nit: No need for both "from scratch" and "(random)"

[rmsousa, 2013/03/06 04:36:49]

Done.

[Wez, 2013/03/06 00:43:25]

Looking at the call-sites, can this be static scoped_refptr<> FromString(), and
similarly for Generate(), above?

[rmsousa, 2013/03/06 04:36:49]

Done.

[rmsousa, 2013/03/06 04:36:49]

The SSL APIs don't take const parameters. I'm not sure if they actually touch
the key, or if it's just because it's pure-C underneath, but in any case, I
prefer to leave it as non-const than to cast it away on the call site (casting
const away is fairly evil, in general)
