    DES S-Box

    Someone is able to explain in detail the construction and operation of the DES S-Box, which from n input bits input, produces an output of m bits, with m <n?
    How can I get these properties?
    The process is reversible? How can I get the initial bits from those produced by the S-Box?

    Thanks in advance for your answers.
