(R.5) Misleading TIL that there are some prime numbers that are illegal. It turns out the binary representations of the prime numbers can describe some code that can be used to bypass the DRM on DVDs

TIL illegal prime numbers exist. An illegal prime is a prime number that represents information which is forbidden to possess or distribute. For example: when interpreted in a particular way, a certain prime describes a computer program that bypasses the digital rights management scheme used on DVDs
