What is Illegal prime?
{{Orphan|date=May 2009}} An '''illegal prime''' is a special [[prime number]]. Such prime numbers are called illegal, because there is a way to change them, so that they yield something [[illegal]]: a program to circumvent the [[Digital Millennium Copyright Act]]. One of the first people to find such a prime was [[Phil Carmody]]. In 2001, he found a prime that contains the [[gzip]] [[data compression|compressed]] [[source code]] for a program that can circumvent the [[Content Scrambling System]]. The Content Scrambling System is used as a way to prevent [[DVD]]s from being copied. Later, other primes were found that resulted in directly runnable programs. The [[United States]] and other countries made it illegal to publish or circulate computer programs that can circumvent copy protection. Since prime numbers are a concept from [[mathematics]], their knowledge cannot be made illegal easily. Any information that can be represented in binary form can be represented as a number.
