Password Encryption in XML File

I am unable to encrypt password of sqlserver database in XML file by Package Configuration in SSIS.

I think that is not possible (though it might be possible if you develop something). According to the SSIS help you can either save the config file in SQL Server or use Windows access control lists to protect access to your config file. See ms-help://MS.VSCC.v80/MS.VSIPCC.v80/MS.SQLSVR.v9.de/extran9/html/2e3ddea9-5289-4289-a70e-11c018f34977.htm|||Yes in config file i have to put the password manually in config file.If i choose only connection string property in configuration wizard then it is working fine.But When i reset the server password then it fails.So i have to give the password.But unable to encrypt it for security reasons.
