![]() In disk encryption, the whole data is encrypted and decrypted using the same key, thus it makes use of symmetric encryption. If the encryption process uses the same key to encrypt and decrypt the data, it’s called symmetric encryption and if the keys are different then it’s called asymmetric encryption. The encryption process makes use of symmetric and asymmetric encryption for encryption and decryption of data. Using modern encryption algorithms, it is not easy or feasible to decrypt encrypted data, thus a breach of encrypted data is not considered reportable by many regulatory authorities. Encrypted text hides the original data from unauthorized users since encrypted text cannot be read by anyone. Encryption is the process of converting plaintext to encrypted text.
