What is the difference between "cipher" and "encryption"?

WebThe science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext. The formulas used to encode and decode messages are called encryption algorithms, or ciphers. To be effective, a cipher includes a variable as part of the algorithm. WebTypes of Cipher.
