How does the GC Wizard encrypt or decrypt with a Book Cipher?

What is a Book Cipher?

With the book cipher, the text to be encoded is replaced character by character or word by word with digits. The digits are to be considered as coordinates, i.e. they stand for the number of the paragraph, line, word or letter, depending on the text length.

Decrypt

After entering the key text, selecting the modes and selecting the output format, the decryption of the entered key takes place automatically.

Here the two modes Position (e.g. 1.1.1 1.2.1 1.2.2) or the search for a specific word can be selected as the key.
