SFTP is the abbreviation for Secure File Transfer protocol, security File Transfer Protocol. You can provide a secure encryption method for transferring files. SFTP is a part of SSH and is a secure way to transfer files to the server. SFTP is the use of encrypted transmission of authentication information and transmitted data, so the use of SFTP is very safe. However, because this transmission uses the encryption/decryption technology, the transfer efficiency is much lower than the normal FTP, and if you have higher network security requirements, you can use SFTP instead of FTP.

The Channelsftp class is the Jsch implementation of the SFTP core class, which contains all of the sftp methods, such as: Put (): File Upload get (): File download CD (): Enter the specified directory ls (): Get a list of files in the specified directory Renam E (): Rename the specified file or directory rm (): Delete the specified file mkdir (): Create Directory RmDir (): Delete directory and so on (here omit the method parameters, put and get have multiple overloaded methods, see the source code, not listed here. ）

A simple Jsch link to Linux and execute the utils of the command.
