WebThe one-way hash function is designed in a way that is difficult to reverse the process, ie to find the circuit at a certain value (hence it is called one direction). The hash function is good if it is difficult to find 2 strings that will produce the same hash value [8]. The way the hash function works is shown in Figure 2. WebJames M.
