Data encryption


Applies To: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online


The information provided here is for versions of Dynamics 365 prior to Dynamics 365 (online), version 9.0. For the latest documentation, see Enhance security by encrypting your data.

Microsoft Dynamics 365 uses standard Microsoft SQL Server cell level encryption for a set of default entity attributes that contain sensitive information, such as user names and email passwords. This feature can help organizations meet FIPS 140-2 compliance.

For Microsoft Dynamics 365 (online) and Dynamics 365 (on-premises), all new and upgraded organizations use data encryption by default. Data encryption can’t be turned off.

Microsoft Dynamics 365 users who have the system administrator security role can change the encryption key at any time. More information: Change an organization encryption key


For on-premises versions of Microsoft Dynamics 365:

  • Changing the encryption key requires TLS/SSL configured on the Microsoft Dynamics 365 website.

  • It is a best practice is to change the encryption key once every year.

  • The encryption key is required to activate data encryption when you import an organization database into a new deployment or a deployment that has had the configuration database (MSCRM_CONFIG) re-created after the organization was encrypted. You can copy the original encryption key to Notepad and paste it into the Settings > Data Management > Data Encryption dialog box after the organization import is completed.

  • When you re-enter the data encryption key, we recommend that you run the Microsoft Dynamics 365 web application using Internet Explorer to paste the encryption key into the Data Encryption dialog box.

Change an organization encryption key

  1. Go to Settings > Data Management.

  2. Click Data Encryption.

  3. In the Change Encryption Key box type the new encryption key and then select Change.

  4. Select OK in the confirmation message and then click Close to exit the Data Encryption page.

  5. We recommend that you copy the key to a safe place. Copy your organization data encryption key

Copy your organization data encryption key

We strongly recommend that you make a copy of your data encryption key. This is particularly important for on-premises deployments that may need to reactivate data encryption after a redeployment or failure recovery.

  1. Sign in to Microsoft Dynamics 365 as a user with the system administrator security role.

  2. Go to Settings > Data Management.

  3. Click Data Encryption.

  4. In the Data Encryption dialog box, select Show Encryption Key, in the Current encryption key box select the encryption key, and copy it to the clipboard.


    When the Dynamics 365 (on-premises) website is not configured for HTTPS, the Data Encryption dialog box will not be displayed. For a more secure deployment, we recommend that you configure the website for HTTPS. However, if the website is not configured for HTTPS, use a tool that can be used to modify Dynamics 365 database tables, such as Microsoft SQL Server Management Studio or the Deployment Web Service, open the configuration database (MSCRM_CONFIG), and in the DeploymentProperties table, set DisableSSLCheckForEncryption to 1.

  5. Paste the encryption key in to a text editor, such as Notepad.


    By default, Microsoft Dynamics 365 generates a passphrase that is a random collection of Unicode characters. Therefore, you must save the system-generated passphrase by using an application and file that supports Unicode characters. Some text editors, such as Notepad use ANSI coding by default. Before you save the passphrase using Notepad, select Save As, and then in the Encoding list, select Unicode.

  6. As a best practice, save the text file that contains the encryption key on a computer in a secure location on an encrypted hard drive.
