Disabing rc4 and des in win 2012 production spl

The customer have SQL production servers n windows 2012.

They came with the question will there be any effect for SQL Servers if we disable both RC4 and Des.

I am not sure what can happen to the application if we disable this both. I dont have any idea on these. Please can anyone guide how to disable if these both will not impact the SQL Server.

It depends.

  1. Is it being used in SQL server if so how
  2. If not in SQL in What layer are you using it and how
