What is a hash generator?

A hash generator computes fixed-length cryptographic digests (like MD5, SHA256) from text or files. Hashes are commonly used for integrity checks and secure storage.

Can I use this to verify file downloads?

Yes. Upload the file and compare the computed hash with the expected checksum provided by the source to confirm integrity.

Does this tool store my data?

No. All hashing is done locally in your browser for privacy. Files and text never leave your device.

Does it support HMAC?

Yes. You can provide a secret key to generate HMACs using supported hash algorithms like SHA256 and SHA512.
