loSshkey = createobject("CkSshKey")

// First, use the LoadText convenience method to load a text file (of any SSH key format)
// into a string:
lcStrKey = loSshkey.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.)
llSuccess = loSshkey.FromOpenSshPrivateKey(lcStrKey)
if (llSuccess <> .T.) then
    ? loSshkey.LastErrorText
else
    ? "Loaded OpenSSH private key."
    release loSshkey
    return
endif

// If the key is an OpenSSH public key:
llSuccess = loSshkey.FromOpenSshPublicKey(lcStrKey)
if (llSuccess <> .T.) then
    ? loSshkey.LastErrorText
else
    ? "Loaded OpenSSH public key."
    release loSshkey
    return
endif

// If the key is a PuTTY private key:
llSuccess = loSshkey.FromPuttyPrivateKey(lcStrKey)
if (llSuccess <> .T.) then
    ? loSshkey.LastErrorText
else
    ? "Loaded PuTTY private key."
    release loSshkey
    return
endif

// If the key is an RFC 4716 public key:
llSuccess = loSshkey.FromRfc4716PublicKey(lcStrKey)
if (llSuccess <> .T.) then
    ? loSshkey.LastErrorText
else
    ? "Loaded RFC 4716 public key."
