How the result is calculated
The pinned bcrypt.js implementation obtains a fresh random salt from Web Crypto and produces a 60-character $2b$ hash. Identical passwords normally produce different hashes because each generation uses a new salt.
Read the current bcrypt.js browser implementation and security notes before submitting.
All calculation and transformation work happens in this browser tab. No entered value is sent to an Noler Tools application server.
Important limitations
Results are provided for convenience and should be checked independently before an important decision. A format or checksum result never authenticates an identity, document, account, licence, vehicle or registration.
