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

    //  into a string:
    strKey = CkSshKey_loadText(sshkey,"../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.)
