WebCiphers, also called encryption algorithms, are systems for encrypting and decrypting data. A cipher converts the original message, called plaintext, into ciphertext using a key to determine how it is done. Ciphers are generally categorized according to how they work and by how their key is used for encryption and decryption. Block ciphers ... WebWhat Is Encryption? Encryption is the process of converting or scrambling data and information into an unreadable, encoded version that can only be read with authorized access. Encryption is a widely used security tool that can prevent the interception of sensitive data, either while stored in files or while in transit across networks.
