WebOne of the approved symmetric-key algorithms for encryption/decryption is the AES. AES is a block-cipher algorithm, which operates on blocks of data during encryption/decryption operations. The AES algorithm encrypts and decrypts information in 128-bit blocks while using 128, 196, or 256-bit keys, which are specified within FIPS PUB 197. WebSearch the Internet for information regarding cryptoperiods for hash, symmetric, and asymmetric algorithms. Find at least three sources for each of the algorithms. Draw a table that lists the algorithms and the recommended time, and then calculate the average for each. Do you agree or disagree? new twin tower name
