Hash Generator
Generate hashes locally using reviewed algorithms. No logging, no tracking, no telemetry.
Data never leaves your browser. Hashing uses WebCrypto plus same-origin local WASM.
Profiles control the everyday outputs below. Advanced mode exposes additional reviewed algorithms.
Entropy is estimated from length and character set. Higher is better; 100+ bits is excellent.
Time to guess input
Local estimates based on input entropy and target volume.
Larger target sets reduce expected time because an attacker can succeed against any one target.
| Attack mode | Speed | Estimated time |
|---|---|---|
| Offline (GPU) | ~ 10^12 guesses/sec | N/A |
| Offline (CPU) | ~ 10^8 guesses/sec | N/A |
| Online | ~ 100 guesses/hour | N/A |
Advanced mode
Enable additional reviewed algorithms, including rare SHA-3, BLAKE, regional, legacy, and checksum families.
