Hey everyone,
If I XOR probably random data with good enough random data, does that
result in at least good enough random data?
I'm working on some Javascript client side crypto. There's a cryptographic
quality random generator present in modern browsers, but not in older ones.
I also don't

If you are truly concerned, have you considered implementing a proper
CSPRNG yourself in Javascript

I don't see how it could reduce the randomness to XOR with patterned data.
If someone knows better of this, let me know. If I'm correct that also
means it should be okay to reuse the few KB's should they ever run out (in
this system), at worst it no longer
You're talking about two different things here.
As others have said, if you XOR good random with 'not very good but
non-malicious random' - you are unlikely to reduce the entropy. (And
as Seth said, if you XOR good random with malicious random (e.g. a
trojaned RDRAND instruction) you're in bad

Yes, but other mixing functions are better.
Best to hash all streams together, rather than xor them together.

my money on:
WideBand Quadrature Receiver System
(no doubt they build very nice ones...)
