A Caesar Cipher uses substitution. Each letter in the text is replaced by a corresponding letter, based on an alphabetical offset (shift). Eg. To encode the word 'bimbogami' with an offset of 3 would result in 'elperjdpl'.
Note: The popular 'rot 13/rot-13' cipher is simply a Caesar with offset 13.
'Encode' lets you to encode your text with an offset of your choosing.
'Decode' endeavours to decode your text. Larger texts may take longer to process all the options.
The Sensei's Caesar Solver respects capitalisation/punctuation.
