Obtaining host key fingerprint

When connecting to an SSH server for the first time you may not know what the host key fingerprint is, and without knowing the ssh host key fingerprint you will be unable to validate the host key. The following code example demonstrates how to connect to an SSH server and obtain the host key fingerprint.

Example

[C#]

// create login credentials

SshParameters sshParams = new SshParameters(hostname,username,password);

// create new Ssh instance

Ssh ssh = new Ssh(sshParams);

// set your license key

ssh.LicenseKey = "license key data";

// establish connection

ssh.Connect();

// obtain host keys for connection

SshHostKeys hostKeys = ssh.HostKeys;

// get all hosts for SshHostKeys

IEnumerator hosts = hostKeys.GetHosts();

// iterate thru each host

while (hosts.MoveNext())

{

DictionaryEntry host = (DictionaryEntry)hosts.Current;

IPHostEntry ip = (IPHostEntry)host.Key;

// print host

Console.WriteLine("Found host {0}", ip.HostName);

// print fingerprints for host

IEnumerator fingerprints = hostKeys.GetKeys(ip);

while (fingerprints.MoveNext())

{

string fingerprint = (string)fingerprints.Current;

Console.WriteLine("Fingerprint found {0}", fingerprint);

}
