What is encryption of cipher?

cipher encryption is a series of encryption where the key to protect coded information is used. In general, there are two methods of encrypting encryption - block and current method. They determine how the cipher is applied to the original message. In addition to these two methods, there are two styles. The cipher is either symmetrical or asymmetrical depending on whether the message requires the same or other decryption cipher.

The encrypted reports were the foundation of human secrets from early civilization. Methods came and left to maintain important missiles safe, but most of them were some encryption encryption. Methods of using a pre -marked key to coding and decoding messages have occupied the lives of many people. In the first days, these keys were complicated only on the basis of low user technology; Now there are supercomputers who do nothing but encryption and decrypting messages. The cipher block encodes the information in predetermined blocks sizes. If the cipher is designed to encode 200 characters, this is exactly what the worksand. If the message is longer, it must be divided into multiple pieces and, if shorter, requires padding characters. A padding character is a character that simply extends the message; It can be anything from the stream of individual characters to a random range of letters and spaces.

Stream Ciphers are computer age innovation. This encryption style generates and adapts its coding string as it works. This encryption method uses the current state of the machine to generate the cipher.

This method is constantly changing to match the current state of the system. The Cyphers stream is almost unbreakable unless two things happen; The code cannot be repeated, and the non -disclosure that captures the message may know any of its content. If the code is repeated, it is possible to break the sequence with small efforts due to the brands that remain in the ciphers. If an interceptor knows any content content, it can edit the message without opening itof it.

In the symmetrical ciphers, the key is used to coded the message the same as the key used to decode message. These ciphers are simple and easy to create, but the key is in danger because it moves from place to place for decoding. In addition, if any of the key points is disturbed, the whole cipher is destroyed.

Asymmetrical cipher encryption uses two keys, one that encodes the message and the other that decodes the message. This is the cornerstone of public keys encryption. The message is created from two keys, public and private. In this case, the keys interact to allow a specific person to unlock the message without knowing the actual encryption key.
