Контракт

• 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
