Paramiko authentication with certificate and oprivate key

Question

I have a linux device which supports authentication with a certificate and a private key.

I have tried to connect with:

k = paramiko.RSAKey.from_private_key_fil("path to privte key")
client.connect(server,port,user, key_filename ="path to certificate file", pkey=k)

I cannot connect in any way to the device.

Under windows with OPEN SSH I can connect to the device with :

ssh [email protected] -p 22 -o IdentityFile=C:\client_key\client_key -o CertificateFile=C:\client_key\OTCsigned_certificate

Answer 1

I have solved the issue by : Renaming the key and the certificate as id_rsa and id_rsa-cert.pub.

At argument key_filename i passed the certificate and alongside with it the paramiko loads also the private key.

It is finally working.
