SFTP即加密文件传输协议(Secure file transfer protocol) ，与FTP不同的是，指令与数据在传输过程中都是经过加密的，防止在网络传输过程中密码和敏感信息被盗取。为了使用.Net来实现这一过程： 1.安装SFTP Server测试环境： 下载setupssh.exe 在服务器上按照提示安装setupssh.exe 打开一个命令行，找到OpenSSH目录（默认：C:Program FilesOpenSSH） 创建Group mkgroup -l >> .etcgroup 创建User mkpasswd -l >> .etcpasswd 注:创建group和User请参考安装目录的readme.txt 2.下载SampleCode 3.新建一个工程，引用SampleCode中的Tamir.sharpSsh.dll，Org.Mentalis.Security.dll，DiffieHellman.dll (SFTP that encrypted file transfer protocol (Secure file Transfer protocol) and FTP, the instruction and data during transmission are encrypted, preventing passwords and sensitive information was stolen during a network transfer. In order to use NET to implement this process: 1. Install SFTP Server test environment: Download setupssh.exe on the server, follow the prompts to install setupssh.exe open a command line, find the OpenSSH directory (default: C: Program Files OpenSSH) The create Group mkgroup-l > > . etcgroup create the User mkpasswd-l > > . etcpasswd Note: Create the group and User Please refer to the installation directory of readme.txt 2 downloads SampleCode create a new project, to reference SampleCode Tamir.sharpSsh. dll, Org.Mentalis.Security.dll, DiffieHellman.dll)
