Javascript secret code and cipher systems, created as a hobby while trying to decrypt the final section of Kryptos. However, the cipher systems found here apply to a lot of different famous codes. You can either pick your favorite cipher type and go from there, or try one of the famous codes that are built-in.

The following Encrypted Message System is useful for various types of Secret Code
and Cipher systems.

Some of the cipher systems implemented here are useful for solving:

many of James Sanborn's sculptures, inc. Kryptos, the
Cyrillic Projector, Antipodes,
Covert Ops Fragments (Zola Spy / English /
Cyrillic), and Binary Systems,

some of Simon Singh's "The Code Book" Cipher
Challenges (
1, 2, 3,
4, 5, 6,
7, 8, 9,
10),
(and the people who solved them CodeBook.org)

the Antilles Cipher Challenge http://www.ti89.com/cryptotut/challenge.htm

the Edgar A. Poe Ciphers,

at least one of the Beale Ciphers,

some of Dan Brown's Ciphers - The DaVinci Code, Digital Fortress,

the Smithy Code - from Judge Smith who ruled on the DaVinci Code trail,

Harry Potter and the Sorcerer's Stone, Mirror of Erised

at least one of the Feynman
Ciphers,

the Elonka Code,

John Wilson's RuneQuest Cipher Challenge,

Michelle Barette's Egyptian Pharaoh Cipher
Puzzle,

and perhaps others... (see Elonka's
list of Famous Unsolved Codes).

Engima Machine, ChaoCipher, M-94 Cipher Wheel, etc.

You can also find some frequency counters, digram counters, pair distance calculators,
avg IC calculation (Index of Coincidence), variance functions, etc...

You can find descriptions of some these code types at: http://www.cryptogram.org/cdb/aca.info/aca.and.you/chap08.html

Another excellent resource with many examples: The Crypto Tutorial - hint: the Mod-Trans/Linear-affine formula solves a lot of these...

And, of course,
Music for solving Secret-Codes!:

The easy way to see how things work is to use the
"Pick a code" drop-down box and then hit the "Decrypt"
button

Have Fun!
