Please remove DES as it is insecure. For discussion, see:

It's fine for testing purposes, leave it in.

absolutely. it could also be needed for interoperability, or many other
valid uses that might not depend on its sheer strength as a cipher.

"but you shouldn't be interoperating with things that are insecure!"

blah blah blah. that is not the kernel's decision to make. meaningful
security is defined by much more than context-free assertions. warn
against its naive use, avoid it being a default, but allow the clued to
use it easily when it makes sense.
