      * blowfish.c (initial_ctx): Arrange constants into a struct, to · 478484e6
      Niels Möller authored
      simplify key setup.
      (F): Deleted all but one definitions of the F function/macro.
      Added a context argument, and use that to find the subkeys.
      (R): Added context argument, and use that to find the subkeys.
      (blowfish_set_key): Some simplification.
      
      (encrypt): Deleted code for non-standard number of rounds. Deleted
      a bunch of local variables. Using the context pointer for
      everything should consume less registers.
      (decrypt): Likewise.
