Answer:
security/protection
Explanation:
The main purpose of a data encryption algorithm is security/protection. These algorithms grab data and change it into indecipherable code. This code can only be decrypted using a key that has been uniquely created for that exact piece of data. Usually, when the encrypted data and key have been created the key is given to the select few that need to have access to the data. This process helps protect the data from being seen or manipulated by unwanted parties.
