ChangeLog

2004-02-17  Niels Mller  <niels@s3.kth.se>

	* Makefile.am: Protected %-rules used for building pure objects,
	and for assembler files, by automake conditionals. Needed for
	makes such as tru64's, which tries to understand %-patterns, but
	doesn't get it right.
	(SUFFIXES): Added .html.
	(.texinfo.html): Rewrote rule to use a traditional suffix target.
	
	* configure.ac (enable_assembler): Explicitly set
	enable_assembler=no, on architectures where we have no assembler
	files. 
	(ENABLE_ASSEMBLER, ENABLE_SHARED): New automake conditionals.

	* testsuite/testutils.c (xalloc): xalloc(0) should work also on
	systems where malloc(0) returns NULL.

2004-02-16  Niels Mller  <niels@s3.kth.se>

	* Makefile.am (%.o: %.asm): Added comment about OSF1 make problem.

2004-02-15  Niels Mller  <nisse@lysator.liu.se>

	* testsuite/testutils.h: #include nettle-types.h instead of
	inttypes.h. 

2004-02-12  Niels Mller  <nisse@lysator.liu.se>

	* examples/rsa-encrypt-test: Use -r option when invoking
	rsa-encrypt. Needed for the test to work on systems with no
	/dev/urandom.

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

	* 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 Mller  <nisse@lysator.liu.se>

	* configure.ac: Bumped version number to 1.10.

2004-02-07  Niels Mller  <nisse@lysator.liu.se>

	* Released nettle-1.9.

	* configure.ac (SHLIBMINOR): Bumped, library version is now 2.1.

	* testsuite/sexp-format-test.c: Include bignum.h only if HAVE_LIBGMP.
	* testsuite/rsa-encrypt-test.c: Include rsa.h only if WITH_PUBLIC_KEY.
	* testsuite/pkcs1-test.c: Include pkcs1.h only if WITH_PUBLIC_KEY.

	* pgp-encode.c [!HAVE_LIBGMP]: Kludge around the pgp.h's
	dependency on gmp.h.
	(pgp_put_mpi): Condition on HAVE_LIBGMP.

	* pgp.h: Don't include bignum.h, to make it possible to compile
	the non-bignum parts of pgp-encode.c without bignum support. Needs
	to be fixed properly before the pgp interface is advertised.

	* tools/sexp-conv.c (xalloc): New function.
	(main): Use xalloc.

	* tools/output.c (sexp_put_digest): Use TMP_DECL instead of alloca.

	functions use xalloc instead of alloca.

	* testsuite/bignum-test.c (test_bignum): Likewise.

	* examples/nettle-openssl.c: When calling des_key_sched and
	des_ecb_encrypt, cst arguments to (void *). Openssl's typedefs
	des_cblock and const_des_cblock are too broken.

	* examples/nettle-benchmark.c (xalloc): New function. Use instead
	of alloca, for better portability.

	* examples/io.c (xalloc): New function.

	* Makefile.am (nodist_libnettleinclude_HEADERS): nettle-types.h
	should not be distributed.

2004-02-06  Niels Mller  <niels@s3.kth.se>

	* x86/sha1-compress.asm: Rename round -> ROUND.

	* x86/sha1-compress.asm: Store the magic constants on stack.
	Accessing them via %esp should be a little faster than using large
	immediate operands.

	* Makefile.am (EXTRA_DIST, DISTCLEANFILES): Handle
	sha1-compress.asm.

	* configure.ac: Use assembler file sha1-compress.asm if available.

	* x86/sha1-compress.asm (EXPAND): Fixed the rotation part of the
	data expansion.

2004-02-06  Niels Mller  <nisse@lysator.liu.se>

	(BENCH_INTERVAL): Decreased to 0.25s.

	* examples/nettle-benchmark.c (time_function): Loop around calling
	f, until 1s has elapsed. Returns seconds per call. Updated bench
	functions to not loop themselves.
	(display): Updated MB/s calculation.

	* testsuite/arcfour-test.c (test_main): Use test_cipher_stream.

	* 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.

	distributed. 
	(DISTCLEANFILES): And that the symlinks and .s files are deleted.

	* x86/aes-encrypt.asm, x86/aes-decrypt.asm, x86/arcfour-crypt.asm:
	Fixed debug information.

	* x86/arcfour-crypt.asm: New file. About three times faster than
	the optimized C code.

	* configure.ac: Use assembler file arcfour-crypt.asm if available.

	* arcfour.c (arcfour_crypt): Moved function too...
	* arcfour-crypt.c (arcfour_crypt): New file.

	* arcfour.c (arcfour_crypt): Optimization suggested by Jonas
	Walldn. Makes arcfour up to 50% faster on x86 and ppc, and
	probably on other architectures as well.

2004-01-31  Niels Mller  <nisse@lysator.liu.se>

	* configure.ac (AX_CREATE_STDINT_H): Also look for uint32_t and
	friends in sys/types.h.

	* examples/rsa-encrypt-test: New testcase.

	* examples/rsa-encrypt.c, examples/rsa-session.h: Expanded the
	comment describing the file format, and moved to rsa-session.h.

	* examples/rsa-decrypt.c (process_file): Finished this function.
	(main): Initialize x. Check the size of the session key after rsa
	decryption. 

	* examples/io.c (write_string): Treat short item count as an error.

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

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.

	* examples/Makefile.am (EXTRA_DIST): Added rsa-session.h.

	Simon Josefsson.

	* des.c (DesSmallFipsEncrypt, DesSmallFipsDecrypt): Moved
	definitions after the definition of the des_kemap array. 
	
2003-08-11  Niels Mller  <nisse@cuckoo.hack.org>

	(sexp_vformat): Implemented support for literals in the format
	string. 

2003-02-06  Niels Mller  <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 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>

	and output.

2003-01-30  Niels Mller  <niels@s3.kth.se>

	* sexp2bignum.c (nettle_mpz_set_sexp): Call sexp_iterator_next on
