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.
