The whole purpose of urandom is to have a non-blocking source of random numbers: http://man7.org/linux/man-pages/man4/random.4.html and os.urandom() has always stated: "This function returns random bytes from an OS-specific randomness source. The returned data should be unpredictable enough for cryptographic applications, though its exact quality depends on the OS implementation." That's pretty much in line with what the implementation now does. There's no promise on the quality of the data it returns. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26839> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
