diff --git a/CHANGELOG.md b/CHANGELOG.md deleted file mode 100644 index dacb0a3f4..000000000 --- a/CHANGELOG.md +++ /dev/null @@ -1,105 +0,0 @@ -# Changelog - -All notable changes to this project will be documented in this file. - -The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), -and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). - -## [Unreleased] - -#### 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](https://eprint.iacr.org/2022/759) on which the scheme is based. - -#### Changed - - When consuming libsecp256k1 as a static library on Windows, the user must now define the `SECP256K1_STATIC` macro before including `secp256k1.h`. - -## [0.3.2] - 2023-05-13 -We strongly recommend updating to 0.3.2 if you use or plan to use GCC >=13 to compile libsecp256k1. When in doubt, check the GCC version using `gcc -v`. - -#### Security - - Module `ecdh`: Fix "constant-timeness" issue with GCC 13.1 (and potentially future versions of GCC) that could leave applications using libsecp256k1's ECDH module vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow during ECDH computations when libsecp256k1 is compiled with GCC 13.1. - -#### Fixed - - Fixed an old bug that permitted compilers to potentially output bad assembly code on x86_64. In theory, it could lead to a crash or a read of unrelated memory, but this has never been observed on any compilers so far. - -#### Changed - - Various improvements and changes to CMake builds. CMake builds remain experimental. - - Made API versioning consistent with GNU Autotools builds. - - Switched to `BUILD_SHARED_LIBS` variable for controlling whether to build a static or a shared library. - - Added `SECP256K1_INSTALL` variable for the controlling whether to install the build artefacts. - - Renamed asm build option `arm` to `arm32`. Use `--with-asm=arm32` instead of `--with-asm=arm` (GNU Autotools), and `-DSECP256K1_ASM=arm32` instead of `-DSECP256K1_ASM=arm` (CMake). - -#### ABI Compatibility -The ABI is compatible with versions 0.3.0 and 0.3.1. - -## [0.3.1] - 2023-04-10 -We strongly recommend updating to 0.3.1 if you use or plan to use Clang >=14 to compile libsecp256k1, e.g., Xcode >=14 on macOS has Clang >=14. When in doubt, check the Clang version using `clang -v`. - -#### Security - - Fix "constant-timeness" issue with Clang >=14 that could leave applications using libsecp256k1 vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow and secret-dependent memory accesses in conditional moves of memory objects when libsecp256k1 is compiled with Clang >=14. - -#### Added - - Added tests against [Project Wycheproof's](https://github.com/google/wycheproof/) set of ECDSA test vectors (Bitcoin "low-S" variant), a fixed set of test cases designed to trigger various edge cases. - -#### Changed - - Increased minimum required CMake version to 3.13. CMake builds remain experimental. - -#### ABI Compatibility -The ABI is compatible with version 0.3.0. - -## [0.3.0] - 2023-03-08 - -#### Added - - Added experimental support for CMake builds. Traditional GNU Autotools builds (`./configure` and `make`) remain fully supported. - - Usage examples: Added a recommended method for securely clearing sensitive data, e.g., secret keys, from memory. - - Tests: Added a new test binary `noverify_tests`. This binary runs the tests without some additional checks present in the ordinary `tests` binary and is thereby closer to production binaries. The `noverify_tests` binary is automatically run as part of the `make check` target. - -#### Fixed - - Fixed declarations of API variables for MSVC (`__declspec(dllimport)`). This fixes MSVC builds of programs which link against a libsecp256k1 DLL dynamically and use API variables (and not only API functions). Unfortunately, the MSVC linker now will emit warning `LNK4217` when trying to link against libsecp256k1 statically. Pass `/ignore:4217` to the linker to suppress this warning. - -#### Changed - - Forbade cloning or destroying `secp256k1_context_static`. Create a new context instead of cloning the static context. (If this change breaks your code, your code is probably wrong.) - - Forbade randomizing (copies of) `secp256k1_context_static`. Randomizing a copy of `secp256k1_context_static` did not have any effect and did not provide defense-in-depth protection against side-channel attacks. Create a new context if you want to benefit from randomization. - -#### Removed - - Removed the configuration header `src/libsecp256k1-config.h`. We recommend passing flags to `./configure` or `cmake` to set configuration options (see `./configure --help` or `cmake -LH`). If you cannot or do not want to use one of the supported build systems, pass configuration flags such as `-DSECP256K1_ENABLE_MODULE_SCHNORRSIG` manually to the compiler (see the file `configure.ac` for supported flags). - -#### ABI Compatibility -Due to changes in the API regarding `secp256k1_context_static` described above, the ABI is *not* compatible with previous versions. - -## [0.2.0] - 2022-12-12 - -#### Added - - Added usage examples for common use cases in a new `examples/` directory. - - Added `secp256k1_selftest`, to be used in conjunction with `secp256k1_context_static`. - - Added support for 128-bit wide multiplication on MSVC for x86_64 and arm64, giving roughly a 20% speedup on those platforms. - -#### Changed - - Enabled modules `schnorrsig`, `extrakeys` and `ecdh` by default in `./configure`. - - The `secp256k1_nonce_function_rfc6979` nonce function, used by default by `secp256k1_ecdsa_sign`, now reduces the message hash modulo the group order to match the specification. This only affects improper use of ECDSA signing API. - -#### Deprecated - - Deprecated context flags `SECP256K1_CONTEXT_VERIFY` and `SECP256K1_CONTEXT_SIGN`. Use `SECP256K1_CONTEXT_NONE` instead. - - Renamed `secp256k1_context_no_precomp` to `secp256k1_context_static`. - - Module `schnorrsig`: renamed `secp256k1_schnorrsig_sign` to `secp256k1_schnorrsig_sign32`. - -#### ABI Compatibility -Since this is the first release, we do not compare application binary interfaces. -However, there are earlier unreleased versions of libsecp256k1 that are *not* ABI compatible with this version. - -## [0.1.0] - 2013-03-05 to 2021-12-25 - -This version was in fact never released. -The number was given by the build system since the introduction of autotools in Jan 2014 (ea0fe5a5bf0c04f9cc955b2966b614f5f378c6f6). -Therefore, this version number does not uniquely identify a set of source files. - -[unreleased]: https://github.com/bitcoin-core/secp256k1/compare/v0.3.2...HEAD -[0.3.2]: https://github.com/bitcoin-core/secp256k1/compare/v0.3.1...v0.3.2 -[0.3.1]: https://github.com/bitcoin-core/secp256k1/compare/v0.3.0...v0.3.1 -[0.3.0]: https://github.com/bitcoin-core/secp256k1/compare/v0.2.0...v0.3.0 -[0.2.0]: https://github.com/bitcoin-core/secp256k1/compare/423b6d19d373f1224fd671a982584d7e7900bc93..v0.2.0 -[0.1.0]: https://github.com/bitcoin-core/secp256k1/commit/423b6d19d373f1224fd671a982584d7e7900bc93 diff --git a/CMakeLists.txt b/CMakeLists.txt deleted file mode 100644 index 3107eb3bf..000000000 --- a/CMakeLists.txt +++ /dev/null @@ -1,341 +0,0 @@ -cmake_minimum_required(VERSION 3.13) - -if(CMAKE_VERSION VERSION_GREATER_EQUAL 3.15) - # MSVC runtime library flags are selected by the CMAKE_MSVC_RUNTIME_LIBRARY abstraction. - cmake_policy(SET CMP0091 NEW) - # MSVC warning flags are not in CMAKE__FLAGS by default. - cmake_policy(SET CMP0092 NEW) -endif() - -project(libsecp256k1 - # The package (a.k.a. release) version is based on semantic versioning 2.0.0 of - # the API.

- - - -## 關於該項目 - -![Product Name Screen Shot](https://github.com/BitgesellOfficial/bitgesell/blob/master/share/pixmaps/BGL64.png) - -BGL 是一種實驗性數字貨幣，可以向世界上任何地方的任何人即時付款。BGL 使用點對點技術在沒有中央權限的情況下運行：管理交易和發行貨幣由網絡共同執行。 BGL Core 是允許使用這種貨幣的開源軟件的名稱。 - -Bitgesell 是比特幣的一個分支，有以下變化：
-* 區塊獎勵 [燃燒率是交易費用的 90%] - ```sh - nFees*0.1 + GetBlockSubsidy() - ``` -* 區塊重量 [比比特幣小 10 倍] - ```sh - <= 400,000 - ``` -* 100% Segwit - ```sh - 消除遺留類型交易的問題 - ``` -* 減半間隔 [bitgetsell 的減半週期為 1 年，而比特幣的減半週期為 4 年] - ```sh - 210000 blocks/4 - ``` -* 區塊補貼 [最大硬幣 = 21,000,000]
- `210000 blocks/4`
- `塊的哈希算法是 Keccak (sha-3).`
- `master 分支定期搭建 (看` [doc/build-*.md](https://github.com/BitgesellOfficial/bitgesell/tree/master/doc) `說明) 並經過測試，但不保證完全穩定。`
- [標籤](https://github.com/BitgesellOfficial/bitgesell/tags) `定期創建，以指示 BGL Core 的新官方穩定發行版本。`
- - -### 內置 - -* [C++](#) -* [C](#) -* [Python](#) -* [SourcePawn](#) -* [M4](#) -* [Shell](#) - - - -## 入門 - -[GUI](https://github.com/BGL-core/gui) 存儲庫專門用於 GUI 的開發。它的 master 分支在所有 monotree 存儲庫中都是相同的。發布分支和標籤不存在，所以除非出於開發原因，否則請不要分叉該存儲庫。 - -官方線程: [點擊這裡](https://bitcointalk.org/index.php?topic=5238559.0) - - -### 自動化測試 - -強烈鼓勵開發人員為新代碼編寫 [單元測試](https://github.com/BitgesellOfficial/bitgesell/blob/master/src/test/README.md)，並 -為舊代碼提交新的單元測試。可以編譯和運行單元測試 -（假設它們在配置中沒有被禁用）：`make check`。關於跑步的更多細節 -擴展單元測試可以在 [src/test/README.md](https://github.com/BitgesellOfficial/bitgesell/blob/master/src/test/README.md) 中找到。
- -還有 [回歸和集成測試](https://github.com/BitgesellOfficial/bitgesell/tree/master/test)，寫的 -在 Python 中。
-這些測試可以運行 [如果[測試依賴項](https://github.com/BitgesellOfficial/bitgesell/tree/master/test) 與: `test/functional/test_runner.py`
- -CI（持續集成）系統確保每個拉取請求都是為 Windows、Linux 和 macOS 構建的， -並且自動運行單元/健全性測試.
- - -### 手動質量保證 (QA) 測試 - -更改應由編寫該更改的開發人員以外的其他人進行測試 -代碼。這對於大的或高風險的變化尤其重要。它是有益的 -如果測試更改，則將測試計劃添加到拉取請求描述中 -不直截了當。 - - - -## 路線圖 - -請參閱 [open issues](https://github.com/BitgesellOfficial/bitgesell/issues) 以獲取建議功能（和已知問題）的列表。 - - - -## 貢獻 - -貢獻使開源社區成為學習、啟發和創造的絕佳場所。 **非常感謝您做出的任何貢獻**。 - -1. 分叉項目 -2. 創建你的功能分支 -3. 提交您的更改 -4.推送到分行 -5.打開拉取請求 - - - - -## 執照 - -在 MIT 許可下分發。有關更多信息，請參閱 [許可證](https://github.com/BitgesellOfficial/bitgesell/blob/master/COPYING)。 - - - - -## 接觸 - -Discord - [Bitgesell](https://discord.com/invite/Ubp359vZEF) - -Twitter: [Bitgesell](https://twitter.com/Bitgesell) - -Medium: [Bitgesell](https://bitgesell.medium.com/) - -Facebook: [Bitgesell](https://www.facebook.com/Bitgesell) - - - -## 翻譯 - -可以提交對翻譯的更改以及新的翻譯 -[BGL Core 的 Transifex 頁面](https://www.transifex.com/bitcoin/bitcoin/)。 - -翻譯會定期從 Transifex 中提取並合併到 git 存儲庫中。見 -[翻譯過程](doc/translation_process.md) 了解有關其工作原理的詳細信息。 - -**重要**：我們不接受作為 GitHub 拉取請求的翻譯更改，因為下一個 -從 Transifex 拉取會自動再次覆蓋它們。 -
