Privacy note

Files are read locally with the browser File API. They are not uploaded to a server.

Input

Choose text or a file.

MD5 and SHA-1 are included for compatibility and learning. Use SHA-256 or SHA-512 for modern integrity checks.

Output

Hash results will appear here.

Hashing is one-way. It helps verify integrity and compare data, but it is not encryption and cannot recover the original input.

HMAC Generator — Hash-Based Message Auth

Generate HMAC signatures using SHA-1, SHA-256, or SHA-512 with a secret key.

File Hash Generator — Compute File Checksums

Compute MD5, SHA-1, SHA-256, and SHA-512 checksums for any uploaded file without uploading to a server.
