Cipher modes, describing both CBC and the new CTR mode.

* x86/sha1-compress.asm (OFFSET): New macro.
(F3): Eliminated a movl.
(ROUND): New argument, for k. When using F3, it's TMP3, on the

conversion, and store the input data on the stack. This leaves one
more register free for other uses.
* examples/nettle-benchmark.c: Now display cycles/byte, if the -f
option is used to say what the clock frequency is.

argument is now a pointer to the input data in unaligned,
big-endian form.
2005-09-28 Niels Möller <niels@s3.kth.se>

need to include <unistd.h>.
2004-03-01 Niels Möller <niels@s3.kth.se>
* config.guess: Copied from automake-1.8.2. Hacked to recognize
Windows_NT (and Windows_95 and Windows_98) running on "x86" and

* nettle-meta.h (nettle_crypt_func): Typedef moved to cbc.h.
Include cbc.h instead.

* configure.ac (CPPFLAGS, LDFLAGS): No spaces after -I and -L, as
some C compilers, in particular True64 cc, don't like that.
2004-02-08 Niels Möller <nisse@lysator.liu.se>
* configure.ac: Bumped version number to 1.10.
2004-02-07 Niels Möller <nisse@lysator.liu.se>

des_ecb_encrypt, cst arguments to (void *). Openssl's typedefs
des_cblock and const_des_cblock are too broken.

* testsuite/testutils.c (test_cipher_stream): New function, that
tries dividing the input into varying size blocks before
processing.
* x86/arcfour-crypt.asm (nettle_arcfour_crypt): Bug fix, half of
the S array swap was forgotten.
* arcfour.c (arcfour_stream): Likewise.
* arcfour-crypt.c (arcfour_crypt): Likewise.

* arcfour.c (arcfour_crypt): Moved function too...
* arcfour-crypt.c (arcfour_crypt): New file.
* arcfour.c (arcfour_crypt): Optimization suggested by Jonas

probably on other architectures as well.
2004-01-31 Niels Möller <nisse@lysator.liu.se>
* configure.ac (AX_CREATE_STDINT_H): Also look for uint32_t and
friends in sys/types.h.
2004-01-11 Niels Möller <nisse@harpo.hack.org>

* rsa-keygen.c (bignum_next_prime): Fixed off-by-one error when
comparing input to the largest listed prime. General cleanup, as
prime_limit > 0 always. Use TMP_DECL and TMP_ALLOC.
* nettle-internal.h (TMP_DECL, TMP_ALLOC): New macros. When alloca
is unavailable, they work by allocating a fix amount of stack and
imposing a hard limit on what can be allocated. Updated all users
of alloca.
2004-01-07 Niels Möller <nisse@harpo.hack.org>

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

* examples/Makefile.am (EXTRA_DIST): Added rsa-session.h.
* tools/nettle-lfib-stream.c: New tool, which outputs a sequence

won't work yet.
* examples/Makefile.am (EXTRA_PROGRAMS): Added rsa-encrypt and
rsa-decrypt.

Nettle's des functions.
* base16-meta.c (base16_encode_update): Need to undef before
redefining.
* New name mangling, to reduce the risk of link collisions. All
functions (except memxor) now use a nettle_ or _nettle prefix when
seen by the linker. For most functions, the header file that

readable name without the prefix.
2003-03-11 Niels Möller <nisse@cuckoo.hack.org>
* Released nettle-1.7.

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.
Use the test input '3:"\x' instead of '2:"\', to be friendlier to
sysv echo.
2003-02-05 Niels Möller <nisse@lysator.liu.se>
* des-compat.h (des_set_key): Different name mangling, if this
file is included, des_set_key should refer to a function that
behaves like openssl's.

2002-02-22 Niels Möller <nisse@cuckoo.hack.org>
* sparc/aes.asm (_aes_crypt): Moved some more additions out of the
inner loop, using additional registers.

using the subkey pointer.
2002-02-19 Niels Möller <nisse@cuckoo.hack.org>

* sparc/aes.asm: Use that IDX2(j) == j ^ 2
* Makefile.am (libnettle_a_SOURCES): Reordered aes-decrypt.c and
aes-encrypt.c. For some strange reason it makes the benchmark go
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 the final loop, use ctx+round to access the
subkeys, no need for an extra register.
2002-02-15 Niels Möller <nisse@cuckoo.hack.org>
* sparc/aes.asm (_aes_crypt): Renaming variables, allocating
locals starting from %l0.
(_aes_crypt): Consistently use %l4, aka i, as the variable for the
innermost loops.
(_aes_crypt): Moved reading of ctx->nrounds out of the loop.
(_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.

on both %.asm and asm.m4.

and aes_set_decrypt_key.

arguments.

constant tables needed by the unified encryption or decryption
function _aes_crypt.

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_.
* aes-set-key.c (aes_set_key): Deleted file, code moved...
* aes-set-decrypt-key.c, aes-set-encrypt-key.c: New files,
separated normal and inverse key setup.

decryption funktions, and needed tables, into separate files.

avoid rotates.
* sparc/aes.asm (aes_encrypt): Strength reduced on j, getting rid
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
out debug echo:s.
* asm.m4: New file. For now, only doing changequote and changecom.
* sparc/aes.asm (aes_encrypt): Added comments.
(aes_encrypt): Cut off redundant instruction per block, also
saving one redundant register pointing to idx.

* 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.

key size in bits.
* nettle-meta.h (_NETTLE_CIPHER_FIX): New macro, suitable for
ciphers with a fixed key size.
* examples/nettle-benchmark.c (display): New function for
displaying the results, including MB/s figures.

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 Möller <nisse@cuckoo.hack.org>

(R): Added context argument, and use that to find the subkeys.
(blowfish_set_key): Some simplification.
