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。

契约
- assert compareSync returns boolean false for mismatched hashes whose length is not 60, but throws an uncaught Error on 60-character invalid or unsupported revision strings, while async hash rejects with Illegal arguments unless rounds or salt is explicitly supplied
- assert hashSync defaults to 10 rounds producing a 60-character $2b$10$ hash when salt is omitted, whereas async hash without salt rejects with 'Illegal arguments: string, undefined'
- assert setRandomFallback does not override crypto.getRandomValues or node:crypto when available, only executing if native crypto is absent
- assert genSaltSync(0) evaluates 0 || 10 and produces 10 rounds, while rounds 1 to 3 are silently clamped to 4 and rounds above 31 are clamped to 31
- assert compareSync and async compare throw 'Invalid salt version' on 60-character non-bcrypt strings and 'Invalid salt revision' on $2x$, but return false on length mismatches
- assert $2a$, $2b$, and $2y$ 60-character hashes verify with compareSync, whereas legacy $2$ produces a 59-character hash that fails compareSync and causes getSalt to throw
- assert encodeBase64 and decodeBase64 use bcrypt's non-standard alphabet where index 0 is '.' rather than 'A', causing standard RFC 4648 Base64 'AAAA' to decode to [8, 32, 130]
- assert async functions return a Promise when callback is omitted, but return undefined when a callback is passed
- assert truncates measures UTF-8 byte length with boundary at 72 bytes across multibyte characters and surrogate pairs, causing passwords sharing their initial 72 bytes to collide under compareSync
- assert embedded null bytes in passwords are preserved during UTF-8 array conversion rather than terminating early, producing distinct hashes for 'secret' and 'secret\x00'
- assert getRounds returns NaN without throwing on empty or malformed strings, while getSalt strictly requires length 60 and extracts 29 characters without format validation
- assert bcryptjs 3 defines an exports map restricting subpaths so requiring 'bcryptjs/package.json' throws ERR_PACKAGE_PATH_NOT_EXPORTED
