convert_stellarHash     Convert hash on STELLAR network (base64
                        encoded) to standard hexadecimal value
create_hashFile         Create sha256 hash of a file
create_hashObject       Create sha256 hash of an object/dataset
create_ttsFile          Create trusted timestamp of a file
create_ttsObject        Create trusted timestamp of an object/dataset
get_hash                Retrieve hash from STELLAR network
get_timestamp           Retrieve timestamp from STELLAR network

validate_hashFile       Validate hash of a file (created on the fly)
                        with hash on STELLAR network p.s. stellar
                        transactions take between 5-7 seconds. If you
                        validate to soon after creating a timestamp, it
