I got a problem when developing SSIS packages.
For security reason, the sensitive information must be encrypted, and they should be configurable dynamically (by an ASP.NET application).
so I tried several ways to achieve this,
1. use SSIS Package Configurations to generate an XML config file
It's a convenient way to generate config file. but the passwords are not encrypted (or I don't know how).
2. use Variables and Property Expressions
I can set variables by reading from an external custom xml config file which was content encrypted (read and decrypt the custom config file in a script task). but in a FTP Connection Manager entity, the Password property can not be set via Property Expressions.
Is any way to store password encrypted to an external file

Is it possiable to store password encrypted to an external config file?

Public Sub Main()
'a custom class to read my custom config file
Dim c As Config = Config.GetConfig()
Dts.Variables("FtpServerIP").Value = c.Settings("FtpServerIP")
Dts.Variables("FtpServerPort").Value = Convert.ToInt16(c.Settings("FtpServerPort"))
Dts.Variables("FtpServerLogin").Value = c.Settings("FtpServerLogin")
Dts.Variables("FtpServerPassword").Value = MyDecryptMethod( c.Settings("FtpServerPassword") )
Dts.Connections("FTP Server").Properties("ServerPassword").SetValue(Dts.Connections("FTP Server"), Dts.Variables("FtpServerPassword").Value)
Dts.TaskResult = Dts.Results.Success
End Sub
Now I can store and encrypt my password or other sensitive information in a custom XML config file, and change it dynamically. It looks quiet complex, but it's the only way I know.
Any good suggestion
