"Python基础应用：Paramiko库实现SSH协议原理与远程文件传输"

Paramiko.pptx is a Python library that implements the SSHv2 protocol and provides functionality for remote command execution, file transfer, and other SSH-related operations. The library includes features for password and public key authentication, as well as for establishing secure channels for remote copy (scp) and secure file transfer (sftp). Paramiko is a third-party library that must be installed separately. The core component of Paramiko is the SSHClient class, which encapsulates SSH sessions and provides methods for establishing channels and SFTP connections. The SSHClient class is similar to the ssh command in Linux and can be used to execute remote commands. It also provides functionality for opening secure file transfer protocol (SFTP) connections. The SFTPClient class, on the other hand, is similar to the sftp command in Linux and is used for performing remote file operations such as uploading, downloading, and modifying file permissions. Paramiko relies on the underlying cryptography library to implement the SSHv2 protocol, and it uses the Channel class to establish communication channels similar to sockets. Overall, Paramiko provides a comprehensive set of tools for working with SSH and SFTP in Python, making it a valuable resource for developers seeking to perform secure remote operations.
