NSMutableString *strOutput = [NSMutableString stringWithCapacity:1000];

CkoSshKey *key = [[[CkoSshKey alloc] init] autorelease];

BOOL success;

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

NSString *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 != YES) {
    [strOutput appendString: key.LastErrorText];
    [strOutput appendString: @"\n"];
    self.mainTextField.stringValue = strOutput;
    return;
}

//  Generate the fingerprint:
NSString *fingerprint;
fingerprint = [key GenFingerprint];

[strOutput appendString: fingerprint];
[strOutput appendString: @"\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
