symmetrical encryption (Symm crypto)lists the secret key encryption (Secretkey Encryption).Also, the encryption, called “Single key encryption) to use only a shared secret (Sring clear-key Encryption).Consequently, the symmetry encryption method is different from an asymmetric encryption using one-to-key (one and private key) to encrypt messages.symmetrical key encryption is easy and easy to use one problem.People who receive data to share the key to share the key.The method of thinking about how to replace key to secure the key.If the third party is replaced by the third party, the people who can easily read information.Symmetric Encryption is also referred to as secret key encryption. In addition, it is also called single-key encryption because only “one key” called shared secret is used for both encryption and decryption. Thus, symmetric encryption is different from asymmetric encryption, which uses a pair of keys (one public key and one private key) to encrypt and decrypt messages.Symmetric key encryption is a simple and easy-to-use encryption method, but it has an essential problem. It means that the sender and receiver of the data should share the key. It is necessary to devise a way to safely exchange keys between each other. This is because if a third party steals the key during the exchange, even those who do not have the authority to read the information can easily decipher the data.Symmetric Encryption is also referred to as secret key encryption.
