Choose a file and Generate a Hash (keccak256)
You cannot store files directly in our database. Instead, you can save a file's URL and the hash of the file (use only public files). This approach allows you to retrieve the file using the URL and verify its integrity by comparing its hash with the one stored in our database. If the hashes match, you can be confident that the file has not been altered.
