openssh unix dev - Jul 2017 - Openssh 6.5p1 - diffie hellman key agreement scheme

Hi All,

Can any one help to find out which of the following scheme(s) are
supported by openssh 6.5p1:

dhHybrid1, MQV2, dhEphem, dhHybridOneFlow, MQV1, dhOneFlow, dhStatic.

I see from the code, the 'p' and 'g' are static. Other
parameters are
ephemeral. Hence could not conclude if that is dhStatic or dhEphem.

Thanks in advance.

Regards,
Murugesh P.

I don't know what these names are referring to. OpenSSH supports
Diffie-Hellman in both specified well-known groups and in groups
that are selected at runtime. In all cases, the keys are ephemeral
and are never reused between connections.
