The menu Tools contains the following commands and sub menus:
| Codes | Applications of different codings. |
| Compress | Compresses or decompresses data using the ZIP method. |
| Generate Random Numbers | Generates "random numbers" using pseudo-random number generators. |
| Password Quality Meter | Measures the quality of passwords. |
The sub menu Compress is only visible if a window within the CrypTool main window is active (i.e. at least one document is shown or one file is opened).
