Data transformation and encoding before uploading to the cloud is known as cloud encryption. Using mathematical methods, this procedure turns plaintext data into unintelligible ciphertext, shielding it from unwanted and potentially dangerous users.
Before data is sent to and stored in the cloud, it must first be converted from its original plain text format into an unintelligible format, such as ciphertext.
Cloud Encryption, like all data encryption methods, makes the data unreadable and consequently unusable without the encryption keys. Even if the data is misplaced, taken, or disclosed to an unauthorised user, this still holds true.
