difference in key exchange

In Session Options -> SSH -> Key exchange
what is the difference between diffie-hellman and diffie-hellman-group?

I'm trying to connect to switches and they say they only take diffie-hellman.
Is diffie-hellman the same as df group1? or is diffie-hellman-group df group1?

I'm pretty confused!

Hi geodude,

Thanks for the post. You may want to read the RFCs to really find out about the differences between the various versions of diffie-hellman.

Here is a line from the trace options output of a connection:
[LOCAL] : Available Remote Kex Methods = diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
Here is the correlation of the three older versions of Diffie-Hellman from the trace options output to the options in SecureCRT:
Diffie-Hellman = diffie-hellman-group1-sha1
Diffie-Hellman-Group14 = diffie-hellman-group14-sha1
Diffie-Hellman-Group = diffie-hellman-group-exchange-sha1
Does this help to answer your question?
