Which of the following statements is true about encrypted fields?

The statement that encrypted fields cannot be included in search results is accurate. When a field is encrypted in Salesforce, it is designed to ensure that sensitive information is protected, limiting how it can be used in various functionalities like searching. Encrypted fields remain secure by not being indexed, which prevents them from appearing in search results, list views, or reports that involve searching on those fields.

This restriction is crucial for maintaining data security and privacy, as it prevents unauthorized access to sensitive information. The nature of encryption requires that only users with the appropriate permissions can view the encrypted data, which aligns with the organization's need to safeguard sensitive information while still allowing for data management in compliance with security standards.
