WebA cryptographic hash function should be computationally efficient, meaning that it must be quick in performance to create the hash value. It has to be deterministic - every time you put in a certain input, it has to produce the same output and to be pre-image resistant which means it cannot reveal any information about the input in the output.

WebThe meaning of "hard" The basic question is the meaning of "hard". There are two approaches to answer this question. First is the intuitive/practical approach: "hard means that it is almost certainly beyond the reach of any adversary who must be prevented from breaking the system for as long as the security of the system is deemed important." WebDigital signature is a technical term, defining the result of a cryptographic process or mathematical algorithm that can be used to authenticate a sequence of data. It's a type of electronic signature. The term electronic signature, or e-signature, is a legal term that's defined legislatively.
