Hash Lookup (Rainbow Table) Educational Only
Dictionary size:
143887
Hashes are ONE-WAY functions — they cannot be mathematically reversed.
This tool only demonstrates a rainbow / dictionary lookup: it checks the hash against a precomputed table of 143887 common passwords, names, words, and hybrid mutations. If found, it means the input was a weak/common choice.

Quick Educational Primer
- MD5 / SHA-256 / SHA-512 are deterministic & one-way. Same input → same hash, always. No "inverse formula" exists.
- Rainbow tables work by precomputing billions of candidate→hash pairs, then looking matches up — essentially a giant space/time tradeoff.
- Why salt defeats rainbow tables: a unique per-user salt is prepended/appended before hashing, so the precomputed tables are useless.
- Rule of thumb for real apps: never store plain passwords. Never use raw SHA/MD5 for passwords. Use salted key-stretching (Argon2id, bcrypt, PBKDF2).
