1. The initial encryption standard developed by NIST was called data encryption standard (DES). DES is too weak for modern applications since the key size is only 56-bit. It was replaced by advanced encryption standard (AES). AES has variable key sizes and can require a key size of 256-bit. Discuss if you think AES key size has a direct relationship with algorithm strength
2. What are the advantages and disadvantages of using Asymmetric encryption?
