Hash of the message

WebA hash is a checksum designed so that no one can forge a message in a way that will result in the same hash as a legitimate message. The output from the message digest algorithm (MD5) or the Secure Hash Algorithm (SHA) hash provides input for an asymmetric key algorithm that uses a private key as input. Hashes are usually of a known fixed size … WebMar 11, 2024 · Alice would write a message, and then create a hash of that message by using the selected algorithm. They would then follow one of the following methods: Alice sends the plaintext message and the hashed message (digital signature) to Bob. Bob receives and hashes the message and compares his hash value to the hash value that …
