Hi Roumen, I discovered that the need of appending the .pub part of id_rsa(client key+cert) on the server can be eliminated by adding the Certificate Blob to authorized_keys which could look something like this: x509v3-sign-rsa subject= /C=FR/ST=PARIS/L=DESEl/O=SSL/OU=VLSI/CN=10.244.82.83/emailAddress=client at company.com This is extracted from the client certificate using openssl as

Hello everyone.. I am fairly new to the patching format.. so I just decided to post a basic info about how to remove group1 and group14 diffie key exchange in OpenSSH.
