Load an SSH Key from a File (Many Formats Supported)

Demonstrates how to load an SSH public or private key object from a file. The file can be in any of the following formats:

• OpenSSH private key
• OpenSSH public key
• PuTTY private key
• RFC 4716 public key

function chilkatExample() {

    var success = false;

    var sshkey = new chilkat.SshKey();

    //  First, use the LoadText convenience method to load a text file (of any SSH key format)
    //  into a string:
    var strKey = sshkey.LoadText("../mySshKeys/myKey.txt");

    //  Next, load the key into the SSH key object.

    //  If the key is an OpenSSH private key:
    //  (In actuality, the From* methods will automatically detect the format and load
    //  the key correctly.  For example, if a PuTTY private key is passed to FromOpenSshPrivateKey,
    //  it  will still load correctly.)
    success = sshkey.FromOpenSshPrivateKey(strKey);
    if (success !== true) {
        console.log(sshkey.LastErrorText);
    }
    else {
        console.log("Loaded OpenSSH private key.");
        return;
    }

    //  If the key is an OpenSSH public key:
    success = sshkey.FromOpenSshPublicKey(strKey);
    if (success !== true) {
        console.log(sshkey.LastErrorText);
    }
    else {
        console.log("Loaded OpenSSH public key.");
        return;
    }

    //  If the key is a PuTTY private key:
    success = sshkey.FromPuttyPrivateKey(strKey);
    if (success !== true) {
        console.log(sshkey.LastErrorText);
    }
    else {
        console.log("Loaded PuTTY private key.");
        return;
    }

    //  If the key is an RFC 4716 public key:
    success = sshkey.FromRfc4716PublicKey(strKey);
    if (success !== true) {
