In cryptography, what is cipher?a)algorithm for performing encryption ...
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.When using a cipher the original information is known as plaintext, and the encrypted form as ciphertext.

Cipher in Cryptography
Cipher is an algorithm or method used in cryptography for performing encryption and decryption of data. It is a technique used to transform plaintext into ciphertext and vice versa.
Encryption and Decryption
Encryption is the process of converting plain text into an unreadable format, called ciphertext. The ciphertext is then transmitted over a network or stored on a device. Decryption is the process of converting the ciphertext back into plain text.
Types of Ciphers
There are two types of ciphers:
1. Symmetric Key Cipher - In this type of cipher, the same key is used for both encryption and decryption. Examples include AES, DES, 3DES, etc.
2. Asymmetric Key Cipher - In this type of cipher, two different keys are used for encryption and decryption. Examples include RSA, DSA, etc.
Uses of Cipher
Ciphers are used for secure communication, data storage, and authentication. They are also used to ensure the confidentiality, integrity, and authenticity of data.
Conclusion
Cipher plays an important role in cryptography as it provides a secure way of transmitting and storing data. It ensures that the data is protected from unauthorized access and maintains the privacy of the user.
