Decode Jenkins Password

Reference:https://devops.stackexchange.com/questions/2191/how-to-decrypt-jenkins-passwords-from-credentials-xml

1. In Jenkins, go to: /script page.
2. Run the following command:

   println(hudson.util.Secret.decrypt("{XXX=}"))
   

   or:

   println(hudson.util.Secret.fromString("{XXX=}").getPlainText())
   

   where {XXX=} is your encrypted password. This will print the plain password.
   To do opposite, run:

   println(hudson.util.Secret.fromString("some_text").getEncryptedValue())
