	variable.

2017-11-08  Niels Möller  <nisse@lysator.liu.se>

	* ecc-curve.h (nettle_secp_192r1, nettle_secp_224r1)
	(nettle_secp_256r1, nettle_secp_384r1, nettle_secp_521r1): Delete
	macro wrappers, partially reverting below 2017-04-09 change. They
	didn't work at all for applications that only see a forward
	declaration of struct ecc_curve. Instead, we will have to make an
	ABI and API break and delete these symbols, when the size of
	struct ecc_curve is increased.

2017-11-05  Niels Möller  <nisse@lysator.liu.se>

	* configure.ac Bump package version to 3.4.
	(LIBNETTLE_MINOR): Bump library version to 6.4.
	(LIBHOGWEED_MINOR): Bump library version to 4.4.

2017-10-23  Niels Möller  <nisse@lysator.liu.se>

2017-04-09  Niels Möller  <nisse@lysator.liu.se>

	* ecc-curve.h (nettle_get_secp_192r1, nettle_get_secp_224r1)

	* testsuite/meta-hash-test.c (test_main): Use nettle_lookup_hash.

	* nettle-meta.h (nettle_hashes): New macro, expanding to a call to
	nettle_get_hashes. Direct access to the array causes the array
	size to leak into the ABI, since a plain un-relocatable executable
	linking with libnettle.so gets copy relocations for any referenced
	data items in the shared library.

	* nettle-meta-hashes.c (nettle_get_hashes): New function.

2017-10-16  Niels Möller  <nisse@lysator.liu.se>

	Likewise.
	* nettle-types.h (nettle_armor_encode_update_func)
	(nettle_armor_encode_final_func, nettle_armor_decode_update_func):
	Corresponding updates to typedefs.

2017-09-14  Niels Möller  <nisse@lysator.liu.se>

2017-09-12  Niels Möller  <nisse@lysator.liu.se>

	* testsuite/testutils.h (mpn_zero_p): Avoid redefining mpn_zero_p
	when building with mini-gmp. Since the mini-gmp update, this
	function is defined by mini-gmp, causing link errors if nettle is
	configured with --enable-mini-gmp --disable-shared. Reported by
	Tim Rühsen.

2017-09-09  Daiki Ueno  <dueno@redhat.com>

	* testsuite/ecc-mul-g-test.c (test_main): Fixed mpn_cmp call.
	* testsuite/ecc-mul-a-test.c (test_main): Likewise.
	* eccdata.c (ecc_point_out): Write to given stream, instead of
	stderr.
	* eccdata.c (output_curve): In curve448, the bit size of the order

2017-08-26  Niels Möller  <nisse@lysator.liu.se>

	* examples/nettle-openssl.c (struct openssl_cipher_ctx): New
	struct. Use everywhere, instead of typing EVP_CIPHER_CTX pointers
	directly.

	* configure.ac: Update openssl-related tests. Checks for
	cipher-specific headers are replaced by a check for openssl/evp.h,
	and the check for the BF_ecb_encrypt function is replaced by a
	check for EVP_CIPHER_CTX_new.

2017-08-03  Daniel P. Berrange  <berrange@redhat.com>

	* examples/nettle-openssl.c: Rewritten to use openssl's EVP APIs.
	The older cipher-specific functions always use openssl's generic
	software implementation, while the EVP functions enables
	platform-specific code, e.g., using the x86 AES-NI instructions.
	(nettle_openssl_init): New function.

2017-07-18  Niels Möller  <nisse@lysator.liu.se>

	* ecc-add-eh.c (ecc_add_eh): Fix in-place operation by reordering
	two multiplies. Previously, in-place operation resulted in an
	invalid call to mpn_mul with overlapping operands. Reported by
	Sergei Trofimovich.

2017-06-09  Niels Möller  <nisse@lysator.liu.se>

	* pss.c (pss_verify_mgf1): Check for m being too large, fixing an
	assertion failure for certain invalid signatures. Based on a patch
	contributed by Daiki Ueno.

	* testsuite/rsa-pss-sign-tr-test.c (test_main): Add test case
	contributed by Daiki Ueno. Problem originally found by oss-fuzz,
	see https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2132.
	That problem report is currently embargoed, but will hopefully be
	public in a month or two.

2017-05-23  Niels Möller  <nisse@lysator.liu.se>

	Rework the previous change, which had the unintended effect of
	always regenerating .test-rules.make after ./configure is run.
	* testsuite/Makefile.in (test-rules.stamp): New stamp file target,
	depend on Makefile.in, and run $(MAKE) test-rules.

	on success.

	* testsuite/pss-test.c: Delete magic to let valgrind to check if
	pss_encode_mgf1 is side-channel silent with respect to the salt
	and digest inputs. It turns out that the most significant bits of
	the padded bignum, and hence its size, depends on these inputs.
	Which results in a data-dependent branch in the normalization code
	of at the end of gmp's mpz_import.

2017-04-04  Niels Möller  <nisse@lysator.liu.se>

	* pss.c (pss_verify_mgf1): Use const for input mpz_t argument.

	invalid key doesn't result in a crash inside mpz_powm_sec.

	* rsa-sign-tr.c (rsa_compute_root_tr): Return failure if any of p,
	q or n is even, to avoid crashing inside mpz_powm_sec. Invalid
	keys with even modulo are rejected by rsa_public_key_prepare and

	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 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

	(_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

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

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

	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

	* 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.

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

	* cbc.c (cbc_decrypt_internal): New function, doing the real CBC
