As you probalbly know, there are some passwords/entries in WSO2 configuration files that are stored in plain text when you install WSO2 products.

My colleague Jan Timmerman has written a blog about it, if you want to know more about Secure Vault and the encryption of passwords in the WSO2 configuration files, have a look here.
