Overview of Bring Your Own Key (BYOK)
Note: To use key management, it needs to be enabled for your organization. For more information, see the BYOK Overview page.
What is key management?
With Key Management, you can bring your own key (BYOK) to encrypt files and data. This allows you to retain control and management of your data by using your own encryption keys or the Wdesk key generator. By default, all files and data are encrypted, but some organizations prefer to manage and retain control of data encryption.

Best practices
As you prepare to get started with key management, here are a few best practices:
- Start with your security requirements
Your company’s security requirements and processes determine how and when you interact with Bring Your Own Key. When uploading your own key encryption, plan on how you will store your key based on your security guidelines. Then, create a plan for how you will manage uploading, rotating, or removing your encryption key to ensure that you follow your organization's security requirements. -
Try out key management first
If you are interested in trying out Bring Your Own Key, contact your Customer Success Manager (CSM) before you add or generate a key for your organization. We can create a place for you to test generating and adding a key so you can gain confidence in the process before you add an encryption key for your organization. -
Perform key management after hours
We recommend that you do any key management actions, such as generating, adding, or rotating a key, outside of your normal business hours. Typically there aren't any issues, but it's a best practice to not create or update new data as you add or change an encryption key. -
Select two people to manage your key
We recommend that you assign at least two users with the Org Security Admin role to manage your encryption key. This allows you to have a backup in case one is not available. Also, it's common for the primary Org Admins to have the Org Security Admin role, so they can see if BYOK is active, but they would be unable to manage the key without access to the key material.
Key guidelines
When you create an encryption key, make sure you have a plan in place for the management and retention of it. Workiva does not keep a copy of your key and you need to make sure you keep it. As a general guideline, work with your company’s information security team for the proper way to generate and store encryption keys. You can upload any file type, as long as it contains binary key content.
Key requirements (Only applies to uploading your own key):
- 256-bit symmetric encryption key
- Exactly 32 bytes
- Meets cryptographic randomness
When you upload a key, it is checked to make sure it meets the requirements listed above. This ensures you can generate and test that you have a valid key before you confirm and make it active for your organization.
Monitor key activity
All of your key management actions are logged as organization activities, so you can track any time a key is added or modified. Key management activities show as the type of Control and you can click details to see the specific action.
