Answers to Questions

How to encrypt using Brainfuck code?

Brain Fuck is not a proper encryption system, but rather a programming language that has been obfuscated. Encoding consists in writing machine code that returns text as output.

Machine operations are:

> : increment the pointer (+1),

< : decrement the pointer (-1),

+ : increment the byte in the memory cell where the pointer is located,

- : decrement the byte in the memory cell where the pointer is located,

. : send the value of the pointed byte as output (treated as an ASCII value),

, : insert an input byte (user input) in the memory cell where the pointer is located (ASCII value),

[ : if the pointed byte is 0 then jump to instruction after the corresponding ],

] : if the pointed byte is not 0 then jump to the instruction after the corresponding [

How to encrypt using Brainfuck Shortcut code?

In order to shorter the code, an alternative syntax exists (shortcut BF) that uses i for increment, d for decrement, r for right, l for left each associated to a number to indicate the repetition of the operation.

Example: i4 (+ 4 times) => ++++ , d3 (- 3 times) => ---, r5 => >>>>>, l4 => <<<<

How to decrypt Brainfuck code?

Once again it is not an decryption but rather an interpretation of the code (or brainfuck translator that turn brainfuck to text). Each byte send as output is then a plain text character.

How to decrypt Brainfuck Shortcut code?

Replace iX, dX, rX and lX by respectively +, -, >, < X times to get back the original BF code.

How to recognize Brainfuck coded text?

The message is composed of the 8 characters ><+-.,[] (opening chevron, closing chevron, plus, minus, point, comma, open bracket, closing bracket)

The character [ should appear as many times as the character ]

The characters + and - are the most common and usually appear to +++ group or ---. It makes little sense (but possible) to have + and - consecutively.

The characters . and , are less frequent.

What are the variants of the Brainfuck code?

Many variant of brainfuck have gave esoteric languages such as Alphuck, Binaryfuck, Ook, Pikalang, Reversefuck or Spoon.

When Brainfuck have been invented ?

Created by Urban Müller in 1993
