Encrypt Fields on Custom Objects and Custom Fields

You can encrypt standard fields on custom objects, and custom fields on both standard and custom objects, from the management settings for each object. For best results, encrypt the least amount of fields possible. When you add encryption to a field, all new data in that field is encrypted.
Available as an add-on subscription in: Enterprise, Performance, and Unlimited Editions. Requires purchasing Salesforce Shield. Available in Developer Edition at no charge for orgs created in Summer ’15 and later.
