Yup.

Nope -- not without massive re-code.

If not lazy, they were like other beginners in crypto.  Everybody seems to
go through the same learning curve.  At each stage, you're convinced that
your algorithm is so complex no one will be able to crack it.  Once someone
does, it's back to the drawing board.  This is why it's strongly
recommended that a person break several cryptosystems before attempting to
design one of his/her own.
