Qlik Sense Enterprise on Windows: MISSING_ENCRYPTION_KEY when creating a data connection

Nao_Baba — Wed, 17 Dec 2025 09:47:51 GMT

Most Qlik Web Storage Provider Connectors require an encryption key. If no key exists, the following error will be displayed when authenticating:

Error retrieving the URL to authenticate: ENCRYPTION_KEY_MISSING - you must manually set an encryption key before creating new connections.

Resolution

General information, as well as a list of which connectors require an encryption key, can be found in Setting an encryption key | Qlik Connectors Help.

The actual generation of a key depends on your organization's best practices, but we can provide you with an example on how to go about it with OpenSSL:

The below example is not supported by Qlik Support. Review it with your local security office to see what method your organization follows.

Download and install OpenSSL.
See https://slproweb.com/products/Win32OpenSSL.html
Open the OpenSSL folder (default C:\Program Files\OpenSSL - Win64\bin).
Open the command prompt as an administrator and run these commands:
1. cd C:\Program Files\OpenSSL -Wind64\bin
2. openssl rand -base64 256
Copy and save the successfully generated key.
Follow the instructions on how to set the encryption key in Qlik Sense Enterprise on Windows and/or Qlik Sense Desktop:

Hi @Nao_Baba,

Thanks for making this post! Can you please provide any context as to why encryption key is required?

I'm looking to learn and understand what role an encryption key plays when data connections are made. Using your example, if I'm making a connection from my on-prem Qlik Sense server to Google Drive, where does encryption key come to play?

Thanks,

Mikhail B.

Copying the answers from a different post:

Data Connection Encryption uses symmetric encryption, correct
Data and encrypted in transit
Credentials are also encrypted
The encryption keys for data connections are required for specific connectors to adhere to security standards. See Connectors that require an encryption key on which ones require one

All the best,
Sonja

Hi @Sonja_Bauernfeind - i recently added the encryption key using the

QvWebStorageProviderConnectorPackage.exe /key <enKey> command.

But after that only one file got generated qseow_prm.

I see other two files entrpoy & qseow_tmp - which didnt generate newly.

Also after this I cannot see the 365 connector in the create new connection box.

Could you please help
