Encrypting string in config file

[gibbie99]

I am installing a .NET program that has database credentials. I want to encrypt the password within the config file for obvious reasons.

I don't see a great way to do this from installaware though. I have a dialog that gets the database information from the user, and that works just fine, populating the $PASSWORD$ variable that i create.

I can't seem to run a program to do the encryption, because there is no way to return the data back (I can only return the exit code, not output). I do not know enough about C++ to generate a native DLL (and I'm not sure that would work anyway).

I really just want to call a program and get a string back, then I can create the config file by the "Write text to file" installaware command.

Any ideas?

I solved this by re-working my wrapper program to handle output to a file - this now saves the encrypted password directly to the config file.

Here is the encrypt class http://stackoverflow.com/questions/2020 ... t-a-string

And here is my wrapper class attached.

Also here is the installaware code that calls my program.
