WebNIST looks to the future to make sure we have the right cryptographic tools ready as new technologies are brought from research into operation. For example, NIST is now working on a process to develop new kinds of cryptography to protect our data when quantum computing becomes a reality. Key size is the number of bits in the key defined by the algorithm. This size defines the upper bound of the cryptographic algorithm's security. The larger the key size, the longer it will take before the key is compromised by a brute force attack. Since perfect secrecy is not feasible for key algorithms, researches are now more focused on computational security. In the past, keys were required to be a minimum of 40 bits in length, however, as technology adv…
