How to configure secure properties in Mule 4 and access them through Runtime Manager

This tech article describes how to configure secure properties in Mule 4 and access them through Runtime Manager.

• Install the Mule Secure Configuration Property Extension from Exchange in the Mule Palette
  

  Once installed, you’ll see the Secure Properties option in Mule Palette:

  

• Create a properties file and define the properties that need to be secured.

  The example below shows a secure.properties file:

  

• Open the properties file with the Mule Properties Editor





• Double-click the Property Name and click Encrypt



• Select the Algorithm and note the key that will be used to decrypt the password in the future
  

  

  You’ll see the password is decrypted.

  

• Go to Global Elements or Config and create a Secure Properties Config



• Select the Algorithm, Key and File to be secured

  NOTE: Use an algorithm and key similar to what was used while encrypting the password in the prior step.

  

• In configuration, note the secure property: (secureProperty)
  

  If you want to encrypt the property in Runtime Manager properties, add a secureProperties key to mule-artifact.json.

  

  If you want to access or change the secure property in Runtime properties, use secure\:\:sap.password=************
