In , is the conversion of into a coded text or . A ciphertext is intended to be unreadable by unauthorized readers. cryptography encryption cleartext ciphertext Encryption is a cryptographic primitive: it transforms a plaintext message into a ciphertext using a cryptographic algorithm called a . ncryption in modern ciphers is performed using a specific algorithm and a secret,  called the . Since the algorithm is often public, the key must stay secret if the encryption stays secure. cipher key Without knowing the secret, the reverse operation, , is mathematically hard to perform.
