Frequently asked questions

Is my hash sent to your server?
No. Identification runs entirely in your browser using WebAssembly. Your hash is never uploaded, logged, or stored.
How does the hash identifier work?
It matches your input against a library of hash-type patterns (length, character set, and prefix) and ranks the most likely formats, then shows the hashcat mode and John the Ripper format for each.
Can you crack the hash for me?
No. This site only identifies the hash and gives you the exact hashcat and John the Ripper commands to run yourself on your own machine.
