I think it's better than what we have in
So is having a high-quality, lockless (per-thread) CSPRNG good enough for now?
Phrased like that, I think so. We have enough other stuff to do. So +1 to
Kurt's per-thread approach.

It is good that Tim hit the break and requested a discussion. That was
overdue and it is unfortunate that we did not start it much earlier. I
think Tim brought up to important points:
1. We need to to pause for a discussion to determine the direction to
go. Otherwise the DRBG implementation will

So a major reason, as you explained, for having per-thread DRBG's is to reduce
contention. When threadA creates an SSL object, the parent DRBG will be the

We have to keep in mind what threats we care about and their practicality.
The security of a DRBG is dependent on both the secrecy of the seed
material provided and the security of the algorithm in terms of its output
not leaking information that materially leaks the internal state in a
manner

So Tim has voted -1 on PR #5547 and wants us to discuss it here
and vote on it.
I don't know if it's clear to everybody what this is about. If
something is not clear, please ask. PR #5461 contains a
