I have been working with a fairly simple-minded encryption scheme of my
own design for a year or so now. I know that it's not too hard to crack,
but it does allow for very large keys and defies simple frequency &
distribution attacks. I use it because there are times I don't have access
to the UN*X 'crypt' program and need to hide some data from other people on
the system (private letters, personal financial plans, &c.) In the process,
I started wondering about encrytion in general. Specfically, how much
harder is it to decrypt something if you don't know what algorithm was used?
I don't have a very strong mathematical background, so please keep your
answer/proof simple. An answer like "n orders of magnitude" and some simple
reasons will do. As always, email to me and I will summarize what I get (if
anyone's interested).
Thanx.
