Hi,
I have an application which needs to encrypt and decrypt the connectionstring in web.config file

like i had login and logout page.

so i dont know where to place encrypt and decrypt the login credentials
so i placed encypt code i login page and
decrypt code in logout page

is it right to place like this.

and also one more thing if i encrypt it dynamically changes the web.config file so all my session values are becoming null why?

this is my connectionstring

<connectionStrings><add name="Conn" connectionString="DataSource=northwind;server=myserver;User ID=test;Password=test"providerName="System.Data.SqlClient" /></connectionStrings>

Thanks
Srinivas
