Press on the options and enter you word you want to encode/decode!
Sadly symbols aren't supported in most methods. Also this Base64 encoder/decoder will not work with other Base64 Decoders/Encoders because this Base64 Decoder uses a different method! But you can still decode and encode successfully! If you utilise this then go into the project and in the lists section is all the albhabets, please note that the vigenere cipher has a space in its alphabet so it can offset some letters ( like b ) same as the Atbash cipher aswell but that should work better
