AES256 and AES128 are newer enctypes because they are officially specified in RFC4120 and RFC8009, while enctypes not officially specified since RFC4120 are considered older. This function differs from older_enctype() in that it does not report unknown or non-existent enctypes as being 'newer'. Signed-off-by: Joseph Sutton <josephsutton@catalyst.net.nz>
