What does Hash Calculator do?

Hashes verify that a file or piece of text hasn't changed. This calculator produces SHA-1, SHA-256, SHA-384, and SHA-512 fingerprints for text and files.

Hashing runs locally using the browser's SubtleCrypto API, so your input is never uploaded.

Compute SHA-1, SHA-256, SHA-384, and SHA-512 hashes.
Verify text and file integrity with a fingerprint.
Hash locally without uploading anything.

Common use cases

Verifying a downloaded file
Comparing file fingerprints
Generating a checksum for text
