Riak CS doesn't like SHA-256?

[iby]

While trying to setup the an instance I came across the problem where it didn't like a certificate with SHA-256 digest. I googled and found that earlier Erlang versions didn't support it with some references to Riak.

I followed this guide on how to generate signed certificates, which is considerably better than the one in the documentation and also includes steps on how to generate the CA. Probably would help others too if you use that instead of what you have there now.
