Issue
After importing a database dump from Production to Staging/Integration environments, saved credit card numbers appear wrong and/or payments fail for payment integrations requiring usage of merchant credentials.
Cause
The encryption key used to encrypt sensitive data, like credit card numbers and merchant credentials, is not stored in the database, and therefore does not get transferred to other environment after database dump import/export.
Solution
You need to copy the encryption key from the source environment and add it to the destination environment.
To copy the encryption key:
- SSH to your project that was the source for the database dump, as described in SSH to environment in our developer documentation.
- Open
app/etc/env.phpin a text editor. - Copy the value of
keyforcrypt.
return array ('crypt' => array ('key' => '<your encryption key>', ),);
To set the key value for the destination project:
- Open the and locate your project.
- Set the value of the CRYPT_KEY (in our developer documentation) variable, as described in Configure your project in our developer documentation. This will trigger the deployment process and
CRYPT_KEYwill be overridden in theapp/etc/env.phpfile on every deployment.
Optionally, you can manually override the encryption key in the app/etc/env.php file:
- SSH to the destination environment.
- Open
app/etc/env.phpin a text editor. - Paste the copied data as the
keyvalue forcrypt. - Save the edited
env.php. - Clean cache on the destination environment by running
bin/magento cache:cleanor in the Commerce Admin under System > Tools > Cache Management.
