My issue is that I have a putty client on a windows machine, trying to ssh to a Linux server (CentOS). The putty version is very old and it is NOT possible to take a newer version.

I would like to allow to use diffie-hellman-group1-sha1, but the explanations I found here => and here => don't seem to be OK for my case. Because in my case the client is old, not the server. And this is putty on windows, not ssh from a Linux.

Do you have an idea how I could allow sha1 on my Linux server please ?

Thank you,
