Encryption/Decryption demonstration app using the S-DES algorithm
...The GUI pops up that allows entering a 10-bit encryption/decryption key in binary (0, 1 digits) and the plaintext/ciphertext in the same form (8-bit). Executing the algorithm, decription of the encoding/decoding functionality is provided in the three main text boxes.
bookHexor use the key.txt for encoding where is saved an arbitrary text, which is used as key. bookHexor read the key.txt and notice for each character, where it can be found as an index. If you encode text each of your charakters is displayed as index.
