Hi guys,
When I SSH into my home test server I see the following error on Putty:
"The first key-exchange algorithm supported by the server is diffie-hellman-group1-sha1".
As SHA1 is no longer secure, I'd like to switch to something more secure.
However, when I run
# ssh key-exchange group ?
configure mode commands/options:
dh-group1-sha1 Diffie-Hellman group 2
dh-group14-sha1 Diffie-Hellman group 14
I see that both the options are for sha1 only.
How can I use different hashing mechanisms?
Thanks,
Dario

Hi
it seems you don't have license for other security protocols, check it

Hello, Dario.
I would like to suggest you to change default algorithm on server, like this:
ssh key-exchange group dh-group14-sha1
That might help
