03 How does the multi decoder work?

The multi-decoder makes it possible to run through several decodes at once. This saves time, e.g. all rotations can be checked. Only those results are displayed where there is a valid input, i.e. numbers are required for the back calculation of the letter values.

In the advanced input, it is possible to enter a key to also operate encryptions such as One-Time Pad, Playfair, Tapir and Vigenère. Only the results for which a key is required to generate a result are displayed.

To give you a good start, we have already prepared the most important functions, which you can change at will. Since there are 122 modes for the number systems, we have refrained from activating all of them.

Adjust settings

Use the gear on the right to customize your selection (see top image). Then you can add a new tool. To do this, select the tool you want and tap on the plus to the right of it.

If there are different variants of the tool, you then have the option to decide which mode should be used. If you want to use Bacon as in the example, then simply add Bacon again and select the 2nd mode and confirm with the check mark after entering.

Use the pencil to change the function, i.e. rename or select another mode.

Use the minus to remove the function.

Use the arrows to reorder the different functions.

If anything goes wrong with the settings, the button “Reset to default” can be used to return to the basic settings.
