How Do Random Number Generators Work? - TechSpective

WebAn ordinary random number generator only needs to produce statistically well-distributed numbers, but that doesn't mean they have to be hard-to-predict. In cryptography, we need hard-to-predict numbers in order to generate hard-to-guess keys. WebIdeally, the output of any encryption algorithm, will appear very nearly to be random. This also requires that the key utilized in that algorithm also be nearly random. This brings us to pseudo random number generators. They are called ‘pseudo’ because the output is not truly completely random. portsmouth 1986
