Procedure ChilkatExample()

    success.i = 0

    ; This example requires the Chilkat API to have been previously unlocked.
    ; See Global Unlock Sample for sample code.

    ssh.i = CkSsh::ckCreate()
    If ssh.i = 0
        Debug "Failed to create object."
        ProcedureReturn
    EndIf

    ; To get the authentication methods offered by an SSH server, we first connect.
    success = CkSsh::ckConnect(ssh,"example.com",22)
    If success <> 1
        Debug CkSsh::ckLastErrorText(ssh)
        CkSsh::ckDispose(ssh)
        ProcedureReturn
    EndIf

    ; Next, we call GetAuthMethods to receive a comma separated list of authentication methods
    authMethods.s = CkSsh::ckGetAuthMethods(ssh)
    If CkSsh::ckLastMethodSuccess(ssh) <> 1
        Debug CkSsh::ckLastErrorText(ssh)
        CkSsh::ckDispose(ssh)
        ProcedureReturn
    EndIf

    ; For example: publickey,password,keyboard-interactive
    Debug "Authentication methods suported by this serve: " + authMethods

    ; IMPORTANT:
    ; Getting the authentication methods will intentionally disconnect from the server.
    ; We'll need to re-connect, etc. to continue..

    ; For example..
    success = CkSsh::ckConnect(ssh,"example.com",22)
    If success <> 1
        Debug CkSsh::ckLastErrorText(ssh)
        CkSsh::ckDispose(ssh)
        ProcedureReturn
    EndIf

    success = CkSsh::ckAuthenticatePw(ssh,"myLogin","myPassword")
    If success <> 1
        Debug CkSsh::ckLastErrorText(ssh)
        CkSsh::ckDispose(ssh)
        ProcedureReturn
    EndIf

    Debug "SSH Authentication successful."

    ; ...

    CkSsh::ckDisconnect(ssh)


    CkSsh::ckDispose(ssh)


    ProcedureReturn
EndProcedure
