ChangeLog 82.10 KiB
2004-01-08 Niels Mller <niels@s3.kth.se>
* 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 Mller <nisse@harpo.hack.org>
* nettle-types.h: New (generated) file, to be used instead of
including <inttypes.h> directly. Updated all users of inttypes.h.
* Makefile.am (DISTCLEANFILES, libnettleinclude_HEADERS): Added
nettle-types.h.
* configure.ac (AX_CREATE_STDINT_H): Create nettle-types.h.
2003-11-16 Niels Mller <nisse@harpo.hack.org>

2003-11-12 Niels Mller <niels@s3.kth.se>
* list-obj-sizes.awk: New function for decoding hex values, with a
new function hex2int. Also implemented calculation of total
storage, removed the dependence on the .comment section, and use
the $FILTER environment variable as a regexp for restricting the
object files that are considered.
2003-09-21 Niels Mller <nisse@cuckoo.hack.org>
* testsuite/rsa-encrypt-test.c (test_main): Don't use gmp_printf,
as it seems it's only available with the newer gmp. Use
mpz_out_str instead.

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

* 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 Mller <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.
* des-compat.c (des_key_sched, des_is_weak_key): Use the name
nettle_des_set_key for referring to Nettle's function.
* des.h (des_set_key): Name mangling, linker symbols should use a
"nettle_" prefix, and this one collided with openssl. Perhaps all
symbols should be mangled in a similar way, but that's for later.
* configure.ac (LDFLAGS): --with-lib-path should add to LDFLAGS,
not replace it.
2003-01-30 Niels Mller <nisse@cuckoo.hack.org>

encrypt more than one block at a time.
2002-05-07 Niels Mller <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.
Fixed the processing of the first handling of the round function.
Now, encryption of a single block works! Multiple blocks, and
decryption, is still broken.

2002-02-25 Niels Mller <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,

get to the current roundkey.

* 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 Mller <nisse@cuckoo.hack.org>

loop variable.
(_aes_crypt): Started renumbering registers in the inner loop. The

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.

of yet another redundant loop variable, and one instruction.

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.

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