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.
