Detailed explanation-1: -Encryption is a way of scrambling data so that only authorized parties can understand the information. In technical terms, it is the process of converting human-readable plaintext to incomprehensible text, also known as ciphertext.
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: -The formulas used to encode and decode messages are called encryption algorithms, or ciphers.
Detailed explanation-4: -Scrambling and descrambling are also known as “encryption” and “decryption, ‘’ respectively. So, for instance, the written message “I LOVE YOU, ‘’ when it is scrambled by the sending party, becomes what is known as the “encrypted message” (this is the encryption step).
