be decrypted and is not transmitted over the network.Asymmetric algorithms are more costly and slow than symmetric algorithms. Therefore, we do not want to encrypt all information using asymmetric algorithms in online conversations. Instead, we use symmetric algorithms. In the following example, asymmetric encryption is used to encrypt symmetric keys. Then we use symmetric encryption. In fact, the security Interface Layer (SSL) is used to establish a server and install the security interface la

item length, which is similar to hash because the item length can be calculated, for example, if the length of an item is 300 bytes, we can see in 1.2 that it should be stored in slab of id7. Because the chunk size of id6 is 252 bytes according to the calculation method above, the chunk size of id7 is 316 bytes, And the chunk size of id8 is 396 bytes, indicating that all items between 252 and 316 bytes sho

example, if there are 13 hosts in total, it is a waste to use 255.255.255.0 when setting the subnet mask. We will set vlsm.13 The number of addresses in the subnet that is subtracted by 256 must be the Npower of 2 (n from 0 to 10 ).If the number of hosts is 13, and the number of unavailable network and broadcast IP addresses at both ends is 15 in total, select a 2 n value that is larger than 15 and closest to 15, that is, 16.If the host is 50, then 52 The following values are calculated from 0
