    + added PRG functions for BlowFish encryption:
         hb_blowfishKey( <cPass> ) -> <bfKey>
         hb_blowfishEncrypt( <bfKey>, <cData> ) -> <cCryptedData>
         hb_blowfishDecrypt( <bfKey>, <cCryptedData> ) -> <cData>
      On errors above functions return NIL.
      Warning: the size of encrypted data is padded to 64bit (8 bytes)
      so it's bigger then original one.
