An "illegal prime" is an illegal number that happens to be a prime number; it appears that the idea is interesting to some people because you can put it on a website or something and say "hey, check out this prime number", and then the legal case against you might be weaker than if you were just publishing a random illegal number. (This is all rather theoretical, because the specific information being encoded in the examples cited, the code for the DeCSS program, has already been published in its full form by many people, in most cases with no legal repercussions.) Anyway, this concept, whether interesting or not, seems to lack notability. Of all the references here, most are to self-published websites (which probably shouldn't be getting cited at all), one is to a Wall Street Journal article that doesn't specifically mention illegal primes, and finally there's a short article in The Register which, if I'm counting correctly, spends 2 of its 6 sentences talking specifically about illegal primes. There simply does not appear to be any significant coverage of this concept. Korny O'Near (talk) 00:42, 7 December 2015 (UTC)
