* testsuite/serpent-test.m4: Added a few rudimentary tests
extracted from the serpent package.
* twofish.c: Adapted to nettle. Made constant tables const.
Deleted bytes_to_word and word_to_bytes; use LE_READ_UINT32 and
LE_WRITE_UINT32 instead.
(twofish_selftest): Deleted. Moved the tests to the external
testsuite.
(twofish_set_key): Don't silently truncate too large keys.
* sha1.c (sha1_update): Use unsigned for length.
* serpent.c (serpent_set_key): Read the key backwards. Fixed
padding (but there are no test vectors for key_size not a multiple
of 4).
(serpent_encrypt): Read and write data in the strange order used
by the reference implementation.
(serpent_decrypt): Likewise.
* macros.h (FOR_BLOCKS): New macro, taken from lsh.
* blowfish.h (struct blowfish_ctx): Use a two-dimensional array
for s.
* blowfish.c (initial_ctx): Arrange constants into a struct, to
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.
* Makefile.am (libnettle_a_SOURCES): Added twofish.
2001-06-16 Niels Möller <nisse@cuckoo.hack.org>
* testsuite/blowfish-test.m4: Fixed test.
* Added twofish implementation.
* blowfish.h (struct blowfish_ctx): Use the correct size for the p
array.
* testsuite/blowfish-test.m4: Fixed testcase, use correct key
length.
* Makefile.am (libnettle_a_SOURCES): Added blowfish files.
($(des_headers)): Strip directory part when passing file name to
desdata.
* testsuite/blowfish-test.m4: Added one test, from GNUPG.
* Created blowfish.c and blowfish.h (from GNUPG via LSH). Needs
more work.
* aes.h: Fixed copyright notice to not mention GNU MP. XXX: Review
all nettle copyrights.
* testsuite/Makefile.am (TS_PROGS): Added tests for twofish and
blowfish.
2001-06-13 Niels Möller <nisse@ehand.com>
* Makefile.am (libnettle_a_SOURCES): Added serpent files.
2001-06-12 Niels Möller <nisse@cuckoo.hack.org>

successful.

2001-04-17 Niels Möller <nisse@cuckoo.hack.org>
* install-sh: Copied the standard install script.
* testsuite/Makefile.am (CFLAGS): Disable optimization. Add
$(top_srcdir) to the include path.
(EXTRA_DIST): Added testutils.h, testutils.c and run-tests.
(run-tests): Fixed path to run-tests.
* Makefile.am (EXTRA_DIST): Added memxor.h.
