This article mainly talks about "what's the difference between SFTP and FTP". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what's the difference between SFTP and FTP?"

1. Applicable scenarios

We are used to using ftp to upload and download files, especially in many Linux environments, we usually connect to Linux through third-party SSH tools, but when we need to transfer files to Linux servers, many people are used to using ftp to transfer files. In fact, Linux does not provide ftp by default, so you need to install an additional FTP server. And the ftp server side will occupy some VPS server resources. In fact, the author suggests using sftp instead of ftp.

Mainly because: first, you do not need to install any additional server-side programs (I prefer this, , many companies do not have an external network environment for security Linux, only SSH, want to transfer files is a very sad problem). Second, it will save system resources. Third, SFTP uses encryption to transmit authentication information and data, which is relatively more secure. Fourth, there is no need for separate configuration, which is relatively simple for beginners (enabling SSH enables SFTP by default).

II. Main differences

FTP is a file transfer protocol, generally designed to facilitate data sharing. Includes a FTP server and multiple FTP clients. FTP clients download resources on the server through the FTP protocol. The SFTP protocol encrypts the data on the basis of FTP, which makes the transmitted data more secure. But this kind of security comes at the expense of efficiency, that is, the transmission efficiency of SFTP is lower than that of FTP (although there is not much difference in practical use). Personal superficial view is: first, FTP should be installed, SFTP should not be installed. Second, SFTP is safer, but its side effect is that it is less efficient than FTP.

At this point, I believe you have a deeper understanding of "what's the difference between SFTP and FTP". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
