Lets say this is your connection string:

Then you can do something like this:

string myCs = System.Configuration.ConfigurationManager.ConnectionStrings["cs"].ConnectionString;

System.Data.SqlClient.SqlConnectionStringBuilder csb = new System.Data.SqlClient.SqlConnectionStringBuilder(myCs);
csb.Password = EncDecHelper.Decrypt(csb.Password);
myCs = csb.ToString();

You can write EncDecHelper.Decrypt by using samples from here: Encrypt and decrypt a string
