers the ability to generate working serial numbers in your own name. Some of these tools are called keygen, patch, loader, or no-disc crack. Ī crack refers to the means of achieving, for example a stolen serial number or a tool that performs that act of cracking. Examples of software cracking includes: bypassing software registration and payments, converting a trial/demo version of the software into fully-functioning software without paying for it, removing the need for hardware security module, breaking CD or DVD copy protection or removing annoying features of a software such as nagware or adware. Software cracking contributes to the rise of online piracy where pirated software is distributed to end-users.
Software cracking (known as "breaking" mostly in the 1980s ) is an act of removing copy protection from a software.
