Can we rely on /dev/urandom on UNIX machines if we need a cryptographically secure random generator?

  • Yes, that's the purpouse of /dev/random and /dev/urandom – Mr. E Dec 26 '16 at 21:12

From This Site:

Both /dev/urandom and /dev/random are using the exact same CSPRNG (a cryptographically secure pseudorandom number generator). They only differ in very few ways that have nothing to do with “true” randomness.

    You beat me to it, that site is the default reference for confusion about /dev/urandom. – Arminius Dec 26 '16 at 21:19
  • I laughed when I read your comment. I often have people beating me to the punch, but rarely do it to others .. Maybe I'm slower than most ... – user34445 Dec 26 '16 at 21:20
