A simple library to generate random data, using the system's PRNG.

The following sources of randomness are used depending on platform:

  • On OpenBSD, arc4random(3)<http://man.openbsd.org/arc4random.3>_ is used.
  • On Windows, RtlGenRandom()<https://msdn.microsoft.com/en-us/library/windows/desktop/aa387694%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396>_ is used.
  • On recent (>=3.17) versions of the Linux kernel, getrandom(2)<http://man7.org/linux/man-pages/man2/getrandom.2.html>_ is used.
  • On all other posix systems, /dev/urandmon is used.

TODO

  • Implement generation of random data on OpenBSD using arc4random(3)
  • Implement generation of random data on Linux >= 3.17 (using getrandom(2))
  • Implement generation of random data on Windows
  • Implement generation of random data on Linux < 3.17 (kernels without getrandom(2))
  • Implement generation of random data on other posix systems
