You need to look at the explanations on other PCG pages to see what the = criteria are. Also this narrative is helpful: = <http://www.pcg-random.org/other-rngs.html>. At the bottom of that page, PCG is also considered and it is not = recommended as of cryptographic quality because it has not been tested = and challenged enough. In non-cryptographic use it may also be important to understand that = reseeding or mixing that involves capturing "more entropy" may be = delayed because of exhaustion of a periodic source, and one has to wait = for more bits, making attempted cryptographic quality even slower.=20 -----Original Message----- From: owner-freebsd-numerics@freebsd.org = [mailto:owner-freebsd-numerics@freebsd.org] On Behalf Of Pedro Giffuni Sent: Tuesday, March 17, 2015 11:39 To: Mehmet Erol Sanliturk Cc: dennis.hamilton@acm.org; freebsd-numerics@freebsd.org Subject: Re: Random number generators [ ... ] It just came up here. It looks like PCG compares favorably with=20 ChaCha20, but this is PCG's page and the comparison is not very clear ("Secure" vs=20 "Challenging"?) It may be worth considering though.
