Question

I need to connect to a SFTP, download the most recent file, then change the file name and load again to the same SFTP folder and delete the \'original name\' file. I have do

Answer 1

It's important to specify that "password" is only used if server has a password. In case is your private key the one protected with password, you must use "private_key_pass" instead.

So to connect to a remote server with public/private key you need:

1) upload public key to server

2) create a connection with your private key + private key password:

srv = pysftp.Connection(host="host", username="username", private_key="file_with_private_key", private_key_pass="password")

Answer 2

To connect using a key file, you will want to pass the path to the key file when creating the connection. To do this, you'll set the parameter "private_key" to the path to the file.

Your code above should look something like this:

srv = pysftp.Connection(host="you_FTP_server", username="your_username", private_key="./Path/To/File")

When pySFTP initiates the connection, it will try to use the file you passed in. If it fails because of the keyfile, it will throw an authentication exception.
