Answers to Questions (FAQ)

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 :

ReverseFuckBrainfuckOperation
+-Pointer value - 1
-+Pointer value + 1
><Pointer position - 1
<>Pointer position + 1
][Loop while pointer > 0
[]End loop
.,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 8 characters +-<>[]., the only difference being the change of replacement by their opposite.
