* I'd still like to know if it's possible to enable to both. If it's not, though, then which one is best to enable? MD2 or RC5? Thanks in advantage for the reply and sorry for the new email thread.
They do different things; MD2 is a digest (“hash”) function, and RC5 is a block (encrypt/decrypt) cipher. Both are obsolete. You should be able to enable both, but you should only do so if you need to work with some really old software.
