Detailed explanation-1: -An encryption algorithm is the method used to transform data into ciphertext. An algorithm will use the encryption key in order to alter the data in a predictable way, so that even though the encrypted data will appear random, it can be turned back into plaintext by using the decryption key.
Detailed explanation-2: -Encryption algorithms are a mathematical formula which, with the help of a key, changes plaintext into ciphertext. They also make it possible to reverse the process and revert ciphertext back into plaintext. Examples of common encryption algorithms: AES.
Detailed explanation-3: -Ciphertext is encrypted text transformed from plaintext using an encryption algorithm. Ciphertext can’t be read until it has been converted into plaintext (decrypted) with a key.
Detailed explanation-4: -Data Encryption is the process of protecting and securing data by encoding it in such a way that it can only be accessed or decrypted by someone who has the encryption key. In Data encryption, the data is scrambled before it is sent to the person who can unscramble it using a key.
