Cryptography is the writing and decoding of secret messages, called ciphers. Now  for governments these secret ciphers are a matter of national security. They hire special cryptanalysts who work on these ciphers using cryptanalysis. The secret is, solving substitution ciphers can be pretty entertaining! Ciphers are published daily in newspapers everywhere. If you practice encoding and decoding ciphers, you too can become a really great cryptanalyst.


In this video, I’ll show you how to use the Rail Fence Cipher. Before you start, say this three times fast: cryptanalysts use cryptanalysis to crack ciphers!

    In your Forensics program, you have Cryptograpgy listed twice in the right side tool bar. They are exactly the same thing. Just thought you might want to know.

  2. Hi ,

    My name is Adam Nosterud. I am 12 years old. I made this code and I wondering if you are interested in it.
