$key = New-Object 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 -ne $true) {
    $($key.LastErrorText)
    exit
}

#  Generate the fingerprint:

$fingerprint = $key.GenFingerprint()

$($fingerprint)

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