| Version: 0.5.1 | Vendor: openSUSE |

| Group: System/Libraries | Build host: reproducible |
| Size: 1272254 | Source RPM: libsecp256k1-0.5.1-1.1.src.rpm |

| Summary: Optimized C library for EC operations on curve secp256k1 | |
The libsecp256k1 library is a work in progress and is being used to research best practices. Use at your own risk. Features: - secp256k1 ECDSA signing/verification and key generation. - Adding/multiplying private/public keys. - Serialization/parsing of private keys, public keys, signatures. - Constant time, constant memory access signing and pubkey generation. - Derandomized DSA (via RFC6979 or with a caller provided function.) - Very efficient implementation.

* Fri Aug 02 2024 Michael Vetter <mvetter@suse.com>
- Update to 0.5.1:
* Added usage example for an ElligatorSwift key exchange.
* The default size of the precomputed table for signing was changed
from 22 KiB to 86 KiB. The size can be changed with the configure
option --ecmult-gen-kb (SECP256K1_ECMULT_GEN_KB for CMake).
* "auto" is no longer an accepted value for the --with-ecmult-window
and --with-ecmult-gen-kb configure options (this also applies to
SECP256K1_ECMULT_WINDOW_SIZE and SECP256K1_ECMULT_GEN_KB in CMake).
To achieve the same configuration as previously provided by the
"auto" value, omit setting the configure option explicitly.
* Fixed compilation when the extrakeys module is disabled.
* The ABI is backward compatible with versions 0.5.0, 0.4.x and 0.3.x.

- Update to 0.5.0:
Added:
* New function secp256k1_ec_pubkey_sort that sorts public keys
using lexicographic (of compressed serialization) order.
Changed:
* The implementation of the point multiplication algorithm used
for signing and public key generation was changed, resulting
in improved performance for those operations. The related
configure option --ecmult-gen-precision was replaced with
- -ecmult-gen-kb (ECMULT_GEN_KB for CMake).
This changes the supported precomputed table sizes for these
operations. The new supported sizes are 2 KiB, 22 KiB, or 86
KiB (while the old supported sizes were 32 KiB, 64 KiB, or 512 KiB).
ABI Compatibility:
* The ABI is backward compatible with versions 0.4.x and 0.3.x.
* Fri Dec 22 2023 Michael Vetter <mvetter@suse.com>
- Update to 0.4.1:
* The point multiplication algorithm used for ECDH operations
(module ecdh) was replaced with a slightly faster one.
* Optional handwritten x86_64 assembly for field operations was
removed because modern C compilers are able to output more efficient
assembly. This change results in a significant speedup of some
library functions when handwritten x86_64 assembly is enabled
(--with-asm=x86_64 in GNU Autotools, -DSECP256K1_ASM=x86_64 in CMake),
which is the default on x86_64. Benchmarks with GCC 10.5.0 show a
10% speedup for secp256k1_ecdsa_verify and secp256k1_schnorrsig_verify.

- Update to 0.4.0:
Added:
* New module ellswift implements ElligatorSwift encoding for public
keys and x-only Diffie-Hellman key exchange for them. ElligatorSwift
permits representing secp256k1 public keys as 64-byte arrays which
cannot be distinguished from uniformly random. See:
+ Header file include/secp256k1_ellswift.h which defines the new API.
+ Document doc/ellswift.md which explains the mathematical background
of the scheme.
+ The paper on which the scheme is based.
* We now test the library with unreleased development snapshots of GCC
and Clang. This gives us an early chance to catch miscompilations and
constant-time issues introduced by the compiler (such as those that
led to the previous two releases).
Fixed:
* Fixed symbol visibility in Windows DLL builds, where three internal
library symbols were wrongly exported.
Changed:
* When consuming libsecp256k1 as a static library on Windows, the user
must now define the SECP256K1_STATIC macro before including secp256k1.h.
ABI Compatibility:
* This release is backward compatible with the ABI of 0.3.0, 0.3.1,
and 0.3.2. Symbol visibility is now believed to be handled properly
on supported platforms and is now considered to be part of the ABI.
