Mule Secure Properties Preview

VS Code extension for previewing, encrypting, and decrypting MuleSoft secure properties in .yaml, .yml, and .properties files.

Setup

1. Open a YAML or properties file and run Mule Secure Properties: Secure Preview, or click Secure Preview in the editor title.
2. In the Secure Preview UI, choose or browse to secure-properties-tool-j17.jar, then click Save.
3. Select a secure key profile such as dev, qa, or prod.
4. Enter that profile's secure key and click Save key.

The extension runs the MuleSoft Java 17 command shape:

java -cp secure-properties-tool-j17.jar com.mulesoft.tools.SecurePropertiesTool string encrypt Blowfish CBC <key> <value>

For whole-file actions, the default method is file, which transforms all property values in the file. Set muleSecureProperties.fileMethod to file-level only when you want the tool to transform the entire file content as one encrypted payload.

Behavior

• The JAR path is saved automatically to VS Code workspace settings.
• Secure key profile names are saved in settings, but key values are stored in VS Code SecretStorage, not plaintext settings.json.
• You can add/delete secure key profiles such as dev, qa, prod, uat, or stage.
• Encrypt actions wrap returned values as ![...].
• Decrypt actions unwrap ![...] before sending values to the CLI.
• Apply changes only after preview. The source editor is updated but not automatically saved.
