Python 2 and Python 3, the two versions of the programming language in widespread use, include a function called shuffle that can randomize a list or another sequence of data.

Cryptography, too, relies heavily on random numbers for the generation of unbreakable keys. Better, cheaper ways of generating and handling such numbers are therefore always welcome.

A new network paradigm can generate meaningfully random numbers—and fast. In network encryption, randomness has huge value because it’s not “solvable” by hackers. Classical computers can ...
