2013-05-28  Niels Möller  <nisse@lysator.liu.se>

* Released nettle-2.7.1.

2013-05-21  Niels Möller  <nisse@lysator.liu.se>

From master (2013-05-20):
	* arm/v6/sha1-compress.asm: Moved into v6 directory, since it uses
	the v6 instruction uadd8, sel and rev.
	* arm/v6/sha256-compress.asm: Likewise.

From master (2013-05-15):
	* configure.ac (asm_path): Handle armv6 and armv7 differently from
	older ARMs. Add the arm/v6 directory to asm_path when appropriate.

* arm/v6/aes-encrypt-internal.asm: Moved into v6 directory. Uses
	the uxtb instruction which is not available for older ARMs.
	* arm/v6/aes-decrypt-internal.asm: Likewise.

2013-05-21  Niels Möller  <nisse@lysator.liu.se>

* configure.ac: Changed version number to 2.7.1.
	(LIBHOGWEED_MINOR): Bumped library version, to 4.7.
	(LIBHOGWEED_MINOR): And to 2.5.

	* ecc-j-to-a.c (ecc_j_to_a): Fixed ecc_modp_mul call, to avoid
	invalid overlap of arguments to mpn_mul_n. Problem tracked down by
	Magnus Holmgren.

2013-04-24  Niels Möller  <nisse@lysator.liu.se>

	* examples/Makefile.in, tools/Makefile.in, testsuite/Makefile.in:
	Likewise.

	(UPDATED-FOR): Set to 1.11. I think the manual should be updated
	with all user-visible changes.

* aclocal.m4 (LSH_DEPENDENCY_TRACKING): Need extra quoting in case
	pattern. (This file really lives in the lsh tree, as
	lsh/acinclude.m4. For a complete ChangeLog, see lsh/Changelog).

* examples/nettle-openssl.c (NCOMPAT): Disable openssl backwards
	compatibility.

	precomputing the offset between src and dst.

* tools/Makefile.in (.c.$(OBJEXT)): Removed redundant -I.. flag.

* x86/arcfour-crypt.asm (nettle_arcfour_crypt): Replaced addb ->

	/dev/urandom.

2004-02-12  Niels Möller  <niels@s3.kth.se>

* configure.ac (CPPFLAGS, LDFLAGS): No spaces after -I and -L, as

	is unavailable, they work by allocating a fix amount of stack and
	imposing a hard limit on what can be allocated. Updated all users

2003-09-21  Niels Möller  <nisse@cuckoo.hack.org>

* testsuite/rsa-encrypt-test.c (test_main): Don't use gmp_printf,

	nettle_des_set_key for referring to Nettle's function.

* x86/aes-encrypt.asm (aes_encrypt): Use test instead of cmpl $0,.

* 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>

	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

	(_aes_crypt): Renamed variables in source_loop.

	(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/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.

	decryption.

AES key setup now uses two separate functions for setting
	encryption and decryption keys. Applications that don't do

	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.

* configure.in: Fixed spelling of --enable-assembler. Commented

* configure.in: New command line option --enable-assembler.
	Selects assembler code depending on the host system.

* rsa-decrypt.c, rsa-encrypt.c: New files for rsa pkcs#1
	encryption.

* aes-set-key.c, aes-tables.c: New files, split off from aes.c.
	Tables are now not static, but use a _aes_ prefix on their names.

* aes-internal.h: New file.

* cast128-meta.c (_NETTLE_CIPHER_FIX): Use _NETTLE_CIPHER_FIX.

* cbc.c (cbc_decrypt_internal): New function, doing the real CBC
	procesing and requiring that src != dst.
	(cbc_decrypt): Use cbc_decrypt_internal. If src == dst, use a
	buffer of limited size to copy the ciphertext.

* nettle-internal.c (nettle_blowfish128): Fixed definition, with
	key size in bits.

* nettle-meta.h (_NETTLE_CIPHER_FIX): New macro, suitable for
