Common Issues

Error 1

Error 1

If the source text is empty, the tool cannot produce a meaningful verification result.

Error 2

Error 2

HMAC modes require a secret key before the output can be generated.

Frequently Asked Questions

Frequently Asked Questions

Does this tool support HMAC modes?

Yes. HMAC-SHA-256 and HMAC-SHA-512 are available when you need secret-based verification.

Can I compare the output with an existing hash?

Yes. Paste an expected hash value to compare it with the generated result.

Is the hash generated in the browser?

Yes. The hashing logic runs locally in the browser during normal use.
