이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다.
통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다.

컨트랙트
- assert bcryptjs package manifest confirms resolved version 3.0.3
- assert async bcrypt operations do not execute in the microtask phase, allowing queued process.nextTick microtasks to drain first
- assert fallback dispatcher in environments without setImmediate uses macrotasks (setTimeout / scheduler.postTask) rather than process.nextTick, preventing event loop starvation during async hashing
- assert async functions return a Promise when callback is omitted, but return undefined when a callback function is passed
- assert synchronous methods (hashSync, compareSync) throw Errors immediately on illegal arguments while asynchronous methods (hash, compare) return rejected Promises
- assert compare returns false rather than throwing when encountering a malformed or short hash string
- assert progressCallback tracks computation progress from 0.0 to 1.0 during async hashing and comparison
- assert genSalt shifts arguments when callback is passed as the second argument, and ignores legacy numeric seed_length preserving 16-byte salt length
- assert getSalt extracts the 29-character salt prefix from a 60-character hash and throws Illegal hash length on a raw 29-character salt string
- assert default generated salt revision is $2b$ in v3 while maintaining backward compatibility with legacy $2a$ vectors, and rejecting invalid revisions ($2x$, $1$)
- assert truncates() measures UTF-8 byte length against the 72-byte limit rather than character count, truncating 25 3-byte unicode characters (75 bytes) while keeping 24 characters (72 bytes)
- assert passwords exceeding 72 UTF-8 bytes produce identical hashes to their 72-byte prefix, creating cross-verification collisions
