	string. 

2003-02-06  Niels Möller  <nisse@lysator.liu.se>
	
	* testsuite/sexp-conv-test (print_raw, print_nl): New functions.
	The testfunctions use these instead of using echo directly.

2003-02-05  Niels Möller  <nisse@lysator.liu.se>

	nettle_des_set_key for referring to Nettle's function.

	not replace it.

	* x86/machine.m4 (AES_SUBST_BYTE): New macro.

	* sparc/aes.asm: wtxt needs no register of it's own, as its

	allocated for wtxt, so that we stay clean of the reserved %g
	registers.

2002-05-14  Niels Möller  <nisse@cuckoo.hack.org>

	* sparc/aes.asm: Avoid using %g6 and %g7, as they are reserved for

	references to dtbl1-4 with references to _aes_encrypt_table.

	* configure.ac (asm_path): Enable x86 assembler.

	* x86/aes.asm (aes_decrypt): Adapted to the current interface.
	Notably, the order of the subkeys was reversed. Single block
	encrypt/decrypt works now.
	(aes_encrypt, aes_decrypt): Added an outer loop, so that we can
	encrypt more than one block at a time.

2002-05-07  Niels Möller  <niels@s3.kth.se>

	* configure.ac: Generate config.m4.

	* x86/aes.asm: Use C for comments, include the tables using
	include_src, and commented out the key setup functions.

2002-02-25  Niels Möller  <nisse@cuckoo.hack.org>

	* sparc/aes.asm (_aes_crypt): Moved increment of src into the
	source_loop. Also fixed stop condition, the loop was run 5 times,

	don't use %o5.
	(_aes_crypt): Renamed variables in source_loop.

	faster... 

	* sparc/aes.asm (_aes_crypt): Use double-buffering, and no
	separate loop for adding the round key.
	(round): Keep round index muliplied by 16, so it can be used
	directly for indexing the subkeys.

	(_aes_crypt): In final_loop, deleted a redundant mov, and use i as
	loop variable.
	(_aes_crypt): Started renumbering registers in the inner loop. The
	computation for the table[j] sub-expression should be kept in
	register %o[j].
	(_aes_crypt): Renamed more variables in the inner loop. Now the
	primary variables are t0, t1, t2, t3.

	* sparc/aes.asm (_aes_crypt): Swapped register %i0 and %o5, %i1
	and %o0, %i2 and %o4, %i3 and %o3, %i4 and %o2.
	(_aes_crypt): wtxt was stored in both %l1 and %l2 for the entire
	function. Freed %l2 for other uses.
	(_aes_crypt): Likewise for tmp, freeing register %o1.	

	* sparc/machine.m4: New file, for sparc-specific macros.

	* sparc/aes.asm (_aes_crypt): Hacked the source_loop, to get rid
	of yet another redundant loop variable, and one instruction.
	(_aes_crypt): Strength reduce loop variable in the
	inner loop, getting rid of one register.
	(_aes_crypt): Use pre-shifted indices (aes_table.idx_shift), to
	avoid some shifts in the inner loop.
	(_aes_crypt): Don't check for nrounds==0 at the start of the loop.

	* asm.m4: Define and use structure-defining macros.

	* Makefile.am (%.asm): Use a GNU pattern rule, to make %.o depend
	on both %.asm and asm.m4.

	* aes-internal.h (struct aes_table): New subtable idx_shift.
	Updated tables in aes_encrypt.c and aes_decrypt.c.

	* asm.m4: Use eval to compute values.

	* sparc/aes.asm (_aes_crypt): Deleted commented out old version of

	* aes-internal.h (struct aes_table): New structure, including all
	constant tables needed by the unified encryption or decryption
	function _aes_crypt.

	* aes.c (_aes_crypt): New function, which unifies encryption and
	decryption.

	AES key setup now uses two separate functions for setting
	encryption and decryption keys. Applications that don't do
	decryption need no inverted subkeys and no code to generate them.
	Similarly, the tables (about 4K each for encryption and
	decryption), are put into separate files.

	* aes.h (struct aes_ctx): Deleted space for inverse subkeys. For
	decryption, the inverse subkeys replace the normal subkeys, and
	they are stored _in the order they are used_.

	of one register and one instruction in the inner loop.

	* sparc/aes.asm (idx, aes_encrypt): Multiplied tabled values by 4,
	making it possible to get rid of some shifts in the inner loop.

	(info_TEXINFOS): Added manual.
	(EXTRA_DIST): Added nettle.html.
	(%.html): Added rule for building nettle.html.

	* nettle.texinfo: New manual.

	* configure.in: Bumped version to 0.2.

	* testsuite/Makefile.am (TS_PROGS): Added cast128 test.

	* Added CAST128.

	* 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.

	array.

	* testsuite/blowfish-test.m4: Fixed testcase, use correct key
	length. 

	* Makefile.am (libnettle_a_SOURCES): Added blowfish files.

	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.
