You're right, this seems unreasonable for 32 bytes of random data,
especially in this context. Alexandre has the final word anyway, so
submitting to wine-patches was a good idea. Again, sorry I didn't see all
this up front, but I'd like to suggest the following improvement:
If OpenSSL is available, go ahead and use RAND_bytes, but call RAND_add
first with the input buffer. I don't have a good estimate for the number
of bits of entropy to expect, since we don't know whether the caller will
actually have provided a seed. Assuming it's unlikely, maybe
RAND_add(pbBuffer, dwLen, dwLen / 16.0f)?
And go ahead and fall back to /dev/urandom if OpenSSL isn't available.
