Comparison of SSL Labs TLS Scores with Different Go Versions

If you use Hiawatha you get A+ with out of the box settings.

Just plugging it because it constantly outperforms my expectations and PolarSSL (now mbed owned by Arm), has avoided many of the recent openssl issues making my life less worrisome, but the dev doesn't really advertise or push it and relies on word of mouth more than anything.

It's worth checking out.

Zero is the number of TLS experts I know that would unreservedly recommend PolarSSL over Go's crypto/tls. I know several who wouldn't even recommend it over OpenSSL, but it's worth remembering that not only does Go's TLS not use OpenSSL, but it's curated by one of the world's experts in TLS security.

Go has one of the best TLS stacks in the world, and I expect the distinction to become starker in the future; in a few years, barring something unexpected from something like BoringSSL, it may end up being unquestioned best TLS stack.

Thanks for the info tptacek, do you have any reading along these lines that goes into any detail on this? From what I have been reading go tls is nice but computationally more intensive. I really like to go for the best wherever I can, so I am genuinely interested if anyone else has any input on this.

Do you have any proof to support this claim?

> Go has one of the best TLS stacks in the world,

Go suffers a bit from weak random numbers though (crypto/rand Read() output), says dieharder at least: http://nopaste.narf.at/show/31060/

I'm not sure how severe that is...

Horseshit. Go's crypto reads from urandom, just like Nacl.

Which means they set long HSTS by default, which will bite you quite badly if you're not ready yet for an irreversible HTTPS rollout. But yeah, A+ looks awesome on comparison tables, doesn't it?

No, it does not set a HSTS header by default. And the out of the box rating is A, not A+. However, with a simple setting you enable the HSTS header, which gives you the A+ rating.

The dev has tried to push it, but it seemed that nobody cares.
