| Summary: Cryptographic Tools | |
Nettle is a cryptographic library that is designed to fit easily in more or less any context: In crypto toolkits for object-oriented languages (C++, Python, Pike, ...), in applications like LSH or GNUPG, or even in kernel space. This package contains a few command-line tools to perform cryptographic operations using the nettle library.
GPL-2.0-or-later AND LGPL-2.1-or-later
* Mon Jun 17 2024 Pedro Monreal <pmonreal@suse.com>
- Update to 3.10:
* Bug fixes:
- Add missing hash functions sha512_224 and sha512_256 to the
nettle_get_hashes() list. The name values in the
corresponding nettle_hash structs also changed to use
underscore instead of dash, for consistency.
- Fix a few cases of formally undefined calls to memcpy(dst,
NULL, 0), resulting from valid calls to, e.g.,
sha256_update(ctx, 0, NULL).
* New features:
- Support RSA-OAEP encryption. Contributed by Nicolas Mora and Daiki Ueno.
- New function sha3_256_shake_output, new functions
sha3_128_init, sha3_128_update, sha3_128_shake,
sha3_128_shake_output. Contributed by Daiki Ueno.
- Added DRBG-CTR with AES256, contributed by Simon Josefsson.
* Optimizations:
- New combined gcm-aes assembly for powerpc64, contributed by Danny Tsen.
- New sha256 assembly for powerpc64, contributed by Eric Richter.
- Improved performance for powerpc64 AES decrypt, by skipping
subkey transformations that don't suit the vncipher instructions.
- Add arm64 CPU feature detection for Android and for Apple systems,
contributed by Foolbar and Tim Kosse, prespectively.
* Miscellaneous:
- New tests for side-channel silence, based on valgrind.
- Delete all md5 assembly code. Delete all sparc32 assembly code.
* Fri Jun 09 2023 Pedro Monreal <pmonreal@suse.com>
- Add the architecture specific READMEs as provided by upstream.
* Thu Jun 08 2023 Pedro Monreal <pmonreal@suse.com>
- Include the nettle library manual in HTML and PDF formats in
the devel package.
* Wed Jun 07 2023 Andreas Stieger <andreas.stieger@gmx.de>
- update to 3.9.1: [bsc#1212112, CVE-2023-36660]
* Fix bug in the new OCB code may be exploitable for denial of
service or worse due to memory corruption
* Mon May 15 2023 Andreas Stieger <andreas.stieger@gmx.de>
- update to 3.9
* rewrite of the C and plain x86_64 assembly implementations of
GHASH to use precomputed tables in a different way, with tables
always accessed in the same sequential manner. This should make
Nettle's GHASH implementation side-channel silent on all
platforms, but considerably slower on platforms without carry-
less mul instructions. E.g., benchmarks of the C implementation
on x86_64 showed a slowdown of 3 times.
* Fix bug in ecdsa and gostdsa signature verify operation, for
the unlikely corner case that point addition really is point
duplication.
* Fix for chacha on Power7, nettle's assembly used an instruction
only available on later processors
* Add support for the SM4 block cipher
* Add support for the Balloon password hash
* Add support for SIV-GCM authenticated encryption mode
* Add support for OCB authenticated encryption mode.
* New exported functions md5_compress, sha1_compress,
sha256_compress, sha512_compress
* multiple performance optimizations
* Delete all arcfour assembly code. Affects 32-bit x86, 32-bit
and 64-bit sparc
* Wed Mar 08 2023 Martin Pluskal <mpluskal@suse.com>
- Build AVX2 enabled hwcaps library for x86_64-v3
* Thu Jul 28 2022 Dirk Müller <dmueller@suse.com>
- update to 3.8.1:
* Avoid non-posix m4 argument references in the chacha
implementation for arm64, powerpc64 and s390x. Reported by
Christian Weisgerber, fix contributed by Mamone Tarsha.
* Use explicit .machine pseudo-ops where needed in s390x
assembly files. Bug report by Andreas K. Huettel, fix
contributed by Mamone Tarsha.
* Mon Jul 11 2022 Dirk Müller <dmueller@suse.com>
- update to 3.8:
This release includes a couple of new features, and many
performance improvements. It adds assembly code for two more
architectures: ARM64 and S390x.
The new version is intended to be fully source and binary
compatible with Nettle-3.6. The shared library names are
libnettle.so.8.5 and libhogweed.so.6.5, with sonames
libnettle.so.8 and libhogweed.so.6.
New features:
* AES keywrap (RFC 3394), contributed by Nicolas Mora.
* SM3 hash function, contributed by Tianjia Zhang.
* New functions cbc_aes128_encrypt, cbc_aes192_encrypt,
cbc_aes256_encrypt.
On processors where AES is fast enough, e.g., x86_64 with
aesni instructions, the overhead of using Nettle's general
cbc_encrypt can be significant. The new functions can be
implemented in assembly, to do multiple blocks with reduced
per-block overhead.
Note that there's no corresponding new decrypt functions,
since the general cbc_decrypt doesn't suffer from the same
performance problem.
Bug fixes:
* Fix fat builds for x86_64 windows, these appear to never
have worked.
Optimizations:
* New ARM64 implementation of AES, GCM, Chacha, SHA1 and
SHA256, for processors supporting crypto extensions. Great
speedups, and fat builds are supported. Contributed by
Mamone Tarsha.
* New s390x implementation of AES, GCM, Chacha, memxor, SHA1,
SHA256, SHA512 and SHA3. Great speedups, and fat builds are
supported. Contributed by Mamone Tarsha.
* New PPC64 assembly for ecc modulo/redc operations,
contributed by Amitay Isaacs, Martin Schwenke and Alastair
D´Silva.
* The x86_64 AES implementation using aesni instructions has
been reorganized with one separate function per key size,
each interleaving the processing of two blocks at a time
(when the caller processes multiple blocks with each call).
This gives a modest performance improvement on some
processors.
* Rewritten and faster x86_64 poly1305 assembly.

- GNU Nettle 3.7.3: [CVE-2021-3580, bsc#1187060]
* Fix crash for zero input to rsa_sec_decrypt and
rsa_decrypt_tr. Potential denial of service vector.
* Ensure that all of rsa_decrypt_tr and rsa_sec_decrypt return
failure for out of range inputs, instead of either crashing,
or silently reducing input modulo n. Potential denial of
service vector.
* Ensure that rsa_decrypt returns failure for out of range
inputs, instead of silently reducing input modulo n.
* Ensure that rsa_sec_decrypt returns failure if the message
size is too large for the given key. Unlike the other bugs,
this would typically be triggered by invalid local
configuration, rather than by processing untrusted remote
data.
* Sun Mar 21 2021 Andreas Stieger <andreas.stieger@gmx.de>
- GNU Nettle 3.7.2:
* fix a bug in ECDSA signature verification that could lead to a
denial of service attack (via an assertion failure) or possibly
incorrect results (CVE-2021-20305, boo#1184401)
* fix a few related problems where scalars are required to be
canonically reduced modulo the ECC group order, but in fact may
be slightly larger
