Publisher review:JaVi is a Java implementation of Vigenere's algorithm for cryptography. JaVi is a Java implementation of Vigenere's algorithm for cryptography. At this time it works within a Java applet (JaVi2Applet.java). It's built using the Java AWT and it should work on almost any browser.
The first gray panel on top contains information about the version, the copyright and the license. The left panel gives an evaluation of the key strength, printing the percent value. Under the percent a small panel is green if the strength is more than 90%, yellow if it's more than 60%, red otherwise or if the key is shorter than the phrase.
The central panel is divided into 3 sub-panels (panelPhrase, panelKey, panelEncrypted), which contain respectively the plain phrase, the key and the encrypted phrase.
The panelKey contains also two buttons (buttonCrypt e buttonDecrypt) used respectively to encrypt the plain phrase and to decrypt the encrypted phrase. Note that the text area containing the key is editable; so you can insert a personal key, and this is the recommended way. Now if you want to hide the key frow a curious eye, use the nearby checkbox "Visible key".
You can deselect temporarily the other checkbox "Evaluate key" while you insert the key, if the processor is too slow. The button "Reset key" restores the default key (composed by the first ciphers of pi and of the e number). Last, the coloured buttons on the right let you switch from the Italian from the English version.
