// First, use the LoadText convenience method to load a text file (of any SSH key format)
// into a string:
Dim strKey As String

// 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

// it  will still load correctly.)
