裴秀智参加过哪些综艺:知道Secure File Transfer Protocol(安全文件传输协议)的进来

Secure File Transfer Protocol (also known as SFTP) is a type of File Transfer Protocol (FTP) software that allows you to upload your Web pages and other documents to a Web server. Most, if not all, Web developers are familiar with the term "FTP."

When you use an FTP program to access a Web server, you are sending data between your local machine and the server "out there" somewhere. This information can be intercepted by unscrupulous Web hackers or even the kid next door. This means that anything you send across the Web, to include your username and password, can be viewed by anyone with the right tools.

In recent years, Web server administrators have become increasingly concerned for the safety of their clients' information (you) and the Web server where Web pages reside. If you use the same password and username for your email, your Web site, your online banking account, etc., you run the risk of someone finding out what your username and password are. Usually, email and online banking transactions are "secure," which means that no one can intercept your username and password as you work across the Web. This is not necessarily true for connecting to a Web server when you upload or download files.
