<?php


$key = new COM("Chilkat.SshKey");

//  Load an SSH key from an encrypted OpenSSH-formatted private key:
$key->Password = 'secret';

//  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) {
    print $key->lastErrorText() . "\n";
    exit;
}

//  Generate the fingerprint:

$fingerprint = $key->genFingerprint();

print $fingerprint . "\n";

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