Answers to Questions
How to encrypt using ReverseFuck code?
ReverseFuck looks like BrainFuck but has the particularity of inverting the BrainFuck language operators to make it even more incomprehensible: the + becomes a -, an opening bracket [ becomes a closing bracket ], and so on. Here is the table to convert BF to BrainFuck and conversely :
| Brainfuck | ReverseFuck | Operation |
|---|---|---|
| + | - | Pointer value - 1 |
| - | + | Pointer value + 1 |
| > | < | Pointer position - 1 |
| < | > | Pointer position + 1 |
| [ | ] | End loop |
| ] | [ | Loop while pointer > 0 |
| . | , | Store input in pointer position |
| , | . | Output ASCII value of pointer |
Example: The ReverseFuck program ----------]<-<---<-------<---------->>>>+[<<<------------,+++++++++++++,<++++++++++++++,>,<++++,-,>, corresponds to Brainfuck code ++++++++++[>+>+++>+++++++>++++++++++<<<<-]>>>++++++++++++.-------------.>--------------.<.>----.+.<. and as the two programs are identical, they display as output REVERSE.
How to decrypt ReverseFuck code?
To know what a ReverseFuck code does, run it with a ReverseFuck interpreter, that can compile it and take an argument in parameter if necessary. dCode displays in a console each byte returned as output as well as the final memory register.
How to recognize ReverseFuck coded text?
A program in ReverseFuck is visually very similar to a Brainfuck code with the characters +-<>[]., the only difference being the change of replacement by their opposite.
