What CipherClerk's Applet Is NOT
CipherClerk's Applet is not a tool to protect information. The ciphers
implemented in this package do not provide secrecy any more! They are more
or less outdated. They can be broken, e. g. the original message can be
reconstructed without knowing the keyword, even without the knowledge which
cipher was used! Thus you should not use them to protect vital or valuable
information. This packages is intended for amusement, not for security!
If you search security, go for PGP - a free, state-of-the art cryptography
package available for virtually all computer systems.
So What Is CipherClerk's Applet?
CipherClerk is an applet implementing a collection of historic ciphers.
Most ciphers are "paper & pencil" types, e. g. to use them you wouldn't
need more than a sheet of paper and something to write.
You'll find various historic cipher systems, both substitution and transposition
types. If you've know about Vigenere, Porta, Beaufort, Bifid, and Playfair:
they are all available!
Finally, there are some machine ciphers of the WWII era, too.
ChiperClerk's Applet is not in public domain. It is copyrighted,
but you may use it freely. I tested this package carefully and found
no problems. I think it should not cause any damage to you system. Furthermore,
the Java environment in your web browser is claimed to provide enough security
to protect you from possible damage. Nevertheless it is provided "as is"

Virtual US Army Cipher Device, Model M-94
I wrote another crypto applet / application for simulation the US
Army wheel cipher M-94 and Maior Bazeries cipher
device. It does provide much of the look & feel of the original device.
Since it is not as huge as CipherClerk, it should load mush faster, too.

Expect a delay of a few minutes to load the applet: It consists of
aprox. seventy class files with a total size of 300 KB. There
is a .zip file containing all classes so that a browser can load one file
instead of many. All maior current browsers should take advantage of this
finally, you may download CipherClerk's
Applet for off-line usage (aprox. 900KB). The files contains a compressed
copy of the whole site. Expand the zip'ed stuff into any folder you like
and then open one of the HTML files with a browser capable of using Java
