About Hash Generator
Compute cryptographic hashes (SHA-1, SHA-256, SHA-384, SHA-512) from any text, directly in the browser.
How to use Hash Generator
- 1Enter the text you want to hash in the input field.
- 2Click "Generate" — all four algorithms are computed simultaneously.
- 3Copy the desired hash by clicking the icon next to each result.
- 4Starter+: enable HMAC mode to sign the text with a secret key (message authentication).
Tips
- SHA-256 is the current standard for integrity verification and digital signatures.
- HMAC mode is useful for verifying that a message has not been tampered with — the secret key must be known by both parties.
- An identical hash for two different texts indicates a collision (extremely rare with SHA-256+).
