![]() ![]() Even though the public and private keys are different, they are related to each other so we call them a key pair. We use a public key for the encryption and a private key for the decryption. While in symmetric encryption we have only one key to encrypt and decrypt data, in asymmetric encryption, we use two different keys. It’s because of its dynamic and static cryptographic techniques that pave the way for more detailed classes, symmetric and asymmetric ciphers: The most common and used in digital are is modern class. ![]() They are mainly divided into two different types classical and modern classes. As we’ve seen, we categorize ciphers in terms of some characteristics that they have or according to their usage. In the figure below, we present the general view of the classification of the ciphers. Not only in the digital era but ciphers have also been widely used throughout history. What happens is that encryption provides transformations on the plaintext and transforms it into ciphertext which isn’t human-readable. ![]() Encryption is a technique for securing the information so only the authorized parties can interpret the data. ![]()
