These algorithms are not designed for efficiently protecting large amounts of data. In practice, asymmetric algorithms are used to exchange smaller secret keys which are used to initialize symmetric algorithms. Stream versus Block Ciphers There are two major types of ciphers: block and stream. Block...
Feeling responsible for the situation, they do not want to put that on them. When the company has a good hiring and interviewing practice, it rarely happens. We cannot avoid such situations, however. It is not because of the unique nature of the interviews. It is a general measurement ...
