SSH Key Fingerprint

Generates a fingerprint for an SSH key.

Download: Chilkat .NET Assemblies

Chilkat.SshKey key = new Chilkat.SshKey();

bool success;

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

string 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) {
    MessageBox.Show(key.LastErrorText);
    return;
}

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

textBox1.Text += fingerprint + "\r\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
