[erlang-bugs] Fwd: Re: Incomplete Elliptic Curve Cipher Suites in R16B01 and R16B02

Thanks Andrew!

These are good points!  I was actually using an ECC key, but I did
another mistake.

As I was just trying out very quickly, I accidentally specified the
-tls1_2 option on the wrong position and didn't check the output.  As
`openssl -tls1_2 s_client -cipher` terminates with status code 0, the
script's output was "works" for all cipher suites, hence I wrongly
assumed that it would be working.

Thanks again!
