Re: Deterministic RNG

Note for future implementation: Another thing that will have to change, is that currently the passes are done only in memory It is comforting that one pass is probably enough. But with high degree of chaotic randomness. The "wipe securely" function under tools/extras will use several passes (if you...

I am not sure how well the guarantees transfer to integers.
A simple mathematical function should do it.

Anyway, my main suggestion is to randomize short ranges and switch/reseed to offset the disadvantage of deterministic numbers.

Re: Deterministic RNG

A xoroshiro256+ with randomized range is also good and supposedly fast. [Also, can be used in combination with other algos]

Re: Deterministic RNG

Purpose is to wipe data but more securely, without too much deterministic number. There are many prng out there, but according to your method if reseed after randomized range, should be enough for non-deterministic standards without too much coding overhead. Of course you could adopt a variation of ...

Deterministic RNG

Could you consider a re-seeding cycle after a constantly randomized range, e.g., after rand(750-1250)K of data, so that over larger ranges less deterministic randomness is introduced?
