*ncrypt2

Text encryption tool for kids' spy game - GUI

A Python / Tkinter text-encrypting program for Mac OSX.

Requests a PIN on start-up (it's 2008).

Uses a 4-digit encryption key to perform a substitution (Caeser) cipher.

Can save and open .txt files with embedded key (you may need to add the .txt suffix when saving). Default path is Users/Shared.

At present there is no Setup function to enable setting user preferences.

Scramble button performs a randomized scrambling of the text if you're interrupted while typing your secret message.

Clear text from the screen (Reset) if you want to power off.

ncrypt2's Issues

We should be able to power off

Just as it is possible to power on, we should be able to power off, which would reset everything to the initial state and require power+keycode entry to use again.

Alternatively the Power functionality could be abandoned altogether and the program would prompt immediately for a keycode entry.

We can easily see the encryption key using a text editor

After saving a file, I can open it with a hex editor:

(this was not encrypted, but it is not relevant to the save functionality or this Issue)

After the <?><->, I can easily view my encryption key (in this case it was 1234.)

Ideally this should be hashed, with the salt (possibly?) being based on the encrypted text.

Prompted twice for file path after choosing to save

After clicking the 'Save' button (without encryption), I get a file dialog to choose where to save the encrypted file.

After saving, I get the 'done' message - but after OK'ing that, I get another file chooser box. The best option seems to be to click Cancel on it.

More intuitive starting file path for save

Currently, upon trying to save, the initial path is /Users/Shared. This is not intuitive for most people, who would expect something like ~/Desktop or ~/Documents.
