I would like to ask a user to generate a "Keccak-256" or "Keccak-512" (Ethereum versions of SHA3) of a PDF file. Is there a recommended website with a good GUI to generate that?

The user would input a PDF file and the system will return "Keccak-256" or "Keccak-512" of this file.

Obs.: I know I can program a service to that. It is just a MVP.


You can use this website to create a Keccak256 or Keccack512 checksum of a file:
