How to decrypt WebLogic passwords with WLST?
Sooner or later you will find the situation where you do not remember any of the WebLogic Server password’s stored in the configuration files.

Some examples are:
a) The WebLogic Server administrator credentials (username and password) stored in the files config.xml and boot.properties
b) Node Manager password, stored also in the config.xml file (if you still have the default password, don’t wait and change it know!!)
c) Database password used by the JDBC Data Sources and stored in the file [DOMAIN_HOME]/config/jdbc/[datasource_name].xml

3.Run the script.
Go to the path where you copied the WLST script ( decryptPassword.py) and run it.

You must provide two arguments, the WebLogic Server domain Home full path and the string you want to decrypt.
