What is symmetrical cryptography?
symmetrical cryptography uses symmetrical key algorithms for encryption and decryption of data. The algorithm is a specific formula with a limited number of steps that contain instructions for solving the problem, and the symmetrical key algorithm is a specific formula that often uses the same cryptographic key for both encryption and decrypting. To better understand how it works, it helps to understand how cryptography works in relation to technology.
For example, a computer that needs to transfer sensitive information can opt for information encryption, which is a process that turns it into any kind of code that would appear as a bunch of nonsense if someone tried to read it. After transferring information to the required location, the specific code decrypts the information into a readable text. This process is known as decryption and the computer must have the correct code to properly perform this process. Banks that offer online services use forms of encryption on keep information of their customersPrivate and safe.
Mathematical formula known as a cryptographic algorithm is responsible for creating a code for encryption and code for its decryption later. Specific information known as the cryptographic key says the cryptographic algorithm to encrypt and then decode the specific information it receives. The key only works with this particular algorithm and would be unnecessary for the decryption code from another algorithm.
When using symmetrical cryptography, the algorithm uses the same cryptographic key to perform coding and decoding processes instead of using a separate key for each. The keys are usually identical or almost identical to only one small change needed to make each of them work. Usually, only those who plan to use the key will be known to know the password or other secret code or phrases needed for the cause key to start work. This allows two people to share an infOrmation among themselves without being afraid that someone else could capture the code and read it.
Other terms used to describe the algorithms of the symmetrical key used in symmetrical cryptography include secret key cryptography, private key cryptography and one -key cryptography. Symmetrical cryptography is usually used to share between two people or a small group instead of large online networks such as banks. For example, the ATM machine can use symmetrical cryptography and require the user to enter the bank account number and the personal identification number before allowing this person to access his account.
