Support for Enigma and NEMA would be nice....

Codegroup Project Admin — Thu, 17 Oct 2013 08:26:53 -0000

It would be nice if this toolkit supported rotor cipher machines. I understand that the data structures are not that complex, but that rotors are more interesting than that.

It is not enough to have a substitution table, you have to have a defult posistion -- and with the Swiss NEMA (Neu Machine) -- you would need to have a rotor stepping record as well.

Better help menus

Generally HcryptoJ needs better explanations of the different ciphers and how they work.

Adding RSA to hcryptoJ

Plugin registry

Anonymous — Sun, 16 May 2010 19:44:15 -0000

It would be nice if when adding a new plugin one did not have to modify core source code. One could use the model that JDBC uses by which database drivers register themselves: HCryptoJ has a class (maybe PluginManager) that provides a static method (maybe register()) that new plugins call as part of their static initialization. This call does whatever PluginProvider.put() currently does.

For every cipher engine implemented in CryptoTool there should be a button on the UI that lets you get information about how that cipher words in general and how the particular implementation works. It should include how you create a key for that cipher, maybe show a screen shot, etc.

Keyword based key generator

Ralph Morelli — Thu, 12 Nov 2009 19:52:09 -0000

The substitution cipher uses a keyword to generate the cipher alphabet. But it uses the single algorithm--the keyword is placed at the beginning of the alphabet and the alphabet is filled in with the remaining characters. It would be useful to have several algorithms for generating the key from the keyword. For example, insert the remaining characters in reverse order or place the keyword at the end of the alphabet rather than at the beginning or place the keyword in the middle of the alphabet.

Cryptotool UI feature request

Ralph Morelli — Thu, 05 Nov 2009 19:49:20 -0000

There should be some obvious way to tell which pane of the Cipher frame is active. The user can't tell whether an Analyzer would be applied to the top or the bottom pane. Also, it's not obvious from the UI that the top pane is always the one that is encrypted/decrypted.

User help for Cryptotool

Ralph Morelli — Thu, 05 Nov 2009 19:47:21 -0000

Not enough help on how to use the various ciphers is provided in CryptoTool. There should be explanation about how the cipher works and what kinds of keys are acceptable.

Documentation on ciphers

Sarah Thayer — Thu, 05 Nov 2009 19:33:32 -0000

It would be helpful to have very brief descriptions of each cipher in the cipher files - what, basically, will the encryption do to the plaintext and what exactly are the parameters doing for each cipher. This description is present in some but not all of the engine files.
In addition, for the output, better descriptions of what is going on will help with ease of use. For example:
The keyword is: 12
Algorithm = Railfence
Provider = Default
Plaintext: test this please.
length = 15, nrows=12, remainder= 3, padding character = i
Ciphertext: tsees.titihiiisipilieiai
length = 24, nrows=12, remainder= 0, padding character = i, npadchars used= 9
Plaintext: testthisplease.

Empty Parameter

We should throw an exception or print some kind of message if someone tries to run a cipher with no parameter.
