Answer:

A combination of encryption nd decryption algorithm is called as cipher

Explanation:

Cipher

  • Systems for encrypting and decrypting data are known as ciphers, often known as encryption algorithms.
  • A cipher uses a key to reveal the process by which it transforms the original communication, known as plaintext, into ciphertext.
  • Ciphers may generally be divided into groups based on how they operate and how their key is applied to both encryption and decryption.
  • For encryption and decryption, asymmetric key algorithms or ciphers employ distinct keys.
  • There are both basic and complicated algorithms for ciphers.
  • One method is used for encryption, another for message authentication, and a third for key exchange in a cypher suite.

Cipher used two important types of transformation.

  • Transformation cipher
  • Substitution cipher

Transformation cipher:

Transformation cipher which keep all the original bits of data in the byte but mix their order.

Substitution cipher:

Substitution cipher which replace specific data sequences with other specific data sequence.
