At Google scale you can roll your own crypto. Or routers. Or hardware. Or CPU.

Maybe not smart to roll your own everything, but a few of them sure.

I doubt they'd roll their own, but I bet Google has the talent to make very good implementations of proven crypto.

That's the sort of thing I'm talking about. Good implementations of known-good crypto.

I don't doubt that Google's trying to come up with new, novel cryptographic methods as well, but those take a long time to develop, test, and get reviewed. RSA didn't show up over-night and SHA3 has taken some time to get ready for production.

Google has the talent to roll its own crypto, and in fact it often does.
