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. A cryptoperiod is the time span during which a specific cryptographic key is authorized for use. Common government guidelines range from 1 to 3 years for asymmetric cryptography, and 1 day to 7 days for symmetric cipher traffic keys. Factors to consider include the strength of the underlying encryption algorithm, key length, the likelihood of compromise through a security breach and the availability of mechanisms of revoki…
