(JavaScript) SFTP Host Key Fingerprint

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var sftp = new CkSFtp();

var hostname = "sftp.example.com";
var port = 22;
success = sftp.Connect(hostname,port);

    console.log(sftp.LastErrorText);
    return;
}

// Get the classic MD5 fingeprint
var md5_fingerprint = sftp.HostKeyFingerprint;

// Sample output:
// ssh-rsa 3072 21:b0:d8:41:4e:ef:78:10:20:af:01:b7:71:5d:eb:94

// Starting in Chilkat v9.5.0.92, we can also get the SHA256 fingerprint.
// (it is also possible to get fingerprints using other hash algorithms such as SHA384, SHA512, etc.)
