SSH主机密钥指纹与模式C#WinSCP不匹配
作者:互联网
我试图通过WinSCP使用C#连接到FTPS服务器,我收到此错误:
SSH host key fingerprint … does not match pattern …
经过大量的研究,我认为这与关键的长度有关.当我使用“服务器和协议信息”下的接口连接时从WinSCP获得的密钥是
xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx但我在示例中看到的更短像这个xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
有人可以请帮助,并提供任何指针,以解决这一点将不胜感激.
这是我的代码
string winscpPath = "C:\\Program Files (x86)\\WinSCP\\WinSCP.exe";
string username = "User123";
string password = "abc1234";
string ftpSite = "192.168.5.110";
string localPath = "C:\\Users\\ttom\\Documents";
string remoteFTPDirectory = "/Usr/thisfolder";
string sshKey = "1b:68:10:80:77:c6:65:91:51:31:5t:65:1c:g6:13:20:39:g8:d8:6d";
Boolean winSCPLog = true;
string winSCPLogPath = "C:\\Users\\ttom\\Documents\\Visual Studio 2015\\Projects\\WebApplication1\\WebApplication1";
SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Sftp,
HostName = ftpSite,
UserName = username,
Password = password,
SshHostKeyFingerprint = sshKey
};
using (Session session = new Session())
{
// WinSCP .NET assembly must be in GAC to be used with SSIS,
// set path to WinSCP.exe explicitly, if using non-default path.
session.ExecutablePath = winscpPath;
session.DisableVersionCheck = true;
if (winSCPLog)
{
session.SessionLogPath = @winSCPLogPath + @"ftplog.txt";
session.DebugLogPath = @winSCPLogPath + @"debuglog.txt";
}
// Connect
session.Timeout = new TimeSpan(0, 2, 0); // two minutes
session.Open(sessionOptions);
TransferOptions transferOptions = new TransferOptions();
transferOptions.TransferMode = TransferMode.Binary;
session.GetFiles(remoteFTPDirectory + "/" +
"test.txt", localPath, false, transferOptions);
}
解决方法:
您正在使用代码中的SFTP(通过SSH)进行连接,但在GUI中使用FTPS(FTP over TLS / SSL).
这是两个completely different protocols.
使用Protocol = Protocol.Ftp
并使用FtpSecure = FtpSecure.Explicit
启用TLS / SSL.
SessionOptions sessionOptions = new SessionOptions
{
Protocol = Protocol.Ftp,
FtpSecure = FtpSecure.Explicit,
HostName = ftpSite,
UserName = username,
Password = password,
};
FTPS的等效SshHostKeyFingerprint是TlsHostCertificateFingerprint
.但是,只有当TLS / SSL证书未由受信任的机构(例如自签名证书)签名时,才需要使用它.
最简单的是为你准备WinSCP GUI generate code.
