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. WebUsing an OpenSSL message digest/hash function, consists of the following steps: Create a Message Digest context. Initialise the context by identifying the algorithm to be used (built-in algorithms are defined in evp.h) Provide the message whose digest needs to be calculated. Messages can be divided into sections and provided over a number of ...
