SFTP based on key multi-process batch concurrent upload file implementation case (Python)

Recent research on Paramiko,paramiko can be very convenient to implement the SSH protocol-based remote connection, which can be based on

Password, you can also have no password RSA asymmetric key, can also be implemented SFTP upload download operation, security and efficiency, combined with many

Process or multithreading can be implemented parallel processing, write a simple sftp based on key multi-process batch concurrent upload

File implementation case, for future reference.

Based on RSA asymmetric passwords (public and private), you need to create a key on the server and distribute the public key to the client

Create RSA key pair:ssh-keygen-t RSA

Copy the private key to the client:Ssh-copy-id [email protected]

The code is as follows:
