本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Enforce package:crypto internal invariant assertions and runtime behavior under Dart's --enable-asserts flag
- 符号
-
- HashSink
- Hmac
- Digest
- sha256
- 环境
- dart
- 创建时间
- 2026-08-17T03:18:36Z
契约
- Instantiating HashSink with signatureBytes less than 8 bypasses checks and produces a digest in default mode, but throws AssertionError only when Dart is run with the --enable-asserts flag.
- assert that digest instances compare by value with == while comparing their bytes property checks reference identity
- assert that Hmac key list elements outside 0..255 are truncated to 8-bit integers without throwing an ArgumentError
- assert that chunked conversion sinks emit a Digest to the destination sink only after close() is called
