Comment:

 There's an implementation in my `bug24660`
 [https://gitweb.torproject.org/user/isis/tor.git/log/?h=bug24660 branch]
 ([https://travis-ci.org/isislovecruft/tor/builds/365348704 Travis mostly
 passes], just not the cargo offline mode). The added dependency for
 rand_core is in the `master` branch of my tor-rust-dependencies
 [https://github.com/isislovecruft/tor-rust-dependencies repo], but from
 https://github.com/rust-lang-
 nursery/rand/issues/386#issuecomment-380489759 it looks like we should
 wait a few days to vendor rand_core-0.1.0.
