window中使用PSFTP/WinSCP實現SFTP上傳下載

摘自百度百科

sftp是Secure File Transfer Protocol的縮寫，安全文件傳送協議。可以為傳輸文件提供一種安全的加密方法。

sftp 與 ftp 有着幾乎一樣的語法和功能。

SFTP 為 SSH的一部份，是一種傳輸檔案至 Blogger 伺服器的安全方式。

其實在SSH軟件包中，已經包含了一個叫作SFTP(Secure File Transfer Protocol的安全文件傳輸子系統，SFTP本身沒有單獨的守護進程，它必須使用sshd守護進程（端口號默認是22）來完成相應的連接操作，所以從某種意義上來說，SFTP並不像一個服務器程序，而更像是一個客戶端程序。SFTP同樣是使用加密傳輸認證信息和傳輸的數據，所以，使用SFTP是非常安全的。

但是，由於這種傳輸方式使用了加密/解密技術，所以傳輸效率比普通的FTP要低得多，如果您對網絡安全性要求更高時，可以使用SFTP代替FTP。

 2.1 cmd命令行實例

E:\SFTP>psftp.exe username@172.0.0.1 -i privatekey.ppk

The server's host key is not cached in the registry. You

have no guarantee that the server is the computer you

think it is.

The server's rsa2 key fingerprint is:

ssh-rsa 2048 0a:**:**:**:54:**:82:**:**:1f:**:**:**:87:30:**

If you trust this host, enter "y" to add the key to

PuTTY's cache and carry on connecting.

If you want to carry on connecting just once, without

adding the key to the cache, enter "n".

If you do not trust this host, press Return to abandon the

connection.

Store key in cache? (y/n) n

Using username "sobne".
