Hash Builder
Choose an algorithm and generate the output.
Generate, verify, and inspect hashes in the browser.
Choose an algorithm and generate the output.
Copy the result or check the metadata.
Hashes are one-way outputs, not reversible encryption.
Supported groups at a glance.
Focused on browser-safe algorithms.
Paste a hash and test a candidate value.
bcrypt and Argon2 work best because their encoded strings include the parameters needed for verification.
Quick pattern-based guessing.
The inspector uses prefixes, encoding style, and digest length to narrow down likely algorithms. It gives practical guesses, not guarantees.
Use for verification, migration, debugging, or compatibility checks.
