Sftp is the abbreviation of Secure File Transfer Protocol, a secure file transfer protocol. Can provide a safe encryption method for transferring files. Sftp and ftp have almost the same syntax and functions. SFTP is a part of SSH and is a secure way to transfer files to the Blogger server.
In fact, the SSH software package already contains a secure file transfer subsystem called SFTP (Secure File Transfer Protocol). SFTP itself does not have a separate daemon. It must use the sshd daemon (the port number is 22 by default) to complete the response. The connection operation, so in a sense, SFTP is not like a server program, but more like a client program. SFTP also uses encryption to transmit authentication information and transmitted data, so it is very safe to use SFTP. However, because this transmission method uses encryption/decryption technology, the transmission efficiency is much lower than ordinary FTP. If you have higher requirements for network security, you can use SFTP instead of FTP.
