Unscramble the Source Code

Question

Note: This challenge is now closed to new cop submissions. This is to ensure that no one can post submissions that only remain uncracked because there aren't enough robbers interested in the challenge anymore.

In this game of cops-and-robbers, each cop will write a simple program to give a single output. They will then make public four things about their program:

1. The language
2. The program length
3. The desired output
4. A scrambled-up version of the source code

Then, the robbers must unscramble the source code so that their program functions like the original.

---

Cop Rules

You are to write a simple program, which the robbers will try to recreate.

Your original program must have a simple functionality: upon execution, it outputs a single string/number and halts. It should give the same output regardless of when/where it is run, and should not depend on extra libraries or the internet.

Your program and output must use printable ASCII (newlines and spaces allowed). The output should be no more than 100 characters long, and the program should take less than about 5 seconds to run on a reasonable machine. You are also not allowed to use hashing (or other cryptographic functions) in your program

Then, you provide a scrambled-up version of the source code and the required output. You can scramble up your source code however you may like, as long as characters are conserved.

Your score is the shortest program you have submitted which hasn't been cracked. After a period of one week, an uncracked submission will become immune. In order to claim this immunity, you should edit your answer to show the correct answer. (Clarification: Until you reveal the answer, you are not immune and can still be cracked.) The lowest score wins.

Robber Rules

Robbers will post their cracking attempts as answers in a separate thread, located here.

You have one attempt at cracking each submission. Your cracking attempt will be an unscrambled version of the source code. If your guess matches the description (same characters, output, and of course language), and you are the first correct guess, then you win a point. It is important to note that your program does not have to exactly match the original, simply use the same characters and have the same functionality. This means there could be more than one correct answer.

The robber with the most points (successful cracks) wins.

Simple Example Robber Answers

Your program was print "Hello World";. (Although print"Hello World" ; could have also worked.)

Your program was print(3**3x3)x3

Answer 1

Python 3, size 74 (Cracked)

Python just wasn't the same after being re-educated by Big Brother.

Input:

print(war is peace)
print(freedom is slavery)

There are two newlines at the end of lines 1 and 2.

Output:

True

Note that each True is in its own line.

We already know the Answer to the Question, but what's the Question?

Code

Note that there are no trailing spaces or newlines. The only whitespace character is the single space after print.

Output

I've attempted to balance code length and difficulty, but it wouldn't surprise me if I missed it a bit either way. Hopefully it's enough to discourage brute force, at least.

Pyth - 71 Cracked

Output

---

*Originally, George Lucas had Han interrupt C3-PO.**

**He called this his greatest idea since Jar-Jar.

---

Interesting note: despite all the changes that Pyth has gone through, there is still a valid answer here!

---

Original

ts,*s,y30 l" : : i i Han Solo "eP-C"h"TsrhT

Explanation

The remaining characters go on the next line. Pyth only interprets the first line of a file.

ts, make a 2-tuple and get their sum -1.
* multiply:
s,y30 l"..." sum the 2-tuple containing 2*30 and the length of the string (18).
eP-C"h"T get the largest prime factor of h's ascii value minus 10 (47).
srhT get the sum of numbers from 0-10.

All in all, this basically just computes: (30*2+18)*(47)+55-1. After reading @isaacg's answer I noticed there is an extremely simple solution: *h30tC"y" which is 31*120.

Updated

*h30tC"y" "-P:Sir, e possibilit,...
Han Solo: Never Tell Me The Odds!"
Still works even after all this time...

Sorry for poor explanation formatting, I don't know how to use spoiler blocks :S (@Sp3000 made it a bit nicer for you, though)

Now you can run Pyth online! Try it here. Thanks @isaacg :)

You can play around with it in the online interpreter.

This should be more crackable than it looks.

Hint

Start with the second line of the output. A few digits don't appear in it all, and others suspiciously often. Why could that be? If you can decipher that, the rest should almost fall in place.

Solution

"that rrrrraging london Hail!v"{elccimf(;W))},(*,pa

The weather must have been pretty bad when I came up with that anagram...

The hint was supposed to point towards the fact that the second line is made up of squashed-together prime factorisations. I was hoping that from there it would be possible to determine how many and which characters go into the string, leaving only a few characters at the end.

Answer 7

Befunge-98, size 15 [SAFE]

Code

"quick"
*+.@\_j

Output

3314

Original

"u_ji@q.+k*c
"

A curious but somewhat well-known feature of Befunge is that you can terminate a string with the same quote that begins it, which in essence pushes that entire line (except the quote) on the stack. As an extra trick, I re-use the same string again, by making use of u to reverse the instruction pointer. Then it's just some arithmetic: the core idea is to sum up all those values (which is done using k to repeat the + operation).

Answer 20

Ruby, 29 [safe]

Trying to see how short I can get in Ruby without getting cracked.

Code

paper view
otool
$()**,.8<<=>

Output

[0][0, 3][0, 3, 6][0, 3, 6, 9][0, 3, 6, 9, 12][0, 3, 6, 9, 12, 16][0, 3, 6, 9, 12, 16, 20]

Original

eval <<p*8 o=*o,$>.write(o) p

Explanation

The first line creates a heredoc that starts on the next line and is delimited by the trailing p, then concatenates the resulting string to itself 8 times. Since it ends in a newline, this effectively creates a loop. The looped code assigns an array to the variable o, consisting of the elements in o.to_a (via the * shorthand), followed by the output of $<.write(o), which converts o to a string, prints it to STDOUT, and returns the number of bytes printed. A variable being assigned to for the first time is nil for the purpose of evaluating the right hand side, so on the first run *o is empty and write outputs nothing and returns 0. Each subsequent round outputs the array of bytes output on previous rounds. Using a p-delimited heredoc creates decoy methods for output, p and $><<, in the scrambled characters, that won't work because you need the bytecount.

Hint

The scrambled code (after the first few characters) describes the output. For each number in the set of natural numbers between 2e0 and 1e2 (2 to 100), output a 1 if it's prime and a 0 otherwise, for 25 primes in total.

Original Code

Explanation

I learned this trick from leonid's answer on an Anarchy Golf problem. The code doesn't actually do a valid prime check, it uses the Fermat Primality Test in base 2, which is probabilistic but is correct up to 341 or so.

Another one, for fun. Might be similar to Shawn's 69 (at least I got the idea while working on it and not succeeding). Outputs using alert, which is already unscrambled for your convenience.

Code

alert(0123)
//((((()))))++...3566777===[[[\]]]

Output

Hint

Here's a hint: think of substitution ciphers.

Solution

for(f
in(g=/56732106737/.source+(h=[])))h+=g.link().match(/\w/g)[g[f]]
alert(h)

The digits in the regex pattern correspond to indices in the string g.link() aka <a href="undefined">56732106737</a>. "underhanded" uses only characters reachable by indexing with single-digit numbers into this string (most from "undefined").

The code will print predefined constant GZ of Phar class which is just compression constant (0x00001000 = 4096). Then the code is encoded with MIME base64 text format and eval'ed (executed). Note that base64 is data encoding format (not hashing or cryptographic function).

Solution

The number, searchable on OEIS, is the sum of the first 23 factorials. To implement a factorial function without any ifs for the base case we use Python's short circuit evaluation and the quirk that 0**0 evaluates to 1.

Intended solution

Awkwardly, my red herrings backfired on me, and I only realised a few minutes after posting.
The intended solution was:

_={};_[6.,...]=_ print(str(_)[-4])

If we print out _, we get:

{(6.0, Ellipsis): {...}}

If you add a list or a dictionary to itself in Python, the string representation replaces that part of it with ...! Yes, that means you can do things like:

a=[] a.append(a) print(a[0][0][0][0][0][0][0][0])

Source:

e=r=p *(0..9).group_by(&:untrust)

Explanation:

e=r= is red herring filler (chosen to create the anagram "puts group_by return"). (0..9).group_by takes a block, passes each number from 0 to 9 into it, and creates a hash mapping distinct outputs of the block to the input. But instead of a literal block, I'm using the & syntax, which calls to_proc on the :untrust symbol to create a proc that "taints" each thing passed into it (which does nothing in this context), and returns the input. So each item in the range gets its own bucket. p * then converts the hash to an array of arguments of the form [key, value_array], and prints each on its own line.

s**$~^wkirgo*ee+print

Explanation

The code performs a substitution which is evaluated, and then the result of that is evaluated (ee). The variable $~ starts its life as STDOUT, so that $~^wkirgo evaluates to $?-=2;.

The variable $? is also special, in that it is stored internally as an unsigned short. Decrementing it by two wraps around to 65534.

The intended solution was ++++[>++++<-]>[>+>>>+>>>>+<<<<<<<<-]>>+++++++>+++++>+>+++++[>++++++++<-]+++>>++>[[<[>>+>+<<<-]>>[<<+>>-]<-]<]>>>>[+.>]. The ASCII values are [113, 36, 86, 52, 121, 81, 33], from which we can subtract 1 to get [112, 35, 85, 51, 120, 80, 32]. This can be achieved by building the numbers [16, 7, 5, 17, 3, 40, 2, 16] then multiplying pairwise.

Source:

Original: 1ss[lsd1+ss+dn11ls<n]sn0lnx
Cracked: [ls+dn11ls1+dss<n]sn1ss0lnx

Explanation

This is made up of a macro [ls d 1+ ss + d n 11 ls < n] that is stored in register n. It loads the value from s, duplicates, it, adds 1 to it, stores that value back in s duplicates the value on the stack, prints that off (n is the print without return), and then compares register s with the value 11. If the value that was in s is less than 11, it invokes the macro stored in register n. A value of 1 is used to initialize register s and 0 on the main stack. The macro n is then loaded and executed.

* Tested on QB64 Windows 7 desktop version. The pseudo-random RND should give the same result every time the program is run, unless seeded by RANDOMIZE. It's likely that the particular result will be different on different systems. But in any case (spoiler alert!)--the unscrambled program does not depend on RND. ;^)

RPL (HP48), 10 characters (safe)

I thought RPL was out of the question, as discussed in my first and my second (deleted) submission. However, instead of creating a program object (with code enclosed in « », and possibly store it), I can just type the RPL code without « » and press Enter to execute the code immediately (kind of command line).

For example, instead of creating the program « 1 2 3 + », I can just enter 1 2 3 + for immediate execution, and the output (addition to the stack) will be:

1
5

Now to the actual (reworked) puzzle that actually follows the rules. Because previous one did not follow the rules, the time for it starts now. (Unfortunately I can't post the other reworked puzzle now because I had already supplied the answer.)

Code (to be entered for immediate execution):

"DO PURGE"

No output (no change on the stack), also no error.

Edit: I'm sure I've given enough time since helping with emulator information and documentation. So I'm now claiming immunity by posting the solution:

"GUE" DROP

Words DO and PURGE are the actual commands and I chose them because they deceive but provide the characters needed. PURGE will cause an error unless there is a name of an existing variable on the stack. Even if that's satisfied and the name is then taken off the stack, how will you get rid of ""? And how will you put a variable name on the stack without ''? It works if the variable doesn't exist, otherwise it gets evaluated. Of course, the behaviour would then depend on other factors, which should not be the case with any code in this contest. DO is for loops and would be incomplete, therefore cause an error (either run-time or syntax).

Original Code

(str(065/.814)*2)[9:-3]
This takes the octal value 065 and divides it by .814 to create a longer decimal value. I then converted that to a string and repeated it twice by using *2. The final part takes a substring of that result, making it harder to know what went on.

original version:

main=mapM print(&);(&)=1:(&)%(&);(16:(:){})%t=t;(e:d)%(l:o)=(e+l):d%o;e<t=e-t

this uses a few tricks:
a variable named (&) that isn't a function

a record pattern not on a record (:){}

a useless definition of < to get people confused what to do with the extra = sign

the runtime prints <<loop>> because we entered into a trackable infinite loop (at the fifth element and on of (&)).

Update: explanation:

As guessed in the comments, this is indeed rot13 encoded. The rules state "You are also not allowed to use hashing (or other cryptographic functions) in your program", but the character encoding defines how the editor interprets the bits that comprise the program, not the program itself.

Answer 208

Python, 90 bytes (SAFE)

Kinda long, but I enjoyed putting this together.

Code:

??(((())))+++++++,1111111111111111111111:;;<<<<======>>>>>[[]]ehiilnnnnnnnnnnpppprrrsstttw

The ?s represent two newlines.

Output:

6167185029251277541387741632208161040852042602130139041952976

Output is followed by a newline. Works in Python 2 or 3.

Solution:

n=11111+1111+111+1;p=str() while n>1111:n=[(n<<1)+n+1,n>>1][n>>1<<1==n];p+=str(n) print(p)

Calculates several iterations of the 3n+1 function starting at 12334 and continuing until the value dips below 1111, concatenating the results together. For obfuscation, uses only 1's and bitwise operators to calculate the function (which would more straightforwardly be n/2 if n%2==0 else 3*n+1).

Hint (though I'm not sure it helps):

If you replace the 3 by a 4 the output grows to 993 digits. For 5 it's even 91585 digits.

Solution:

u=3 print`reduce(pow,(u*u-(oct>id),)*u)`[::u]

Explanation:

Okay, maybe this was overdone. :-) The (oct>id) was a red herring and is just a fancy way of spelling 1 because in Python functions are ordered alphabetically by name. Using tuple multiplication, the argument of the reduce function then boils to reduce(pow,(8,8,8)) which is ((8)**8)**8 or6277101735386680763835789423207666416102355444464034512896. Because this would be an easily recognizable number, it's then converted to a string and only every third digit is printed.
