一个纯 Dart 编写的安全哈希函数、校验和、MAC、密钥派生函数、OTP 生成器和安全随机数的库——这是一个广泛、快速且依赖轻量级的工具箱，可以在 Dart 运行的任何地方运行。
`hashlib` 是一个由三个包组成的家族中的中间层：
[](https://pub.dev/packages/convertlib) → [](https://pub.dev/packages/hashlib) → [](https://pub.dev/packages/cipherlib)
它基于 `convertlib` 进行十六进制、Base32/Base64 和 UTF-8 转换，这也是它唯一的运行时依赖。
## 核心亮点
- **支持所有平台**：纯 Dart 实现，无需原生代码或 FFI，因此同一套库可以在 Dart 运行的任何地方工作——包括 VM、Flutter（Android、iOS、Windows、macOS、Linux）以及 Web（dart2js 和 dart2wasm）。
- **功能齐全**：包含十多个哈希家族（MD、SHA-1、SHA-2、SHA-3、SHAKE、Keccak、BLAKE2、RIPEMD、SM3、xxHash）、校验和（CRC、Adler-32）、MAC（HMAC、Poly1305）、密码 KDF（Argon2、scrypt、bcrypt、PBKDF2）、TOTP/HOTP 以及 RNG/UUID 生成器。
- **单次或流式处理**：可以在单次调用中对 `String` 或字节缓冲区进行哈希处理，或者对于大文件或分块输入，通过可重用的 sink 增量式地喂入数据。
- **密码级别的 KDF**：支持 Argon2id、scrypt、bcrypt 和 PBKDF2，通过具名的 `security` 预设使成本/延迟权衡更加明确。
- **极速**：在性能上持续超越 `crypto`、`PointyCastle` 和 `hash`，详情请参阅下方的[基准测试](#benchmarks)。
- **内置编解码器和安全随机数**：随包附带了配套的 `codecs` 和 `random` 库。
## 安装
```
dependencies:
hashlib: ^2.4.1
```
或者运行 `dart pub add hashlib`。只需一个 import 即可暴露所有的算法：
```
import 'package:hashlib/hashlib.dart';
```
两个配套库与其完美搭配——`codecs` 用于十六进制/Base/UTF-8 转换（从 `convertlib` 重新导出），`random` 用于生成安全的随机字节、数字和 UUID：
```
import 'package:hashlib/codecs.dart'; // toHex, fromHex, toBase64, toUtf8
import 'package:hashlib/random.dart'; // randomBytes, uuid, HashlibRandom
```
完整的 API 参考：[hashlib 库](https://pub.dev/documentation/hashlib/latest/)。
## 快速入门
通过单次调用计算字符串的摘要，并通过附加密钥从任意哈希派生出 HMAC：
```
import 'package:hashlib/hashlib.dart';
void main() {
final text = 'Happy Hashing!';
// One-shot hex digest
print(sha256.string(text));
// Keyed HMAC-SHA256
print(sha256.hmac.byString('password').string(text));
}
```

### 随机数与 UUID
`random` 库通过 `HashlibRandom`（`secure`, `system`, `keccak`, `sha256`, `md5`, `xxh64`, `sm3`）提供随机数生成器，以及像 `randomBytes`、`randomNumbers` 和 `randomString` 这样的辅助工具。UUID 的 v1、v3、v4、v5、v6、v7 和 v8 版本可以通过 `uuid` 获取。
## 安全说明
- **使用 KDF 而不是裸哈希来处理密码。** 存储带有适当 `security` 预设的 `argon2id`（或 `scrypt` / `bcrypt`）输出——绝不是密码的普通 `sha256`——并使用 `argon2Verify` / `bcryptVerify` 进行检查。
- **在恒定时间内比较摘要。** 在验证 MAC 和摘要时，使用 `HashDigest.isEqual` 代替 `==` 或手动字节循环，以避免通过时间差泄露信息。
- **旧算法仅供兼容使用。** MD2、MD4、MD5 和 SHA-1 已在密码学上被破解；仅将它们用于互操作性或非安全性校验和，对于新项目，请优先选择 SHA-256、SHA-3 或 BLAKE2。
- **非密码学哈希。** CRC、Adler-32 和 xxHash 系列是用于快速完整性和查找的哈希，面对对手时并不安全——不要在需要抗冲突或抗原像的场景中使用它们。
- **运行时计时。** 纯 Dart 执行（JIT、AOT、dart2js）不保证在恒定时间内运行；在依赖它处理侧信道敏感的环境之前，请仔细权衡部署环境。
## 测试与可靠性
正确性是本库的首要目标，测试套件正是为了执行这一目标而构建的。这里有 **分布在 60 多个文件中的 700 个测试用例**，在每次更改后和每次发布前，都会在 **三个平台上运行：Dart VM、Node.js 和 Chrome (WASM)**。
每个算法都通过几种独立的方式进行验证：
- **官方已知答案测试向量。** 摘要会根据相关标准——RFC、FIPS/NIST 出版物以及每种算法的参考实现——发布的测试向量进行固定比对。预期值绝不是凭空捏造的；每个向量都在测试文件中注明了其来源。
- **差异化交叉验证。** 对于其他成熟的、独立的 Dart 包也实现了的每种算法，其输出都会与 [`crypto`][crypto] 和 [`pointycastle`][pointycastle] 在数百个随机输入上进行逐字节比对。目前这涵盖了 MD2、MD4、MD5、SHA-1、SHA-224/256/384/512、SHA-512/224、SHA-512/256、SHA3（224–512）、Keccak（224–512）、RIPEMD-128/160/256/320、BLAKE2b、SM3 和 HMAC。填充、字节序或块边界上的细微差异都可能导致这些测试失败，即使它逃脱了固定向量的检查。
- **边界与边缘覆盖。** 输入会在空字符串、单字节以及跨越每个算法内部块/速率大小的长度（例如 `block−1`、`block`、`block+1` 和多块消息）上进行测试——这正是隐藏长度编码和填充错误的地方。
- **流式等同于单次处理。** 分块/流式输入和增量 `Sink` API（包括 `reset()`、双重 `close()` 和关闭后使用）经验证会产生与单次处理路径完全相同的摘要。
- **参数验证。** 断言无效的密钥、盐值、摘要和参数长度会抛出类型化错误，而不是默默产生弱输出。
这些算法计算出的正是其标准所定义的结果，
并已通过官方向量和多个独立实现进行了验证。
仍然请您阅读上方的[安全说明](#security-notes)：
为你的威胁模型选择正确的原语（KDF 用于密码，在涉及对手时使用密码学哈希而不是校验和），并请注意纯 Dart 执行并不提供严格的恒定时间保证。
你可以在本地复现所有这一切：
```
dart test # vm, node, and chrome
dart test -p vm # fast, VM-only iteration
```
