From current literature survey, critically analyses and discuss cryptoperiods for hash, symmetric, and asymmetric algorithms. Find at least three sources for each of the algorithms (select two algorithms from each category). 2. Draw a table to list the algorithms and the recommend time, and then calculate the average of each. 3. WebThe most important property of hash functions is the size of the hash. A larger hash makes it more difficult to invert the function, and it ensures that the function is collision free. Because hash functions have a fixed output but unlimited inputs, multiple values can produce the same hash. five star rated hair salons 28659
