Your application retrieves sensitive encrypted data from a data source and decrypts it. You need to minimize risk that a malicious program could retrieve the decrypted text after it is used because the application cannot delete the data from computer memory.

Which class should you use to store the decrypted text?

The SecureString represents text that should be kept confidential. The text is encrypted for privacy when being used and deleted from computer memory when no longer needed. If a String object contains sensitive information, such as a password, credit card number, or personal data, there is a risk that the information could be revealed after it is used because the application cannot delete the data from computer memory. Because the SecureString is deleted when it is no longer needed, you can avoid this risk.
