Secure Properties API Web Interface 504 Timeout: Use the Supported CLI Tool

The following Secure Properties API web interfaces are internally maintained convenience tools and are not officially supported services. Therefore, they do not have guaranteed uptime or an SLA, and users may occasionally experience a 504 Gateway Timeout:

• https://secure-properties-api.us-e1.cloudhub.io/
• https://secure-properties-api-ch.us-e2.cloudhub.io/

In such cases, users and customers are advised to use the officially supported Secure Properties Tool CLI to encrypt their secure properties locally. It provides the same result as the web interface and works entirely offline.

The good news is you can encrypt your secure properties locally using the official command-line tool,
which is the documented and supported method:

1. Download the JAR from the Exchange or the documentation page:
https://docs.mulesoft.com/mule-runtime/latest/secure-configuration-properties#secure_props_tool

2. Run the encryption command:

java -cp secure-properties-tool.jar com.mulesoft.tools.SecurePropertiesTool \
string \
encrypt \
<algorithm> \
<mode> \
<key> \
<value>

For example, to encrypt with AES/CBC:

java -cp secure-properties-tool.jar com.mulesoft.tools.SecurePropertiesTool \
string \
encrypt \
AES \
CBC \
myEncryptionKey123 \
"valueToEncrypt"

This gives you the same result as the web UI and works entirely offline.
