Our Secret Codes Section
Why have a section on secret codes on a brainpower enhancement
web site? Because doing cryptograms or inventing your own ciphers
and codes is great brain exercise. More pages of cryptograms
will be added here in the future, but what we have now is linked
to below.
You'll also find pages with a bit of the history of Cyphers,
crytograms and codes, and pages explaining basic code breaking
and code making. Enjoy.
Code Breaking - One of the
basic tools used in cryptanalysis (code breaking) is letter frequency
analysis. This page has a letter frequency table showing the
average percentages for the use of letters in English. There
is also a two-paragraph message in code for you to try breaking.
More on How to Break Codes
- This is a continuation of the Code Breaking page, with the
solution to the coded message, along with a short lesson on how
to use letter frequency to break a code.
Cryptograms - One of the oldest
versions known was a strip of paper wrapped around a stick. You'll
learn about that and Caesar ciphers here.
Ciphers or Cyphers? - What is the
difference between a cipher and a code? A few definitions are
covered here, as well as more information on how to create a
secret code.
Cryptogram Puzzles -
There are two cryptograms here. One is a very simple Caesar cipher,
while the more difficult one uses numbers as substitutes for
letters.
Cryptogram Solutions
- The solution to the above puzzles are here. More importantly,
there are detailed explanations of how to solve them.
Codes and Ciphers - This
page is all about how to make secret codes that are simple, yet
very difficult to break.
Notes:
New pages of cryptograms and ciphers will be listed here,
so check back. They also will be announced in The Mind Power
Report. You can subscribe on the home page or using the form
in the sidebar to the left.
The secret codes covered here are essentially pre-computer
encryption algorithms. They are fun, and great brain exercise,
but they won't teach you much about the cryptanalysis of modern
algorithms. On the other hand, if you are going into the field
of encryption, this practice will get you in the right frame
of mind.
