In the blog titled 'How to enable Secure Property Placeholder in MuleSoft', we have discussed how to encrypt properties and sensitive data that might float in and out of the applications and may be visible to the development and support teams.
Now we are here with a new post on how to enable Secure Property Placeholder in Mule 4, employing the latest security configuration module (Secure properties config) that will help protect sensitive data. This module is used to encrypt and decrypt information like passwords, SSN, Credit Card numbers and other confidential information.
For the purposes of this blog, we will be using password tokenisation as an example with Blowfish.js as the encryption algorithm and Anypoint Studio 7 as the development tool. At the end of the blog we also provide a brief outline on how to use different encryption algorithms.
Use the below expression in the Password text box.
${secure::mule4domain.secret.password}
How to use other encryption algorithms in Mule 4
Mule 4 supports various encryption algorithms like AES, Blowfish, RSA, DES and others as shown in the list below.
In order to use any of these algorithms in Mule 4, the steps are the same as they were in Mule 3, and you can find them here: Secure Property Placeholder in MuleSoft
