A backdoor is a vulnerability in a form of encryption that would allow anyone who found it to undermine the protections that the encryption offers. "Backdoor" is a pejorative term used by people who oppose government efforts to require tech companies to design their encryption so that they can break it. These critics argue that the only way to do this is for the companies to deliberately insert vulnerabilities—the "backdoors"—into their encryption. Backdoors can take many forms; one example is a random-number generator algorithm whose number-generation is not truly random, but rather, predictable to anyone who knows how it was designed. By predicting the number generation, it is possible to foil the encryption built on top of it.
