encrypting web.config in web farm

Question

I want to encrypt the connectionstrings in my web.config. And my application will be deployed in web farm.

I tried reading some blogs about this, but got confused.

Can somebody tell me a link which they have really tried and got succeded.

Answer 1

We use the RSA Protected Configuration provider. That page isn't light reading, but it's got what you need.

I recommend the command like so (example from the article):

aspnet_regiis.exe -pef "connectionStrings" C:\Projects\MachineRSA
