4096 SSL keys

Hi,

 

 

I implemented a cert/key to my LTM 9.4.6 and when I try to create a SSL profile it shows: 4096 bit keys are not supported

 

Is this mean that I have a problem?

 

I guess 4096 key are not supported and I need to downgrade my cert to 2048?

 

How can I check what kind of keys are supported on my box?
