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more or less outdated.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

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.
To proceed, you may
- read about Cryptography,
if you have no or little knowledge about this.
- read how to use CipherClerk's
Applet, if you don't know about it.
- see which ciphers are available
within CipherClerk's Applet.
- read about things to come and known
- you may start the CipherClerk's applet.
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
- 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
