Marc-Andre Lemburg added the comment: Resources for entropy gathering sources:
* Kernel based devices such as /dev/random: https://en.wikipedia.org/wiki//dev/random * EGD - old entropy gathering daemon; blocks when out of entropy http://egd.sourceforge.net/ (not maintained anymore) Important here is not the original implementation, but the Unix domain socket interface, which many applications support. * PRNG - provides the EGD interface, but feeds entropy into the OpenSSL pool; essentially a CPRNG with EGD interface. http://prngd.sourceforge.net/ * Virtio RNG - paravirtualized device for passing host RNG to guest VMs (running under KVM) https://fedoraproject.org/wiki/Features/Virtio_RNG * haveged - entropy daemon which feeds entropy into the Linux /dev/random pool http://www.issihosts.com/haveged/ https://wiki.archlinux.org/index.php/Haveged Whether this is useful on VMs, is contested, due to the way haveged works (reliance on rdtsc instructions which don't work well in VMs) http://security.stackexchange.com/questions/34523/is-it-appropriate-to-use-haveged-as-a-source-of-entropy-on-virtual-machines * Hardware RNG in Raspberry Pi: https://sites.google.com/site/astudyofentropy/project-definition/raspberry-pi-internal-hardware-random-number-generator * rng-tools - provides the rngd daemon to feed entropy from hardware RNGs into the Linux /dev/random pool https://wiki.archlinux.org/index.php/Rng-tools http://linux.die.net/man/8/rngd ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27279> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
