Random number generators

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.

It just came up here. It looks like PCG compares favorably with 
ChaCha20, but
this is PCG's page and the comparison is not very clear ("Secure" vs 

It may be worth considering though.
