Ответ на мою проблему заключается в следующем:
как прочитать ключ rsa
pkey = paramiko.RSAKey.from_private_key_file('/Users/rajesh.maulekhi/Downloads/id_rsa')
функция resturn sftp client
def multifactor_auth_sftp_client(host, port, username, key, password):
#Create an SSH transport configured to the host
transport = paramiko.Transport((host, port))
#Negotiate an SSH2 session
transport.connect()
#Attempt authenticating using a private key
transport.auth_publickey(username, key)
#Create an event for password auth
password_auth_event = threading.Event()
#Create password auth handler from transport
password_auth_handler = paramiko.auth_handler.AuthHandler(transport)
#Set transport auth_handler to password handler
transport.auth_handler = password_auth_handler
#Aquire lock on transport
transport.lock.acquire()
#Register the password auth event with handler
password_auth_handler.auth_event = password_auth_event
#Set the auth handler method to 'password'
password_auth_handler.auth_method = 'password'
#Set auth handler username
password_auth_handler.username = username
#Set auth handler password
password_auth_handler.password = password
#Create an SSH user auth message
userauth_message = paramiko.message.Message()
userauth_message.add_string('ssh-userauth')
userauth_message.rewind()
#Make the password auth attempt
password_auth_handler._parse_service_accept(userauth_message)
#Release lock on transport
transport.lock.release()
#Wait for password auth response
password_auth_handler.wait_for_response(password_auth_event)
#Create an open SFTP client channel
return transport.open_sftp_client()
