# Test vectors for Skipjack

# --- From the Skipjack definition ---

skipjack {

  # --- The official Skipjack test vector ---
  #
  # It's a bit piss-poor that they only provide one test-vector here.

  # --- From KEA test vectors ---
  #
  # The Skipjack algorithm is used by the KEA to derive the final key.
  # Unfortunately, the test vectors given in the Skipjack/KEA spec don't
  # match my (or anyone else's!) implementation.  These are the values
  # which seem to be generally agreed.

  # test the F-table.  There are 16 entries unaccounted for.  The keys and
  # plaintexts were generated using fibrand with seed 0.
