WebOct 9, 2024 · The hash function is a type of mathematical function, which, when applied to a digital file (record), assigns it a specific value called a hash (or “hash value” or “hash code”). A hash is a sequence of letters and numbers of set length that may be termed the “digital fingerprint” of a computer file. Examples of hashes are given ... WebJan 2, 2024 · The purpose of sharing fingerprints is to make sure that particular public key really belongs to particular person. When you want to encrypt a message to some person, you ask this person for a public key and receive it per Email. For some persons, e.g. for some developers, you can find their public key on different online resources.
