Hash function for signature file index

WebJul 5, 2024 · Unlike checksums or hashes, a signature involves a secret. This is important, because while the hash for a file can be calculated by anyone, a signature can only be calculated by someone who has the secret. Signatures use asymmetric cryptography, so there is a public key and a private key. WebFeb 14, 2024 · Signature: The encrypted hash is the document's digital signature. Verification: The signature is then verified using the sender's public key to ensure the signature's validity and the document's authenticity.
