Indeed. Mostly, it&#x27;s just a question of whether or not the software will support a key of such size. Typically, I would recommend that, unless you&#x27;ve a good reason to use a smaller key (like support concerns), one should use the biggest key one possibly can use at the time the key is generated. Though, if one is doing key rotation as one should be, one can always adjust up as needed as time goes on.
