Spotted by Jean-Pierre. (twofish_encrypt): Likewise. 2001-07-03 Niels M�ller <nisse@ehand.com> * testsuite/testutils.c: Include string.h. * twofish.c: Include string.h. 2001-06-17 Niels M�ller <nisse@lysator.liu.se> * Makefile.am (des_headers): Dont use $(srcdir)/-prefixes as that seems to break with GNU make 3.79.1. * testsuite/testutils.c, testsuite/testutils.h: Use <inttypes.h>, not <stdint.h>. Include <stdlib.h>. 2001-06-17 Niels M�ller <nisse@cuckoo.hack.org> * Use <inttypes.h>, not <stdint.h>. * blowfish.h (BLOWFISH_MAX_KEY_SIZE): Fixed, should be 56. * Fixed copyright notices. * Makefile.am (libnettle_a_SOURCES): Added desinfo.h and desCode.h.

(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.
