Detailed explanation-1: -In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.
Detailed explanation-2: -Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. This process prevents the loss of sensitive information via hacking.
Detailed explanation-3: -The symmetric key is a string used to encrypt the data, and with the exact string, we can decrypt the data, which means a single string is required for encryption and decryption.
Detailed explanation-4: -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.
