Generates a fingerprint for an SSH key.

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.

JavaScript

var success = false;

var key = new CkSshKey();

// Load an SSH key from an encrypted OpenSSH-formatted private key:
key.Password = "secret";

var keyStr;
// First load the PEM into a string:
keyStr = key.LoadText("privkey_openssh_encrypted.pem");

// Import into the SSH key object:
success = key.FromOpenSshPrivateKey(keyStr);
if (success !== true) {
    console.log(key.LastErrorText);
    return;
}

// Generate the fingerprint:
var fingerprint;
fingerprint = key.GenFingerprint();

console.log(fingerprint);

// A sample fingerpring looks like this:
// ssh-dss 2048 d0:5f:f7:d6:49:60:7b:50:19:f4:41:59:d4:1f:61:7
