WebNov 2, 2024 · So, in simple terms we can say that a hash function is used to transform a given key into a specific slot index. Its main job is to map each and every possible key into a unique slot index. If every key is mapped into a unique slot index, then the hash function is known as a perfect hash function. 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.
