Web10 de jun. de 2024 · In this question I asked about how to handle situations when SHA-256 hashes are not available for a file downloaded from the internet that contains executable code. Another community member insightfully asked if a hash is really needed to validate the download (in this case, LibreOffice), since it is a digitally signed file. Web10. Digital Signatures, hashes and MACs can do similar jobs. They allow someone sending a message to a check value along with the message. They allow someone receiving the message to verify that the message corresponds to the check value. However, a hash is an unkeyed operation; anyone can compute the hash of the message.
