That is true, the issue being that some software and hardware platforms do
not support RSA keys above 2048bit as of now.
I mean - I do not really have an issue with discussing to put 3DES in
there. We were a bit time restricted to do our research (i.e. we limited
ourselves to certain ciphers) and since this is still in draft stage we're
able to change things like that.
Input from anyone else on the list?
