What is Bcrypt Verifier?
Bcrypt Verifier takes a bcrypt hash and a candidate password, then reports whether they match plus useful metadata: the variant ($2a, $2b, or $2y), the cost factor (4–14), and whether the hash format is well-formed. Verification runs entirely in your browser via `bcryptjs` — neither the password nor the hash is sent to any server. Use this to debug authentication flows, verify migrated user records, or confirm a password reset. This tool is part of santekno's developer toolbox — a curated collection of utilities built for engineers who care about speed, privacy, and simplicity.
