- under the title "A Simple Code". Can you solve it?

I would certainly agree that most of the time that is spent decrypting something is spent using the wrong methods... people don't generally attach the exact algorithm to their message.
There are also some systems that cannot be decrypted, because you cannot be certain that you have obtained the correct message, rather than another set of characters of the same length that happens to make sense. I am referring to what is known as a onetime pad, which is actually relatively simple to implement.

If you do NOT know how the plain text was enciphered, you may expend enormous resources with no discernible benefit.
AFTER you know the method used to encipher the plain text, it is possible to "waste" a lifetime using an inefficient decryption procedure.
Many newspapers publish a daily puzzle called cryptoquip [that may be a registered trademark].
It is a simple substitution cipher.
This is one of the results from google: http://cryptoquip.qarchive.org/
]]>What I'm really looking for is a site that will give me lengthy papers coded that I have to try and break using letter frequency and whatnot. Kind of like Project Euler for code breaking.
Anyone know of any sites/books that I could check out?
